Driving my Cobra to my brother's place about 5 miles away. 3/4 of the way my A/C starts to blow warmer air. I get to my brother's and shut the car off. Later in the day I leave, with the A/C off. About 2 miles away I turn it on, it starts to get cold then stops. At this point I finally think to look at the temp gauge. It is climbing. As I get home the temp gauge is a needle from hot. This has happened before and I ended up changing the rad fan, 6 mos ago. So I make a call to a local shop. I bring it in on Friday, today. They call me about 4:00 today and tell me they did a pressure test of some type on the engine and it failed a couple times. The diagnosis, either a blown head gasket or 2, or a cracked head, if nothing else is wrong. They can't tell till I give them the ok to tear into it. Which btw, they are saying it will be about close to $4000.00 to do the job. This would include, removing the engine, removing the front for the timing stuff, then removing the heads. Then pressure checking the heads for cracks and also for warp-age. Changing the gaskets and dealing with whatever else, (replacing head, etc. then reassembly, and reinstall back in the car. They don't want to shave the heads because that might be a problem if the head is warped. Could cause internals to freeze up later. I was also told by another guy, former termi owner, owns a GT500 now, that Termis don't normally blow head gaskets. So I guess that means I need to hope for a head crack. Anyone have some advice on this? This is my daily and I want it back on the road. What should I do, help please..
