If it were the head gasket, wouldn't it run really hot and overheat?

The drip is coming from the header/head pipe coupling and it is black... Which I guess means fuel

if your mechanic "changed" the oil after it dumped fuel into the block it should not be a problem. if it were me i would change the oil again and check it for gas. also i recommend that you do what Matt1981CJ7 described and work from there.

Only in America do you have the God given right to be loudly opinionated about something that you are completly ignorant of.

It's quite normal for the exhaust to drip, or spray, a little liquid when warming up. That is just condensation that develops as the system cools down being forced out. Often times it will have black sooty deposits in it, if your exhaust system is old. The drip/spray should go away in just a few seconds as the pipes heat up.

As for over-heating, I think it depends on the size of the leak. Yes, a major head gasket failure will cause over-heating, a small leak may not.

Have you even pulled the plugs to see what they look like?

My first jeep did this. Turns out the breather hose for the T400 was hooked to vacuum. Tranny fluid = white smoke

I guess there are major problems... Oil coming out from exhaust along with the smoke, and the spark plugs are black. What went wrong with my rebuild?

I would not touch another thing until you talk to the mechanic that did the work. The more you investigate yourself, the more you give the mechanic leverage for denial.

I'll almost garuntee it's the gasket. Like I said my brothers head gasket went south because when he bolted it down he forgot to tourqe it and it was fresh rebuild also. I would be making the rebuilder repair it and dont't take it back until it's repaird properly. If the water gets in the oil it will wash the bearings and then it will need another rebuild.

Its's a project for now needs more parts and money.

THAT, is a question for the "mechanic" that did the work for you. As said, don't touch a thing and take it straight back to them.

Either wrong or completely fubared valve seals could be a pretty strong possibility.

The guys are right, though. Stop right there or he might pull some d-bag move and say "well, you tinkered with it so... blah blah blah".

Oh good. Let's hope it's something simple like a bad valve seal/s.

Good luck with it!
