Great progress J. Cool

I'm guessing without new pistons it would have been nearer £8500k.
Not bad at all.

Cmon then get cracking, have you not got it run in yet. Very Happy

Ha ha! OK Marky .... How's this?:







Flywheel, Clutch, Gearbox and air distributor and exhaust boxes to go, then back in it goes......

You may have noticed that there is no air con compressor? The story to this is, that the aircon hasn't worked since I got the car. Originally I thought it was just a leaking condenser which I duly changed and re gassed. That lasted a week. Then noticed green fluid all over the compressor, which I took was a leaking seal from the join near that location. Changed it, re gassed, lasted a week..... then phut! frustrated

Also one of the main pipes it a horrid lash up repair that doesn't appear to leak, but I don't like it. So to be honest I'm fairly pee'd off with the aircon system. I don't particularly want to spend more money on it, but its certainly nice to have.

The options are to leave it off............
Hmmmm, saves a bit of weight, probably don't need it for most of the year, and prefer driving with windows down anyway, just not on the motorway.
Or, put the compressor back on and get round to fixing it when I can work up the motivation.

What do others think?

Pedro, Thanks for the interest. I must admit I thought long and hard about fitting a LWFW.

I had previously said that I would get the whole engine balanced and a LWFW etc etc. but in the end I decided that the car is required to do a bit of everything, not just a Sunday morning thrash about. And one of the reasons I like the 911 (And its been said plenty of times by others before me) is that its great at everything. I like the compromise that Porsche came to and don't want to push it to far from that.

Though it has to be said, its better to go LWFW, balance everything etc and then go back to a dual mass FW, if you don't like it. Rather than just fit one and then keep your fingers crossed the crank isn't going to snap (Rare occurrence I know).

Will update a bit more tomorrow...

Good progress!

Air con compressor is easy to get on at a later date, just need to drain the PAS reservoir to do so. You'll need a shorter ribbed belt if you don't fit it.

I would get it working though.... well worth it for winter de-misting and motorway.

Why did your engine need new cylinders?

I often end up putting the aircon on when i've got the roof down, simply because the car is so much happier idling at 800 rpm than the 620 it idles at with the aircon off. I know that this is likely a really stupid thing to do, but there we go. I also enjoy the cool air.

Good points Wasz and Dammit

That is the only other reservation I have. I still put the aircon on to raise the engine revs at idle. If its not connected, I'm not sure the idle will increase and the low speed fans come on. Anyone any ideas?

Wasz, nothing except an increase in ovality (If that is a word) that would only increase. I did toy with the idea of 6 x support rings, keep the pistons, new standard IMS bearing and bang it back together with new bearings and chains etc.

Cost I think would have been about £5,500 (don't know this is an educated guess). In theory then, that would be pretty much the same result but £4k less. I went for the upgrades on the basis do it once, do it right. But I can equally see that another owner else might see things differently.

Id swap out the pump at this stage even if the system needs work. Its easy to just fit the non aircon belt then swap over once system is working.

Ive been running like that for approx. 2000miles

A 'standard' rebuild will run about £3k + VAT
Ref: http://www.archermotorsportservices.co.uk/index.php/engine-development/watercooled-porsche-engines

Thats the price to pull it all apart, refresh whats there and check for damage (if any)
This wont include anything to rectify the cylinder issues however - thats another £300-400 a piece (3 or 6) plus associated bits (water pump, coils etc).

...my 70k miles 996 tip 3.6 engine is currently being rebuilt and thus far I think we are close to £7k in parts from Porsche; including all the timing bits,all of the variocams (4) I think; all of the oil pumps (3) I think? Plus a new (latest design) ims shaft with carrier and bearing plus a load of other stuff...ltt,aos etc...oh 6 new ringsets...

I am having the crank polished and the heads skimmed and rebuilt plus honing of the bores...

I reckon that the total cost will be close to £13k which when coupled with a £16,500 purchase price leaves me £30k in for a car worth;shall we say £20k!!!

Ouch...

Two of my new cars depreciated more than 10k in 3 years just to put it into context. At least you have a nice shiny engine to show for it!

A/C will still raise the engine revs regardless of wether there is an a/c compressor fitted or not .. the system doesnt have to work to increase the revs basically .

Compressor can be fitted later but its the dehumidifying propertys of the a/c system that are most benificial and not just the cold air .

I think you guys with idle issues without the aircon have some problems.

My idle was a bit erratic, worse with air con off and easy to stall at idle manoeuvring.

Since then I cleaned the throttle body, un seized and cleaned out my idle control valve (mines a cable throttle), replaced the AOS and seals, and smoke tested the inlet system for minor vacuum leaks.

I also replaced the clutch and fly - was heavy and a bit on / off.

The idle is now rock solid air con on (900ish) or off (600ish) and the car is a pleasure to do low speed manoeuvring like parking, no need to rev it up like an idiot anymore to avoid stalling.

See my threads in my sig for details, and here for idle valve: http://www.911uk.com/viewtopic.php?p=1391891

My car doesn't stall/lurch/whatever - it just doesn't seem very happy idling at that speed. I discussed it with Grant from Hartech and he said said that they raise the idle speed when they remap the cars.

Very very tired!








But pretty pleased with myself. Its in but nothing connected up yet.

Mine are similar to your idle speeds Wasz. The only issue with 600 rpm idle the engine *did* have a propensity to make a ticking noise at the lower speed when hot. In fact all three 996's have done it. Put the aircon on and the idle speed increases and the tick disappears.

Think Baz has already posted about the origin of the term"Tick over" Engine speed was increased at idle until the ticking noise caused by uneven forces in the engine smoothed and balanced out as the rpm increased to the "Tick over" speed. (In the days when you could adjust such things with a screwdriver....

Anyway thanks for all your thoughts on the aircon system. I'll run it without the compressor for the moment, and get it sorted later.

I've also cleaned out the Idle control valve and throttle body. AOS is new, AOS lines all cleaned out, as was the intake which had a fair amount of oil residue stuck to the inlets.

Fingers crossed it'll be running tomorrow.

GMG - I feel your pain. Impressed so many of us are getting rebuilds at a huge cost. I'd have thought many more are going to be broken for spares, but then I don't see that many on ebay in that condition.

Good luck and hope you are back on the road soon.

I had trouble with pushing the hard aos vacuum line son in situ.

Turns out the seals inside the connectors had gone hard and I had an air leak when I started up.

Putting new seals on those was not easy.

Congratulations, a lot of hard work nearly over - exciting.

The aircon pump is a bit of a b*gger to replace because of the bolt at the back. Also, the temp gauge sensor between the intake manifolds can be a nightmare to replace with the engine in situ. However, I think the aircon pump is also fairly reliable and probably not the issue.

So close, but run out of time, and now back to work for a while..... Just got to bleed the clutch and fill up with fluids.

Many thanks to Demort for coming ove too. Really great to have an expert eye cast over things.





Looking OK though.
