A failing D-M flywheel makes similar sounds.

In my amateur opinion this was my first thought as well. Also makes a slight thunk when starting in first gear. I bet that's indicative of DMF as well, right?

I tried to test the noise with clutch in vs. out and made a new discovery. The noise does not occur when the engine is cold - no rattle at all, either during idle or during shutdown. Odd.

Not sure if this helps confirm or deny the DMF theory.

In the meantime I'm pricing out an RS clutch and LWF .

The clutch related noise appears or is more prevalent with warmed up tranny oil. So noise might not me there when the car is cold. To me it also sounds similar to LWF noise, just less. Perhaps Steve is correct on failing DM.

That makes sense to me. By my records it appears that this is the original clutch and flywheel. At 130k its lived a long life.

Shutting down in neutral without depressing the clutch before I changed my DMF resulted in a major "block o block o clock" sound. After replacement, the noise didn't manifest itself again, clutch in or out.

Doesn't sound metallic from the video.

I'm going to close my eyes spin 3 times and pin the tail on a timing chain guide.

Love it . I'll get it checked out by a mechanic and have it properly diagnosed.

Whatever it is, this conversation is getting me excited about a LWF. I can use this as an excuse right? If I buy the parts now, it doesn't matter if it's not the DMF, I can still install the new parts.

Plan made!

Gents,

Would you say all the sounds up until about 18 seconds are normal? I have that slight ticking sound from the lower engine that you do for the first 15 seconds, but sounds like this might be normal.

I think I'm being paranoid

Cheers

I just checked again, I have a 95 with LWF, and its got a clutch that is about 2K miles old, and we machined the flywheel at the same time.

It sounds almost identical on idle. I do get a similar sound from as you after 18 seconds in your clip, but it goes away when I depress the clutch, so to me it's just the LWF sound, at least in my case
