I found that a PO had not only replaced some valve cover bolts with regular (and, wrong-threaded) bolts, they cracked one of the cam holders - I suspect by forcing in the wrong bolt.The Jimbonaut said:Also discovered that at least one of the valve cover bolts has stripped the threads in the head. Time for more TimeSert shopping?
I'd get all the flaking crap off and see what it looks like. If you have chipped spots they will need to be sanded down and blended or you'll see them in the paint. You'd probably only notice it in the flatter areas like side covers, the top of the cases etc. If its really bad you may want to remove all the paint with aircraft stripper or other paint stripper, just be sure its safe for aluminum.The Jimbonaut said:That was the plan mate - pull off the side covers (plus the oil filter cover, valve cover, starter motor cover and a few others), mask the thing up and have at it. The engine's been painted before - do I need to get all that paint off first, or is it enough to rub down the rough spots, knock off the loose stuff, hit everything with primer and then the VHT?
