[QUOTE="helio lucas, post: 1407785, member: 78346"] for the unit price is better to not re-use old head gaskets (you might get away with it but i didn´t said so, nor i ever have done it ;) ). if you have the cylinder out you can visually inspect it. you have to do it anyway after the leak down test. if the leak is in the gasket you will see some discoloration at the head or cylinder face, darker grey, maybe slightly brown. if there is no leak search the head, most of the cracks happens around the studs. next, the cylinder. the crack could not be at the exhaust duct, maybe on the bore. ------one thing i almost forget, the base gasket seals not only the cylinder and crankcase but a water duct from the pump as well. if the gasket or the surface leaks the water enters the cylinder and goes out on exhaust. (the engine is a air pump right?)------ --edit-- after posting i start to get some doubts and confirmed that the cr80 had no duct but a external pipe instead. i apologise for being dumb :cool: --- [/QUOTE]
