Something positive on 996


Recommended Posts

I was wondering if I have the only 996 911 that has few problems. If you read the forums on the internet it makes one feel like there are no 996s that have over 100k on them. If someone has one please leave a commit. I have 106,000 on my 1999.

no reason to believe that 996 engine will not go beyond 100k. Porsche has always had some engine issues over the years.

the 911sc had a problem with sealed timing chain tensioners, and most owners updated to the carrera hydraulic tensioners for peace of mind. I did, and sold my sc w/325k on it. Well, ok, had to do major engine work at 160k.

I've read that if you retrofit the ims you can expect good reliability from your 996. I hope so, as I just did the retrofit on my car.

Will my C4S go to 325k? Will I? Hope we both do....

If your car is eligible for the LN Eng retrofit I would do it at your next clutch change. Keep in mind that the retrofit is not a cure for the inadequate lubrication that I suspect contributes to IMS bearing failure. The retrofit simply allows the bearing to be replaced without requiring engine R&R and full tear down--major savings there. Unfortunately, 996 with later model m96 or engines replaced in q4-05 or later may not be candidates for the retrofit. This is the 13mm versus 22mm IMS nut topic that you have probably heard about.

glad to have just had the LN retro IMS and clutch work completed. another tip would be to use the right oil (no restarting of any past oil wars intended), and, importantly, I think, keep rpm's down until the thermostat is open and the engine reaches running temp. after that, keep the revs up just as you would on the air cooled engines. No lugging on the engine, please. I agree that oil circulation is likely crucial to IMS issues.
