I. I have a 2000 Blazer 4X4 LT with a knocking motor (it sounds like a little man is in the motor with a sledge hammer). Can anyone let me know if there is anyway to tell what's the problem simply by listening to the car run? There are no fluids leaking on the ground and the oil is ok (full and not gummy).
II. If I can't tell just by listening, what do I need to do to make sure what the problem is?
III. Would my 1996 4X4 LT motor simply swap places with the 2000 LT Blazer?
Thanks in advance,
