It sucks. We had an issue with it not wanting to start. Turned out the injectors were gummed up pretty bad. But we had quite a bit of cranking time on the motor, sucks to think that every time I was cranking it over I was destroying the motor.
Got the new injectors in and it fired right up, heard a slight tapping noise. Put an oil gauge on it and had 60 pounds at a fast idle, started pulling plugs as the noise got more noticeable, nothing made a difference. Had a couple of my friends come over to listen to it and it blew when I cranked it.
Something in the cylinder was the last thing on my mind. My head was thinking rod bearing, bad lifter. Huge kick in the pants.
