Well, I have an 89 GT with jus over 100,000 miles on it. The problem is when the engine runs for a while, i can literally fog the entire road up with white smoke out the exhaust, its horrible. I checked the oil and its way past full and mixed with water. Does this mean a blown head gasket? If so, when i go to put head gaskets on, is there any type of sealer i should use like rtv or something? How about on the intake, any sealers besides gasket? Thanks.

Yup, The head gasket is the problem! And no you dont need to use any seelant on anything. But you can use a gasket adhesive to help hold the intake gasket in place, I belive 3M makes this stuff called weather stripping and gasket adhesive, it looks like snot and it works great. And make sure you get new head bolts, you cant re-use the stockers because they are tourqe-to-yeild.

you buy a set of fel-pro hg and do away with the steel one...

and make sure any sealant you use is oxygen sensor friendly or you will kill the O2 sensors and have to replace them too. don't use the stock intake gaskets for the two ends, use a smooth 1/4" bead of gasket maker and run a continuous bead from one head over to the other along the block surface that the intake seals on. let it sit about 10 minutes to get tacky so it don't all squeeze out into the lifter valley and you will get a better no leak seal than you would using the gaskets. use the regular intake gaskets on the port sides and you will be fine without any other sealers on them although a dab or two here and there to help hold them in place don't hurt.
