They wish! > What specifically does it mean when an engine "sucks a valve"? Mechanically, > what has happened? The head broke off one of the valves, usually the #3 exhaust. Then the piston tried to compress it into a space too small for it to fit. The piston is always destroyed. The head is usually destroyed. I have seen the opposite piston also be destroyed as well as a couple of rods and the cam. The case is usually "okay" but sometimes beat up. > More important, if I tear the engine down, what should I expect to have to > replace/repair? Head? Pistons/cylinders? Other? The usual is to just replace the pistons and cylinders, and one head, then do a valve job and replace all the exhaust valves. I have seen engines where the only salvagable parts were the generator, flywheel, pulley, fan, sheet tin and carb, but this is unusual.
