Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
Due to low oil pressure warning and a knock at startup followed by a rattle at high RPMs, I’ve decided to tear the engine apart. Prior to this I’ve already replaced the oil pump (due to low oil pressure), timing components, as well as bearings, prior to this tear down due to knocking as well. I’ve removed the camshafts, but as I was looking the intake camshaft’s guides appear to be worn really bad compared to the exhaust camshaft guides. Is this normal? Can a machine shop fix this or would buying a new head be warranted? Thanks! This is the Intake cam guide The camshaft also looks pretty worn..
