Hey guys just got the car last month..my car started smoking yesterday on left side of the engine..below the belt i believe cant find the source. and my oil pressure gauge drops now to 10 psi...its hooked up to galley port..did oil change still smokes,smells bad.i was thinking oil pump? srry for errors currently on phone.

 

any1? it also makes a grinding noise when i hit gas pedal here and there

 

Are you leaking any oil? Bad pump shouldnt cause smoke as far as I know. How many miles are on the car, and are you the original owner?

 

no leaking oil..105k and no i am not the original

 

what kind of grinding noise? Does it happen when the car is parked and revved?



What color is the smoke?



Try taking video of the noise or smoke.

 

1) Is smoke coming out of your tail pipe?

2) The water pump is in that area, is the car hot when this "smoke" appears?

3) are you finding your coolant low, could be hot coolant vapor ascaping.

 

Just saw the 10psi oil pressure thing, could be the oil pump, lets hope. Does the psi drop after it warms or is it at 10 psi when started cold. Now I said "lets hope" cause my moms Firebird had the low oil psi in idle once it warmed up, revving brought the pressure up a bit, about to 20 psi. It has bad rod bearings

 

like pinging

Yes

smoke is white





Yes smoke comes out of the tail pipe at idle

Car is Hot when smoke appears

had a coolant leak in a hose but fixed it







when started jumps to 55-60...Psi drops after warming or driving around the neighborhood for like 5-10mins

 

Bad valve seals typically smoke when motor is started.

Bad piston rings smoke when motor is running.

Pull your spark plugs and see if one of them is different than the others, could have a cracked ring.

Do you see any contaimination in the oil? Like water/antifreeze? It usually shows up as muddy brown color, if so could be a bad head gasket/cracked head.

Does the smoke out the tailpipe disappear when it comes out like steam or does it hang around and stink like burnt oil?

Does it smoke more when your driving it or only at an idle?

These are tough to guess at if you can't see it doing it first hand.

 

Ill check the plugs when I get back from Dc..but when I fixed my coolant leak.the tank is a muddy color but I flushed it and replaced it.



And my oil looks good but I was also down 2 qts



The smoke out of tailpipe steams..but I did the paper test and spots of oil show up when the paper is held towards the smoke..and it smokes more at idle not driving



Srry for the questions..I kno a lil more then basic about cars but still learning from this site and books..after this fix ill post pics up and my future plans
