Hey all,
So just getting ready to sell the '95 S14, so I pulled it out of storage (has been sitting for about a year) and did a few things.
One of the main things before when I was driving it was that it had a bit of timing chain noise, so that was one of the first things I fixed. I didn't start it BEFORE I did this fix, but I know when I was driving it previously the chain noise was noticable.
Yesterday I went through the timing chain guide removal tutorial, and all seemed to go well. I took BOTH of the guides. Also, I ensured my tensioners were both working properly. The top one seemed to move well, moves back all the way and pushes the chain forward when released, as it was supposed to. The bottom one was in similar condition. The guides were both worn fairly similarly to the tutorial I used, maybe a bit worse. The chain is tight on top between the gears, little rebound.
So I went back and put it all back together, left it overnight, and threw in a new battery today and started it up. It's making a pretty awful noise, I can't tell if it is coming from the timing chain or the valve train however, but it seems more like the timing chain. I checked the oil (it's old from sitting, but full, I was going to change it after a seafoam)
The noise sounds like a constant grinding, and if you listen closely it seems like there is the odd "ping" as well.
The timing chain itself seems in good condition, no bad wear, so I'm not sure what the problem is. There was also a fair amount of carbon build up on the bottom of the valve train, not sure what that is from. Attached are pictures and videos. Anyone else have any thoughts one something I did wrong or what else this could be?
Thanks in advance for the help!
PS- Yes I know the engine bay is dirty, it's on the to do list!
