Changed the cylinder head. Update
I changed the head on my 87 jx. It was smoking from burned stem seals. I replaced all of the gaskets and sealed everything tight. When started finally I have no power, and a horrible racket from the head. I have tried rotating the camshaft 180 and 360 degrees (did not index cam on install) but every time I start it same deal. I've tried TDC feom #4 and #1 but the same thing every time. Noisy and no power. What next? Where to start over from?
I must have taken the front of the engine apart 10 times! Was frustrated and mad. Sat down to read the book again, "after you adjust the first four valves at TDC, turn the crank and adjust the other four" I was watching the cam sprocket turn 1 full turn, the crank sproket turns 2 times for every 1 360 turn of the cam. Once I realized my boneheaded mistake, I readjusted and buttoned everything back up and Presto!, it runs again! Thanks for the advice everyone who responded, it all made me think harder.
