Ok the common household Razor blade is .010" thick and you need like .003"-.004" your off by a mile, but that does Not matter because you have suffered a Major Internal failure. The engine was locked up and you simply freed it up, that did Not solve what caused the engine to lock up to begin with, one Must find and Fix that problem. Honestly you do not have the tools and knowhow so your best course of action would be to buy a complete new engine and install. cuz yo can jack with what you have forever but she aint never gunna run the way it is..
That Grinding Noise is Yelling at you that she is all over, sounding more and more like the lower end crank bearings are junk and came apart and knocked the cam chain off.
good luck..

Pistonguy: "I was hoping you would Not take Grumpys advice and Not tear into the engine because your in real trouble now. The guy with three posts sends a young kid down the road to ruin in one post just plane Boils me.."
Well, realizing this is an old post, you sure are full of yourself. His problem, as related, was indeed discovered by taking the rocker/cam cover off.
Just what did I send to ruin? The problem was there from the first post, all that happened was that Marty discovered exactly what it was.
It was stated he could not rotate the crankshaft. Given that, looking at the valve train was, in my mind anyway, a lot simpler than taking the whole thing apart. Four (some have more) fasteners to remove the cover is not really tearing into the engine, and taking things apart is how you learn.
I have been fooling with engines for a long time. I try to pass on some of my knowledge and experience. I may have only a few posts on this site, but have thousands on a lot of other sites.
Thank you for posting, but I disagree. I hope he figured things out. He likely has a bent/damaged sprocket on the crankshaft that the chain got into when it came off the cam sprocket and jammed. But, given it is from a year ago, and no more posts, we'll likely never know.
