Someone wanna listen and see if this sounds like tensioner?

It definitely sounds like a chain rattle. However there is a lot of noise in the video.
Have you used a scope on it? When my tensioner went out, the noise was obviously coming from the chain housing. |
Yes it really sounded from the stethoscope that it sounded like the chain box. I went around the whole engine and the sound was mostly around the box and some around the #4 head. I was pretty sure what it was but the next day the sound was gone. I haven’t heard the sound since. Right now I have the tensioners swapped out for new and did the Jerry woods mod as well. Need to replace a banjo bolt I broke and I’ll be good to go I hope.

Just to follow up on my post #35, I had a rattling noise at low RPM once hot, but it would go away above 3,000 RPM. It would only make noise once warmed up. Sounded like a really bad bearing rattling.
I took the timing chain covers off and found the chains were NOT too loose. I did find that one of my pressure relief valves was not seated correctly. See the pictures on post #14. Exact same issue - the cage came out. I put the check ball back in with the spring and the really loose cage. I put a washer over the loose cage that was the right size to keep the cage from popping out. The washer was retained by drilling a couple of holes in the top of the chain tensioner and adding safety wire. Now my noise is completely gone. This fixed my problem that I have been worried about for 2 years. Now I can drive the car again and it sounds great. |

I did exactly the same thing. It lasted 150 miles.
Maybe you will have better luck. |
I performed the Jerry woods mod and kinda wish I had done that before I bought the new tensioner I performed it on. It seems to be something that would work on a bad tensioner maybe.
