I got to looking closer at the timing chain and sprockets, cam, & crank. The cam is where it should be, mark on sprocket lines up with arrow on bearing cover. The roter points to #1 wire. But, when I turn the crank with a socket wrench, the timing mark on the crank pulley can move from 5 degrees before to 5 degrees after top dead center without ever moving the cam sprocket. Now that seems to me to be alot of slop in the timing mechanism. Timing chain & sprockets were replaced, presumably, 80k ago when I swapped out the original motor for a Jasper crate motor. Time for new timing chain & sprocket? If so,what else do I replace? Crank sprocket? Cover--didn't I read they are often worn nearly through? Guides (or whatever you call them, the rails that keep the chain tight and from slopping against the cover). Aren't there some kind of aftermarket ones that don't wear out as fast? Is there a kit I can get for the whole shebang? <img src="/forums/images/graemlins/smile.gif" alt="" />
