you must be talking about hte cams gear teeth - and to me that sounds almost impossible???

thats like 2mm of steel, and a fancy complicated geometric design that should be very strong!!!

so i would've assumed that the chain would break first!!! :shock: :shock: :shock:

it's a friend of mine's s14.took it to get it dyno'd @ snail conversions.the guy there said the chain is to tight and put in another chain tensioner,also took out the cas.when they started it again it made one moer of a noise and he said it's faulty lifters. my friend phoned me and a removed the tappet cover to find the teeth broken.about 10-12 of them around the sprocket.
