[QUOTE="Serfma, post: 16675378, member: 196123"] '96 Cobra, ever since I've had this car I've had issues with heat. I've only gone as far as swapping head gaskets and doing my best to inspect everything head related. Valves looked good, none bent, cams on driver side looked slightly scored but nothing that stood out to me that said "This is bad!" I have replaced the following: Radiator (Mishimoto) Radiator hoses Water pump Fan (Mark 8 fan, not the most CFM moving fan, just the tier down) Fan IS shrouded and properly mounted against the radiator I have no condenser. Removed when I got it. 188* thermostat Coolant burped properly following [URL="https://www.reischeperformance.com/refill.html"]Ford 4.6L DOHC Coolant Refill & Burp Procedure by Reische Performance Products[/URL] Have only long tube headers, everything stock. EGR deleted, tuned out. (Issue present even prior to deleting EGR) When I replaced the head gaskets I did not degree the cams. It was at a time that I did not know better. I am trying to narrow down what is going on and where this heat is coming from. I know stock cams / sprockets have enough play to mess with cam timing by up to 6 degrees, can heat be from cam timing? I've thought that my rings are going bad, but I don't know if bad rings can cause excessive heat. Long term fuel trims at idle sit around 10% passenger bank, 18% or so on driver bank. Any help will be greatly appreciated. [/QUOTE]
