no stethoscope here, i have tried using the end of a long screwdriver, against the engine, but all i hear is the orchestra, i cant pick out the trumpet player!! well, i guess it sounds like a bearing, and it does actually sound like the engine is going to grenade, so the cover is coming off tomorrow, and i will check all rollers, and especially the water pump bearing/ shaft.
thanks for the info guys.
