Hey guys new here! Looking for a little help... Truck won't start after overheating. I didn't compression test while cold... Hence it won't start. First what are we working with... 97 Ford ranger 2.3 engine dual spark plugs. Checking compression on exhaust side. Cyl 1-65psi...cyl 2-65psi... Cyl 3-65psi cyl 4-150psi... Testwd all 3 times... First 2 times turning over 4-5 seconds. 3rd time 10 seconds. So the question is will a blown head gasket cause that low psi?? Or should I be looking at valves?
