well this question is for my 1990 Pathfinder which basicily has a identical VG in it as our maximas, but recently it has been smoking from under the hood and i found out its coming from the manifold and there is a big black spot on it. Do you guys know of any place where oil or any other fluids could be leaking onto the manifold and be causing the smoke ?

 

What manifold? Exhaust or intake?

 

sorry, the exhaust

 

Exhaust manifold. Maybe the gaskets are faulty or too old.

 

Probably just the valve cover gasket.

 

Ok. Now eh have approached the either of two exhausts...

Netx def: frontex, rearex ... left, right ... top, bottom ? ? ?

Q.: How about gettin an indian mech to trblshoot the billowing smoke sigNal codes?

 

crack in ex manifold?
busted studs?

the black is the soot/carbon from the exhaust gas.

 

it is the right manifold if you are facing the front of the vehicle i might get a picture later but i think it might be a valve gasket to but i wouldnt mind if you guys had any other ideas. And also when i said black spot its definetly not just carbon from a exhaust leak, it actually looks like a burn mark and it looks like burnt oil and the oil level is fine. So maybe its some other fluid?
