My Dodge Stratus 2.4l apparently got hot and the gauge did not register. I was going down the road and heard a knocking noise. Temp looked normal and had oil. I proceeded to go home and it started getting worse. It then started losing power and the entime light started flashing. I knew something was REALLY wrong so I was planning to stop in a gas station 1/4 of a mile away and get it towed home. The oil pressure light came on and It was really knocking bad. It lost its power and shut off as I was pulling in. I had it towed home and let it cool. It will not start. It just spins over very fast. 0 my 1 cyllinder had compression. But only 80 psi. I think I blew the head and head gasket. But is there likely cracked or melted pistons or rings?
