LS2 timing chain tensioner block

Post by White Stripe »

I have a gen3 lq4 block. It doesn't have any type of tensioner. Will adding a ls2 chain block make a difference? I read a brief mention about preventing excessive sprocket wrap but not sure if that's a real issue. Will the ls2 chain block provide any benefits?

Are you sure your block has provisions to bolt a dampener or tensioner to? If so....I would put one on it. Hell I like to use the tensioners, that everyone else discards. The Gen V tensioner is interchangeable, 12630107. I have used it on several Gen IV's, manufactured by Cloyes. I haven't had any issues personally with the Gen IV tensioner either 12626407.

If it has the place to bolt one one, Id put something on it. I get the appeal of the dampener 12588670, ....no moving parts.

I added the dampener. I drilled the holes in the block to add it. I figured it would reduce chain slap and help it last longer. But I was just guessing on that. I was afraid of the tensioner because of the added complexity,
