Re: Newbie thinking about diving into a '65 GMC 1000
So I ended up blowing the camshaft during break-in, despite every effort to do things by the book. I think the problem might have been waiting too long between assembling and firing it up, but who knows.
Dropped the pan and there was a bit of metal dust in the oil residue, so I cleaned out the bottom half. Checked one of the rod bearings and crank bearings and they were both fine, so I buttoned it back up. Put in a new cam and lifters, and away we go. Things seem to be good now, the oil after break-in was pretty clean, and it runs well. Still a bit noisy until it's warmed up. Not sure if that's because the rockers are a quarter turn too loose or thats just what these old engines sound like.
