Good day to you all; i have a 1997 Galant with a 2L 24V V6engine. i noticed that there was oil on the garage floor so i checked it out, i soon found out that it was coming out from the bolt (or nuts) that holds the exhaust manifold to the cylinder head. the valve-cover gasket is fine and there was no leak from there. there seem to be no change in the engine's performance and there's no smoke coming out and no oil in the tailpipe's end. i this serious? how can i stop the oil from leaking? HELP?!
Either the cylinder head is cracked or, Is it possible that a stud had once been broken off in the hole(s) and when they were drilled out the drill went a bit to deep and punctured the cylinder head? That is about the only reason their would be oil coming out of the manifold stud holes as the holes are not connected internally to anything.

I bought a 2000 RL used, with some factory warranty remaining, and then bought an extended warranty. While hnder warranty, car began to smell up my garage from fumes from oil dripping onto hot exhaust. Not enough oil at that point to show up on garage floor. Complained to dealer about the odor but Acura Master Mechanic (said he) couldn't find source of odor (although I told him I suspected an oil leak because I had prior experience with oil leaks and resultant smells on another car). On the next service visit after the extended warranty expired, same master mechanic said my RL's rear main oil seal was leaking onto exhaust causing odor. And the dealer wanted north of $1000 to fix it. I declined. Leak has steadily gotten worse - now visible drops on garage floor. An independent repair shop quoted $650 plus the cost of replacing expensive, special Honda transmission fluid. Took my complaint all the way up the chain to the head of Honda in Japan, but got no assistance. No more Honda products for me.
Interesting. White smoke is usually burning coolant. You should be loosing a fluid, something has to be burning to make the smoke. It could be a very slight drip onto the hot exhaust manifold or pipe if it is only happening from under the hood.
YOU HAVE A LEAKING ENGINE VALVE COVER(s) GASKET(s), THE VALVE COVER IS ON THE TOP OF THE ENGINE AND COVERS THE VALVE TRAIN PARTS, IT IS THE MOST COMMON SOURCE OF LEAKS IN ANY ENGINE, THE OIL DRIPS DOWN THE VALVE COVER AND THEN BURNS ON THE EXHAUST MANIFOLD(s)
The classic signs to look for are engine over-heating with bluish-grey smoke from the exhaust pipe and it might be smoking excessively, look for coolat present in the engine oil, the engine oil will float on top of the coolant so if the engine oil is reading unusually high on the dip-stick you can loosen the engine oil drain plug just enough until it starts to drip fluid, and if that fluid is water or coolant then you might have a blown head gasket or an intake manifold leak, and if you have all of the symptoms of a head gasket without the smoke from the exhaust pipe it might just be the intake manifold.
Hi, you may have a valve cover gasket leak that is dripping on the exhaust manifold. I would inspect the valve cover area for oil spots and rim leaks. The smoke is coming from the dripping of the oil on the manifold or, lower exhaust pipe.
