Just at start-up, or all the time?

2001 with 120k miles so not sure if single or dual row. Engine serial indicates single but going by serial isn't 100% accurate. Original IMS but had RMS updated to newer version and had IMS flange replaced. So far so good...

Original motor, not a replacement.
Babylonboots;
It is very interesting that you have a dual row IMSB on a 2001. Should we infer then that all 2000s like mine have dual-rows and that the switch to single-rows took place sometimes in 2001 vs 2000?
To say the least, I'm perplexed!

2001 was the transition year, not 2000 for single row IMS.

I stand 'cautioned' your Honour, Evangene!
Alpine: Realized after I sent my post that you were in the same 01 boat as Babylon. You might be right ... or Porsche was simply getting rid of their dual-row stocks in both yrs, 00 & 01. We will likely never know for sure.

2003 4S, purchased the car with 90k miles, had the IMS bearing replaced with the LN Engineering kit for peace of mind. The original bearing was in good shape and probably would not have failed. It is now my most prized paperweight.

03 coupe 109,500 miles.....got my car back today! the bearing had VERY VERY little play (probably the same as when it was new) NO damage to the bearing's seals...no nothing at all on the bearing!!! the RMS was leaking just slightly...new clutch and DAMN is there a difference!! SO much easier to acuate! NOT grainy anymore! i also have a prized paperweight!

Ticking slightly in the beginning. When warmed to 180, its constant. Irritating the least. Ill get it fixed... Now how many people have lifter noise ? Hmm... I do the ""procedure's" just to make sure. Or "The solution" for Dual rows if they offered it..
