L99 Timing Chan Tensioner Broken - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

John_C · 03-22-2018, 12:42 PM

So during my heads, cam, etc., install, a timing chain tensioner was found broken at just 33k miles.

What is the fix for a bullet proof setup?

Will this work? http://www.jegs.com/i/Cloyes/220/9-3673TX3Z/10002/-1

What i did as well as many others on here is to swap it with an ls2 dampener. The link you have is for a whole timing chain set but the tensioner pictured is the ls2 dampener. Unless you need the whole kit then you could just buy the dampener by itself and it’ll be much cheaper.

We upgrade all Camaro's to the LS7 solid tensioner to alleviate that issue.

LS2 or LS7 damper is the ticket!

LS7 version:

32k at the time, mine was still ok..

Mine broke at 20k

Bo White · 03-22-2018, 02:46 PM

Mine was broke at 65k.

Silver14 · 03-22-2018, 02:51 PM

Any tell tale signs prior to pulling the timing cover? Can you hear the chain rattle or anything before complete failure?

what is the difference between the 2 other than the color? is there one? tks!

hammdo · 03-22-2018, 05:05 PM

From what I was told, this is the GM ‘performance’ damper/number and is made to withstand more timing chain slap/performance use. Could be different material than the LS2 version (looked like it).

That’s all I was able to find out about it...

Got the LS2/LS7 damper.

Should I atleast upgrade the stock timing chain, too?

C5R chain would be a good upgrade/replacement
