Hi all I bought a 99 GT last year and all I have are problems.The car is a one owner adult owned vehicle.That does not seem to make any difference all i am having is problem after problem.She has 78000 miles on her when i noticed a coolant leak at the intake manifold.I replaced it with a dorman.During the swap I saw a little engine oil on the block under the intake.I cleaned it and put it back together.At first all was great no more coolant leak.Now a week later i see oil again under the manifold on the block.It is coming from the head gasket near the thermostat housing.Not alot just a drop or so every 10 minutes.I am a mechanic for a local bus company and have the tools to change the gaskets but my question is could the head be warped and causing the leak.Is this a common problem or just me.Any info would be much appriciated.Also the exhaust bolts are all rust any suggestions on getting them off without breaking them.I think i should have kept my 88 GT.I only had half the problems. MIKE :headscratch:

not really common on these cars but it can happen, pretty much happen to any car. i don't think your head is warped, could have it checked though but due to aluminum heads on a cast iron block, the heat expansion and cooling, both are different and can wear that gasket out.

PM me your email address and remind me that you want the 4.6L PI head removal and installation procedure from Ford. I have the procedure for Ford for the the 2000 GT, but it should be identical with a few small if any differences. It should have torque sequences and ratings included.

Are you certain the leak is from the head and not the valve cover? Try testing the compression first, you may have a much simpler problem. Its possible the head is warped or cracked, but the only way to check for sure would be to have it off and check with a very good straight edge and magnaflux it.
