RH upgraded Cam tensioner impressions - Page 3 - ZR-1 Net Registry Forums

While I was out of town over the last three weeks TDY I had the ZFDOC install a new RH Cam tensioner upgrade kit. As discussed here. Pic below was taken from this thread the upgrade consisted of an aluminum housing that collected more oil. Note that the tensioner in the kit comes "loaded" or compressed.

While I know its "normal" for some of our cars to be a little rattlely at start up... to me.... it was just plain unnerving. My car would sound like the cams on the passenger side were going to fly out of it. I can tell you this is a outstanding upgrade to get if your car is doing the same thing. If you look at the above post you can see pics posted up on the differences.

I know GM would never call this chain rattle a defect just like those famous Multech MY 90 Fuel injectors however my hats off to the engineer who resolved the problem by allowing more oil to be cupped in order to remove almost ALL ofthe rattle. My results were fantastic and I highly reccomend getting this kit. The kit is pricey but it includes a brand new tensoner as well so.... Your mileage may vary. I highly recommend this mod. GC out
