I have a rattle in my engine, wouldn't call it a knock. It's too fast for a rod or piston knock I think, too loud and low toned for valve play (not clacking), sounds high and forward on the engine. Oil pressure is excellent, didn't react to adjusting the timing at all (it was retarded). If it were a higher pitched noise, I'd be thinking a valve play.
Any common known issues that cause this sort of sound on these engines? Can the water pump or the governor make this sort of sound? Any ideas before I start tearing the engine apart?
