Hey guys, so heres the story: A few months ago my 97 Cobra overheated, I wasn't sure why but it was puking coolant out of the overflow tank. So I started with the small stuff and replaced them. List of new parts this past year- OEM Radiator cap (tried 3 different types and OEM ran the best) OEM Thermostat (tried this also 3 different types and OEM ran the best) OEM Waterpump All Hoses New Belt Spark Plugs Mishimoto Radiator Canton Overflow tank & properly burped the air out of the system over a MILLION times Oil and coolant both look fine, fan works, and thermostat works. The biggest symptom is that I have a ton of white smoke coming out of my exhaust, sometimes more on the drivers side. My gauge also indicates (sometimes) that when I would start the car and drive to work (which is less than 5 miles away) the gauge would stay cold, then shoot all the way up past the "L" on Normal, then would shoot back down to the middle. And occasionally coolant would spew out of the overflow tank. This happens in both city traffic and on the freeway, but while on the freeway the gauge shoots back down to normal faster. Here is the video of when it first began happening: https://www.youtube.com/watch?v=R3xWgm5nMc0 The white has gotten a bit worse this past week, and after all of my hours of troubling shooting it I finally took it to my mechanic. He did a compression test and the compression was fine. He said the labor would cost at least $1800. I decided I was going to do it myself because that price a way too high for me, I'm working full time and going to school. This is truly heartbreaking because I love my car and have owned a few mustangs in the past, but have never had this problem. I have spent countless hours researching about the removal/installation of cylinder heads, gaskets, but I am by no means a professional mechanic at all. I have done simple jobs like replace the radiator, waterpump, belt, oil, cooling system, shocks/struts, etc. I have a Haynes and Chilton manual, along with my computer to help me out. Here are a few questions I'm having with before I tackle on this job: -the drivers side cylinder head is in such a tight space because of the brake master cylinder -both camshaft timing chain removal/install (i was planning on marking the teeth, so I wouldn't ruin any timing) -is the removal of the exhaust manifolds required? How have you guys handled these issues? If you guys can send me any tips or pointers I would really appreciate it. Thanks!!
