i dont know where it came from but it sure made a mess its even against firewall and it even reached the vac tree its all covered in oil , like if something when i accel hard made a liquid squirt out i already took of valve cover and re tightened them down. Could maybe a bad oil pan gasket do this or my brake booster probably had to much pressure and squirted out liquid, im confused

You won't lose oil from under a head gasket. There is no oil pressure in the head. It comes up the pushrods into the rockers and drains down the oil return holes in the heads. If it is over heating (prob due to low coolant) the first place I would look would be the intake. if the intake is loose you could loose oil out of the back and coolant at the back of the intake

isnt there an oil galley plug under the intake that can come out

There's no oil passages on the outside of the head/block interface. Pressurized oil comes up through the push rods, then drains back through the lifter galley.

Any oil leak on the front of the engine will travel along the head gasket seam, and then drip down the side and rear of the block.

The most common site of a leak would be the valve covers. I'd start there. Also take a look at the front of the intake manifold to block seal, and the distributer O-ring.

There is a plug in the block under the intake manifold, it's in the rear. If that comes out or leaks, it will leak into the lifter galley. You won't see it, but you'll have a loss of pressure.

If you are heating up at red lights, but not while driving down the highway.... your radiator fan is ****ed

x2 you prob need a new fan clutch


and it could be leaky valve cover gaskets or bad lower intake gasket
