3000 rpm

[Uwe]

My 2000 S has the same issue, very faint on acceleration and cruising, sometimes not noticeable, but very pronounced while decelerating when the rpm's swipe through the 3000+- range.
Ive got nothing productive to add, other than seems to be a more common problem than I thought. The engine in my car has been replaced during prior ownership, with a 2002 S-engine. Maybe they didnt do the flywheel at that time. Receipts show clutch components, but no flywheel.
Are there visible clues if a dual mass flywheel has gone past it's lifespan?

No, unless is is really beat up. The correct way to test dual mass flywheels is to use the twist recovery method outlined in a factory TSB.

My 03 base Boxster has done it for the last 160k miles and I assume it did so for 20k before I bought it. It’s very minor and something I have long ago tuned it out, unless I am looking for it.

Nice blast from the past with all the wise old contributors.

Hey Husker, how are you doing?

I have never had this issue with my 2001 S (knock on wood) but my base 2001 had this issue until I replaced the Dual Mass Flywheel. I did that when I replaced the IMS bearing. Yes, that was a few years ago.

Hi Jager.

I'm on the correct side of the dirt. Been a yr since I got the engine back for my CSS b/c of bore scoring, bought an 89 928 S4 5--spd almost a yr ago, had a heart attack a wk before Christmas, and I've lost 25 lbs. Typical yr at the Husker Boxster household.

How's the rocket science business?

Shark #2 Has Arrived

My 997 C4S custom built motor is starting to use oil in cylinder #5. Changed out the fuel injector but appears to be too late, the rings are shot due to carbon/glazing. Going to think about my next steps for that repair.

How's the rocket science business? I was on vacation this week and got called-in to support one of our launches at the Cape. Never a dull moment.

Healthwise I'm doing OK, just getting older and a little slower... LOL.
