I can't argue with that. Looks a nice bit of kit mind. 8)


Hi Kingston, that's too loud for me that. :eek:
Plus I have the full Cargraphic system on mine including cats and manifolds, so quite content on the exhaust side of things. That's the joy with induction kits. Small throttle inputs and noise is like standard. Rev it though and it screams.
I'm not doing anything yet though. :thumb:

Hi Dr No, thanks for the comments. I'm the same with passwords. :grin:

Yes get a thread up about your car. They are good to bounce ideas off people on here and things. Best thing is though it's just a good log to keep on your car.
When you look back later you realise how much you've done and see all the little jobs and changes you've carried out to make it your own and improve it.
Plus everyone likes a picture whether it's a project, road trip or track day pic.
Cheers. :thumb:

That is indeed awesome lurking !! :grin: :grin: :grin:

Hope you're well Mark, sorry I've not responded to your last email, been flat out fettling the GT3 whenever time allows, I've clocked up at least 150 hours fettling the old sh*tter :grin: My labours have however been rewarded, It's actually a really nice car to drive now, finally ...
 
Righto, update time.

What have I been up to? Not that much really but the pace is picking up now with my trip looming.
Basically my 'Don't pull this one to bits" mantra has failed me. :grin:

I'll try and put things into some sort of order as some jobs have blurred into others, but anyway.

As usual it's just boring maintenance and tweaks so nothing exciting and again, these posts covering the run of the mill stuff are mainly a diary for my own benefit. They aren't going to have anyone on the edge of their seat. :D

Anyway here's away.... I didn't finish up covering my interior clean from last time, but to be honest I didn't get as far as I'd have liked. I wanted to use the car for something so ran out of time. So instead of treating all the interior leather and seats with Gliptone etc, we ended up chucking them back in for now.
We also left the cage out ready for my trip.
I did get the carpets all hoovered and wet vac'd though.
Definitely worth doing to any used car interior. They never seem that dirty until you see the water. :eek:




Before




We also took the opportunity to tape down the old electrical seat connectors, to eliminate any rattles from them.

After




One quick Saturday job I still had to do was clean out the other 3 arches. I only actually 'needed" to do the 2nd front one really to monitor the 'misting of oil on front dampers", which was an advisory on the previous mot.
So far there's nothing there but I'll assess it once the car has covered some decent miles.

As was the way with June it would be sunny all week when I was stuck at work but then rainy come the weekend. So one wet Saturday I donned my waterproofs and got the car up on ramps.




Craig bought the new ramps above (not a great pic to be fair). They're only about 75mm high maybe, but are great to get the car up initially and they aid getting jacks under massively.

Wheels off and greeted with the usual wheel arch grime. I must stress this wasn't going to be a proper arch detail etc as I wasn't even removing the liners at this point. It was simply to get the thick off and also to carry out another small job while the wheels were off.

NSR before -




NSR after -
(The eagle eyed among you will spot a missing bung on the inner arch. I'd blasted it off with the hose. I found it under the car and popped it back in. :wink: )

My car has the Manthey Racing KWV3s from JZM. I'm a big KW fan having had them on my C2 as well. As I always say, they ride really nicely and not crashy.




So once things were a bit cleaner I tackled the next job. Squealing bloody brakes!
My car has Alcon discs with Pagid RS29 pads. They squeal like mad around the doors but I don't want to bin them as they're very good.
I was going to swap the RS29s out for some DS2500's but like I say, the Pagids are great in every other aspect apart from the noise.

I pretty much knew before I done this job that it wouldn't do much as basically the pads are squealing due to being a few years old and not having been tracked much in recent years. If you don't work them properly and get them up to the temperatures they're designed for then they essentially go off and squeal a lot.
We also found the anti-squeal pucks are missing from the pistons which won't be helping. They just come off anyway if you track them though, hence a lot of the track lads leave them off.
So we stripped the pads out, cleaned them up and applied some of this stuff to the rear pads faces and any contact points, including the retaining pins. Worth trying for a couple of quid.




Did it work? Kind off. Definitely better but they still squeal. Like I say it's most likely down to the actual pad material now though, so I may stick some road biased pads in for next year. I'll keep the RS29s to throw in for trackdays though, as I hope to do one or two a year... possibly.
I have one more thing to do to the RS29s for good measure before my trip though, just so I know I've done all I can with the existing set up.

More to follow. Cheers. :thumb:
 
I have the exact same brake set up on my Turbo, and they also squeal like feck!

I've kind of accepted it now in a 'because race car' kind of way....!

MF.
 
RS29's are known for being noisy when used as road pads, they need quite rough treatment to minimise squeakiness. The gentle type of braking you do in road driving tends to 'polish" these pads which leads to the noise. Try doing an Italian tune up or better still a trackday, the frequent hard stops should help decontaminate the pad surfaces and reduce noise. Until of course you go back to using them on road again and the fun starts all over... :grin:
 
Hi Mark, good to hear from a fellow sufferer. :grin:
Most of the time I'm like you and think exactly that 'because race car", but when I'm not in the mood and particularly in towns when you have folk turning around to see what's making all the noise, it's gets annoying pretty quickly.
Tremendous brakes though. 8)

Hi Roro, good summary and that's exactly what I'd been led to believe.
Like I say I'll use them until this autumn when the car comes off the road and I'll probably throw them in my spares box incase I want to fit them for a trackday.
I have just added some self adhesive anti squeal material to the backs of them. That's everything I could try, erm, tried now. :D
 
Marky911 said:

Hmmmmmmmmmm, tasty 🍽 We need to try yours and then mine back to back to compare :thumb:

My brakes are the same as yours and they don't squeal much. Although recent more gentle use has made them squeal a bit.
 
Hi mate, funny you should post. I've pre-written my next instalment and I've actually said in there that we'll be due a catch up at some point. From your point it's to compare suspension. From mine it's the tickover. :wink:
We may make that September trip but it's probably more no than yes at the moment due to my big trip.
There's also a trackday on at Croft in September, but I don't have track Insurance this year so I may leave it. I'll keep you posted.
Either way we'll sort something because after September we'll be into winter before you know it. :thumb:
 
Ok, so last week it was service time. The short version is all is well.

I will use this post though to cover a funny thing that had been bothering me since I bought the car. It's a very minor issue but I wanted to look into it a bit more.

Basically when you start the car from cold it fires up and idles lovely, at about 1000 rpm or whatever. After 30 seconds to a minute the fast idle then cuts off (as it's supposed to) and the revs drop to a pretty stable 700 rpm.
However imagine you have the constant tone of the exhaust like any other car. That's fine, but as well as that you get these funny little pop-pops every second or two. No pattern to them and not in time with the engine but just a little unevenness, almost like small misfires.
Now I mentioned this when I viewed it and was told 'It goes through the workshops, blah blah".
Pre collection I asked if they'd found anything and was told 'No misfire present, it's the same as the other GT3s we've known".

So anyway I got it home and was obviously chuffed to bits with it. It pulls like a train and the performance difference between it and my old C2 is greater than I expected.
The little pops were bugging me though as the new car buzz wore off. It has the Cargraphic exhaust which I know exaggerates them and a Parr remap, which I was starting to question. Could it be that?
Everyone I knew said 'Just drive the bloody thing", but I'm a fanny and I wanted to know the motor was sound and safe as it has seen very little use with the last owner.

The only guy I'd trust to look into that would be Wayne Schofield of Chip Wizards. He needs no introduction on here as he's simply the best in the business. I met him when I had my Mk1 GT3 as he used to race in my mates Championship, but I never ended up getting the Mk1 done.
Anyway we all know how hard he is to get hold of as he works long hours and has his head in his work.
As luck would have it though Craig had a slot booked for his C2, so we decided we'd head down in two cars and see if he'd have time to look at mine too.
(funny story about Craig's booking. He basically had a two year wait) :D

Anyway, the week before our booking we decided to eliminate any simple things so we fitted new spark plugs (due in my service soon anyway) and fitted a 'known to be good" set of coilpacks Craig had.




All 6 of the old plugs looked perfect on removal, a nice light brown. We thought we might have found one that was different, signalling a firing problem, but we didn't.
We fitted the new ones and there was no difference after starting it up, so it was off to Wayne's as planned.

We went down one Sunday night and stopped over so we were at Waynes first thing Monday morning.
We felt a bit cheeky rocking up in two cars but we'd had no joy getting hold of him on the phone to ask.
Wayne had no issues with looking at mine though as I explained it was new to me and I had a 3500 mile trip planned.
(Ignore the mess. Wayne had just moved from the unit next door).




Wayne started by going through all of the standard systems first.




Everything was functioning perfectly though, every sensor, solenoid etc.
So next he removed my ECU and took it into the office to learn more about the map. Most remaps have a 'read protect" built in to stop other people accessing them.
However, Wayne showed us that by jumping certain pins on the chip you can gain access.

Wayne also said that Parr won't be doing their own mapping and it would just be a downloaded map. Sure enough it was - Superchips.
Again though it all looked fine.
Only one thing stood out as being less than optimum and again Wayne had already warned us of this. For some reason Superchips program in a load of ignition advance at idle. Mine wasn't the worst he'd seen at about 4.5 degrees but he said it didn't need that. So he cut and pasted that section of map from a known good map (actually Mikes from S&C) and laid that over instead.

He said it may or not sort my little pops.
It didn't.

So that was that basically. Wayne had done all he could and proven that all the electronics on the car were spot on.
He said the next step would be to get a leak down test done as a precaution, to check the actual health of the engine internals and valve gear, incase someone had buzzed it (over-rev'd it) and clipped a valve or something like that.
We didn't think it would be that, as the lumpy idle isn't that heavy and has no pattern to it. Obviously bent valve noise runs in time with the engine.
Also my Rev range history was great and the car runs perfectly everywhere other than at warm idle.

Wayne said if the leak-down test came back good then it obviously couldn't be too much to worry about. In fact the only other thing he could think of was that it may be a fuel injector with a less than perfect spray pattern at idle, when it's not under much pressure. Again, all plugs being the same colour meant not much else untoward could be going on.

With that, we headed home. We had a good day at Chip Wizards. Very informative.
I would like to add that booking is now much easier as Wayne has just rolled out online booking. You have to put your money where your mouth is and pay a bit upfront though, as Wayne gets all sorts of time wasters, from no-shows to cars that are simply not in a fit state to go on the rollers. Understandably he needs to separate the wheat from the chaff.
For us genuine customers though it means we can book a slot much easier. Just make sure you've eliminated as much as you can yourself if something isn't right and make sure your car is fit for the rollers. :thumb:

Back to mine then and I already had the car booked in with my Indy for a major service and full going over, so we added a leak down test to the list.
Trouble was I had a 6 week wait after Wayne's until my service date and in that time, despite all the evidence suggesting the engine would be fine, I managed to convince myself the engine was kaputt. :grin:
Not a fun few weeks wait. Thoughts of having bought a very expensive paperweight entered my head etc. Bloody cars! Why do we bother eh?? :D

So as I've said the car went for it's service (which I'll cover next time) and leak-down test a couple of weeks ago, with Jamie at Nelson Porsche Stockton. My mate and Indy for over 15 years now. Blimey.

He was the bearer of good news anyway. The engine is in rude health with barely 5% losses in each cylinder and almost identical across the board.




Phew! Quite a relief. Logically I knew it would be but sometimes the more you read about something online, the more you think you're doomed. That goes for health as well as cars eh. :wink:

Craig sent me this though and reckons this is the real reading. Jamie just didn't want to tell me. :grin:




So what now? Probably nothing.
I may stick a set of injectors in at some point but again everything you can check is fine and all the old plugs were perfect, so am I chasing a problem that isn't there? I welcome any input from 996 Mk2 owners. I need to meet up with me ole mate YK off of here and compare cars.

I also stumbled across this thread specifically about 996 Mk2s where a few people said the idle should be smooth, but equally a good few said theirs was lumpy/had a missing feel to it.
This was way back in 2008 when the cars were only 3-5 years old, so I don't believe that all the lumpy cars were faulty without their owners knowing it.

Just to finish this part, Craig's day at Wayne's was even less fruitful than mine, but I'll let him cover that in his thread.
There's always something. :wink:

Next time I'll cover the service and the whole heap of work I'm half way through at the moment. With my trip drawing ever closer I did not want the car pulled to bits so much at this point. I'm gonna have no time to get any miles on it beforehand now. :eek:

Anyway, thanks for reading. Back to more picture based posts soon I hope. :thumb:
 
Forgot how good this thread was :thumb:
 
Cheers Marty. I'm just rattling through the mundane stuff I've been upto since buying, but it's all info, some of which may help someone if they ever stumble upon it. :wink:


I'll quickly cover the service work then. I usually gather all my parts beforehand but I didn't want to waste money on expensive oil until we had the leak-down results, just incase.
This meant that once Jamie gave me the good news it was a mad dash to order what we needed and have it delivered straight to his place, hence no pics.

The list of works was this -

Leak down test.
Major service inc. all filters, fuel, oil and pollen. BMC panel replacement air filter fitted, so air filter not required.
Engine oil - 10w60 Millers Motorsport.
Gearbox oil change - Motul Gear 300.
Both of the above recommended by GT3 specialists and Opie oils.
Investigate suspension creak and free off all bolts/adjusters for future alignment.
Intermittent wipers in-op.
Check auxiliary belt pulley bearings for play.

The above is self explanatory really.
All the suspension bolts cracked off no problem so the car can be booked in for an alignment soon and there'll hopefully be no issues on the day.

The creaking was actually stones that had been flicked onto a ledge of the subframe right next to the anti roll bar. Every time the bar twists it tries to crush the stones and sounds awful. Crap design actually.
Easy fix though. Flick the stones out.
Buckle up for some high octane footage. :grin:

https://youtu.be/xrSJPS7pV8g


Auxiliary belt pulley bearings were all fine.

Intermittent wiper issue is usually due to the switch/dial or the relay. It was the latter in my case. Another easy fix.




In addition to the above work Jamie also found the clutch pedal switch to be faulty so fitted a new one of those.
More importantly he found that my alternator wasn't charging properly.
This was at tick-over with everything switched on -




This was at 2000rpm with nothing switched on -




Well surprisingly the warranty I got with the car, which I presumed wouldn't be worth the paper it's written on, actually coughed up for a new Bosch alternator and fitting worth £350. Result.
If they hadn't I'd just have had the original one refurbed but now I've a nice new shiny one on there.




I still wouldn't want to rely on the warranty for any in-depth claim but I may be wrong.
In fact Jamie was going to try for the wiper relay too but I said just concentrate on the alternator.

There was no brake fluid change required as that was last done in October of last year by Autostore. Castrol SRF used throughout the cars life.




Two final things found.
Firstly a corroded power steering pipe crimp -




Removed and a jubilee clip fitted -




Then lastly this -




Oh *****. Leaky condenser.
My air-con was nice and cold but a bit whiffy so I'd already purchased a Groupon voucher for an ATS air-con re-gas.
A bit more work would now be required before I could go for that.
Me and Craig are sorting that but we've had a 'mare with some of it and the car has been off the road for almost 3 weeks now as we only work on it on a Saturday and each of the last two Saturdays something has come up with parts etc.

I'll cover the whole job next time. Suffice to say, things have snowballed. :frustrated:

Oh just before I finish, there were 2 advisories from the service. The first being the air-con condenser leaking and the second was the high tone horn not working - Now replaced with a decent used one.

On the plus said Jamie said the car is spot on with no horror stories and very genuine and original. Particularly underneath there no weeps, leaks or bodges to anything. So I should hope so really, as it has only covered 44k miles. :wink:

As ever, thanks for reading. :thumb:
 
Pleased it looks like being a good one for you

Thread always makes fascinating reading 👍
 
How comes you switched to 10W-60 oil?

I take it you know that the rads on ebay are the same as OEM and half the price etc.
 
Hi 917, thanks for the comments. Yes I can get stuck in now I know it's AOK. :wink:
How's the R going? Serving you well I hope. :thumb:

Hi Kingston. I've gone for 10w60 as that's what all the GT3 specialists put in and it is all my car has run on in recent years apart from the water thin Mobil rubbish that Autostore had put in.

The rads on EBay are decent copies whilst not identical. OE quality are Behr/Hella which are available for £160 a pair. I went with ones from my local rad place, which cost about £90.
I bought my condensers off eBay and just received my refund today as they were shocking quality. I ended up getting replacements from the same Rad place up here too. A little bit more expensive but I should have just done that in the first place.
