timing chain Dampener New VS Old
ok. i have done a few cam swaps in my day and i have replaced the dampener ever time i have done them. well i ordered a new LS9 cam for a build so i got the ls9 dampner with it.
well all the OLD style ones are a black looking piece.
and the New LS9 style is a metal brake with to peices of plastic on it.

^^^ you can see new style in this video at 1:44 min adn then it shows more of it later in the movie
Question is
what is the benifet of the new style?
should i start using it on all the cam swaps. or is the black on better?
thanks

I was faced with this decision when I built my LS2. The newer design is a spring loaded tensioner with plastic shoes. The design allows the shoes to keep slack off the chain as it wears/stretches over time. I had read some threads on a G8 forum (the LS3 uses the same tensioner) about the tensioners coming apart. I am not sure how common it is (maybe somebody will add in here) but the LS2 block style have no moving parts to fail. I reinstalled the LS2 tensioner.

I have heard rumors about them coming apart as well. However, this same tensioner is used on the ZR-1's. I am not so sure that GM would have put this piece on their $120k vette if it wasn't durable.

As far as Im concerned the General believes in them enough to run them in the trucks and this is the life blood of the company so if there were real tensioner issues Im sure we would all have heard about it and there would be recalls etc. This isnt the case at all and considering the failures i read about had pretty damn big cams I'm thinking that the spring tensioner is good to go.
And to think there are tons of LS1/6 motors still running with no tensioner at all
