Alright 2v experts. I put this in my build thread but I figured Id put it here too. Ive got a video of it at cold start and after its warmed up for a few minutes. I had a 95 for 7 years so I know nothing about 2v's. My first guess though is timing chains or tensioners. It sounds like a chain and from my understanding the tensioners use oil pressure? When driving I hear no noise except when off the throttle to shift. The car runs fine otherwise and pulls hard.

My car is having a similar issue and I'm pretty sure it's timing chain related... guides and/or tensioners, primarily on the left side. Other than the noise, the car runs and drives fine, it just sounds like a diesel now.

I've been putting off tearing into it because I don't have the desire or the time to mess with it right now. Actually, I kept comp insurance on it and didn't even renew the tags this spring. :deeplist:

The guides do wear on these engines and can get noisy after 15 years. When I had mine apart @ 95,000 miles I was surprised how good everything looked but I did notice some wear on the guides. I just left it alone since I was building a new long block with all new parts.

The valve train can be noisy on modulars also compared to the pushrod cars.
