I just came here to hi-jack your thread, but the bold part above just hit me. If you're really, really, sure there was a bucket with no shim under it that sounds like a big dealer "oops" (make sure it's not either stuck on the head of the valve in the underside of the bucket - it could be upside-down and if you're expecting to see number etched on it and you don't...). There is no way in crap the valve clearance was acceptable with no shim in there, and that valve would have never been opening all the way. The fact that there are 2 of each per cylinder, and a shim-less bucket would still get pushed a little by the cam means it would probably run as well as you'd expect it to, concealing the problem.Zepfan said:No all the shims were under the buckets
Showed it to dealer whos done all the valve adj and of course they didn’t know.
Parts for basic cct bolts gaskets near $600.
Can someone explain the small pins on exhaust cam?
The pins strike the valve caps.
So if that pc IS a shim, I'd say the last guy who serviced it somehow left it in the head but forgot to put it under the bucket. Then it would bounce around and get chewed up. It looks like you might have a big enough pc to measure the full diameter - I don't know what diameter shims are, but someone will (they're pretty standard). The thickness would be telling, too, and if there's any vestige of a number etched on it you have the smoking gun. If not, maybe posting up the size and a good description will net some thoughts from the experts here.
