Title: Stock Timing Chain Replacement
Post by: Steve Wood on July 01 2011, 01:27:48 PM

someone sent me a link regarding a stock replacement timing chain.  

This would be a good choice as it will work with the factory tensioner and be good for another 100,000 miles

sorry, double roller chains don't use the factory tensioner...ch ews them up and dumps the debris in the oil pan

Lotsa people think they need a double roller on these engines and cause themselves grief

Double rollers are meant for engines with lots of valve spring pressure.  Our cars don't normally have that issue unless using a roller cam.

I've got nearly ten years the double-roller in my LC2... I wonder what it looks like today? Hmmmm...

I didn't see a picture of it but I originally bought a roller type chain for my car but later bought a flat link style so I could re-use the stock style tensioner. I have new plastic wear parts for the tensioner. One of these days I'll change it out. Hopefully, it will be this winter. I don't take my car to the track anymore. I drive it to a couple of cruise nights and that's about it. It doesn't mean the original one won't crap out anyhow. The last nylon timing sprocket that failed on me croaked idling at a stop light so there's no guarantees.
