PostPosted: Thu Aug 01, 2019 3:23 pm    Post subject: Update on The IMS solution Reply with quote

Hi all
I posted a lot longer ago than I realised, in fact back in 2013, about the then newly introduced
The IMS Solution which Revolution Porsche (RP) agreed to trial on my car.

My 996/C4 is now on more than 90k miles and this is an update; Last year Gareth Merrick at RP mentioned that there was the most fine film of oil on the oil filter itself and he was reluctant to strip the spin on filter adapter from the oil filter boss as he needed to know the exact part number of the O ring sealing the adapter (provides oil feed to the new bearing) to the block.
As I was in US, I agreed to call same number I used to speak to Jake Raby in 2013 and the phone was answered by someone called Jud.
Jud said that he thought that the O ring was the Porsche part used with the original oil filter and would get back to me.
Within about 20 minutes I had an email reply from Charles L Navarro, (of LN Engineering) who gave me the Porsche part number for the O ring but also said that if we for any reason needed a new filter adaptor, he would send one.
Gareth replaced the O ring and the oil film disappeared and stayed disappeared..
I mention the above because I was impressed with the good customer service which LN Engineering responded.
I hope that this posting is helpful for anyone interested in this different approach to the IMS problem.

Me too - 1998 engine with 130k on the dual row bearing it started life with. Annual oil changes and drive it like I stole it.

105k here on a 1998 C2. Here's hoping it lasts as well as the ones above!

Re IMS solution mentioned originally, any issues or feedback about how it operates?

I don't follow too closely as both of my non-Mezger ones are early engines, but is thar the single row or the later big bearing?

115k on mine - bearing was changed out at about 87k when Hartech rebuilt for piston slap (on a 3.4)
That's been a few years ago now - oil changed every year and driven in all manners of style Very Happy

987 S 2005 Last of the early engines .

I've not seen one in a long time now .. this is the classic 13mm nut snapped off the bearing and dumped all its oil .

Back when these used to be a problem .. pretty much when i started on Porsche ( 2004 ) the classic sort of mileage always seemed to be around the 40k mark , not always but its a milage i saw a few times .

Strange this one was at this mileage as it would kind of indicate its milage not time based .

My own opinion is once passed this area of mileage then i feel there's very little chance of it failing ... as i said .. i've not seen one in ages now .

i only really know what i've seen over the years and am in no way an expert .

Makes sense. I will be running the later big bearing in my rebuilt engines. Happy with the early dual row bearings. God knows why they changed it!!

Mine 996.2 C2 was swapped recently at 86k. In for oil leak / clutch and showed signs of play so done as a precaution. I asked for the old bearing back expecting some huge hunk of steel but its about half the size of a wheel bearing @ approx 40mm dia. Was shocked by the size and how much they cost to replace and how much catastrophe they can cause!

Sleep slightly better at night albeit replacement in situ comes with its own problems. Current plan is to run for 2 or 3 years (100k) and visit hartech.

I'm pretty sure the LH one is about £500 just to buy it from the company ..

You have to return to them the old one though as they warranty their bearing and wont do so if the old bearing has already started to break up and put metal into the engine .

My guess is you havent got this type .

Knocking on 139k miles on my dual row IMS, '99 3.4

It gets redlined every time I drive it and fresh oil every 6k.

replaced my bearing with EPS at 145k. the original one had shaft play - but nothing too serious apart from ton of oil being dumped on it by leaking RMS
