May 7, 2014 · Bad mouth the IMS in the bargaining, have the PPI note that the bearing is a risk item, buy the 2003 at a good enough price and spend ~$2k on the bearing installation. Do the AOS while in there. You are looking at an 11 year old car and there are parts (plastic and rubber primarily) that go bad from age as well as miles.

Mar 30, 2014 · Yes, I replaced the IMS for the updated version when I had my clutch replaced at 110,000 miles, but it turned out to be in flawless shape anyway. To answer your question directly: the IMS issues existed until Porsche did away with it upon the introduction of the completely new Direct Injection engine fir the 2009 model year.

Feb 3, 2011 · Unfortunatley your question regarding IMS longevity is a question that has as many answers as there are Boxster owners. There have been reports of IMS failure in a few thousand miles to a hundred plus thousand miles and up to the 2006 year when the whole IMS part of the motor was changed it seems to be a crap shoot.

Jun 1, 2012 · The IMS though is a different story. (OK - IMS seal leaks can occur, but like the RMS these are harmless and easy to fix.) IMS *bearing* failures are a real problem. The bearing that supports the intermediate shaft was poorly designed and prone to failure. It gives little to no warning before it fails and when it does fail it destroys your motor.

Aug 15, 2015 · All M96/97 engines with IMS bearings are at some level of risk for IMS bearing failure, the only thing that changes is the percentage that fail. A second problem, which the seller completely forgets to mention, is that many of the 2005 cars came equipped with the non serviceable (read cannot be changed without total engine disassembly) IMS ...

Mar 29, 2022 · The only replacement IMS bearing that does not need to be replaced after being fitted is the IMS Solution. Many shops recommend replacing the water pump, air oil separator (AOS), rear main seal (RMS), flywheel & clutch, and carry out any and all deferred maintenance while replacing the IMS bearing, so be sure to set aside money to carry out ...

Jul 30, 2016 · The Boxster has 67,000 miles on it. After reading about the issues with Porsche IMS bearing failures, I like to replace the IMS bearing as a proactive measure. I took apart the clutch and looking at the IMS cover is the shallow one. I am assuming the IMS bearing is a double row. The market is flooded with a mix of IMS replacement parts.

This makes 996's a steal for the performance you get. The initial IMS bearings were greased and sealed for life. The problem seems to have been that when the cars are only driven a very little bit (like 1000 miles/yr) the grease dries out. Porsche changed the bearing, eliminating the inner seal, so engine oil gets into the bearing lubrucating it.

Sep 28, 2022 · IMS might be an issue on 2005 cars (small single row bearing) and is a nothingburger on 2006+ (large single row bearing). It’s not an issue on .2 (9A1 engine) since it doesn’t have an IMS. It’s permanently fixable on .1 engines by running an oil line into the IMS. Bore scoring is far more frequent of a problem on .1 cars.

Feb 9, 2012 · I was told by a Porsche master tech at a dealership that there was an IMS bearing change made in mid-05 on the 987s. This may be to the "bigger" bearing mentioned above. It factored into my decision to buy a used, high-mile mid-year 06.
