I just removed the plate of the front of the engine to see the chain and oil pump

But normal there has to be a tensioner or demper for the timing chain above the crankshaft gear? that needs to be mounted with 2 bolts?

Please help because i destroyed my camshaft and if the reason of it is that some guy forget to bolt on a tensioner or damper i am really pissed off!

(byt the way, it is a 2005 LS2 6.0 corvette engine)

ls2's have the bolt holes for the tensioner but they do not come with them stock like the ls3 motors. looks normal to me

so this can't be the problem of slack that my camshaft is destroyed? is it recommended that i fit a LS3 tensioner of the plastic v shape dempers?

WOW! No timing chain tensioner! Not Good dude. All LS engines have Chain tesioners here's a pic of a LS2 tensioner

I think that is a upgrade? because i just spoken to Livernois Motorsports and they said that from the factory there are no tensioners fitted from the factory

That's crazy! did not know that... I swore when we took apart a stock LS1 out my buddy's 99 WS6 it had a brownish v tesioner.

Maybe there is a diffrence between the LS2 and the LS1? because i know that the LS3 comes with a tensioner from the factory

No tensioner on LS2's?! I know very little about interior engine mods but I just assumed they all had them. Can we get confirmation from some shops/tuners?

I have the factory manuals and they call it a dampener not a tensioner but there is one there in a 2006 6.0L.

I have the 05 service manual and it also shows there to be a dampener.

Hmmm... strange.. hope more tuners can give answers that often put there hands on LS2 engine's but al the shops i haven spoken told me there is no tensioner or demper on the engine when it leaves the factory..

When I recently did heads and cam on my 06 LS2 (built October 2005) there was a damper inside the front cover, engine had never been apart till then, so my LS2 did in fact come from the factory with a damper.

and i was thinking that nissans where a pain in the *** haha

i will be putting a damper in for sure when i build it back to gether or is it beter to fit a ls3 tensioner?

We have done many H/C LS2 vettes.
05-06 had the black dampers from factory.
07+ had a tensioner.

Dat right, what he said

Somebody screwed up, had the cam/lifter not failed, the chain would have and cost you more money. Who's the dink that used silicone to seal the water pump gaskets ?

Even stock motors have cam/lifter failures but not usually until about 50K miles or more.

This is an early 07 with the tensioner. Early LS1s didn't use anything and then they installed the damper. Early blocks can be retrofitted for either.

I prefer the tensioner. If using a double roller though, it won't be wide enough.
