Timing chain noise on deceleration?
Hello, My engine has about 3.5k on it since I rebuilt it last summer. it's an 80 sc 3.0. I am noticing a noise which sounds like the timing chain on the right side during deceleration. It seems normal on acceleration and idle. Is this something I should be concerned about? I put new pressure fed tensioners on. I'll try to post a video or sound clip if I can figure out how to do it.....
Thanks! Last edited by opata; 10-24-2011 at 09:25 AM.. |

I wouldn't drive it until you take a proper look. this can be devastating.

I had the timing chain idler arm on my race car break, ended up grinding up the chain casing and a total rebuild. Old part failure. Don't drive it until you can pull the covers off and make sure that all is good

Good advise. I'll take the cover off this week and take a look. Anything specific to look at? I read post on tensioners loosing pressure. I'll see if the chain is tight. Also, look at the ramp....maybe its loose....Thanks!
