Hey guys, check out this video I took of a noise i'm trying to diagnose. I'm thinking it has to do with timing related components (tensioner) or perhaps a loose pulley (My a/c is squealing at 3k rpm)? Car drives fine other wise. The sound is specifically at 1000 rpm.
About 30k......I really, really need to do it though. I just don't have a feeler gauge, nor have I done it before. As simple as it is, I'm just being lazy. How long does it usually take you?
Yes that is what noise mine was making, this weekend I really started to diagnose the problem, and found that the rattle was coming from the upper drivebelt cover. After I opened up the engine, I found that there was some slack in the belt. This allowed the belt to hit the drivebelt cover. I adjusted the belt and made sure the tensioner wasn't bound up, and the sound went away. The noise was present before the timing belt change because the belt was so old and stretched out, there was a lot of slack. Hopefully this helps anyone else with a similar problem. In my case the noise became very loud around 2000 rpms when the engine speed was slowing down. Because when the engine slows, there wasn't any pull on the timing belt to make it taut.
Wouldn't hurt to check. Replaced the tensioner too? I haven't worked on an M20 in 3-4 years so I don't remember all the ins and outs like I do the M42.
I'm hoping to put a gathering back on the radar such that we can all get together and hopefully I can pull some assistance from you all and have my waterpump/belt/tensioner changed. Might as well do a valve adjustment since we're rotating the crank for the TB job.
Lets see if Bowtie, Scratchy, Old City, and Eddie chime in.
i used to have "tech days" with my VW friends. we would gather at my house and work on our cars. usually one big job and several smaller ones. we'd cookout and just have a fun productive day all together.
Sounds like a plan. I'll order parts this weekend. Til then, lets get a place and time? Perhaps the weekend after this one? I don't have a garage (Riverside) but I have all tools needed except for a feeler gauge and jackstands. A cookout sounds ideal.
You can get them for cheap from FCPEURO if you can't get your hands on locally and you're worried about cost. I'm not familiar with the brand but it's there. You could call them and ask about fit if you want.
