Severe oil leak


It could be a bad oil pressure sending unit, valve cover gasket, timing chain cover gasket or oil pan gasket. If there's white smoke coming out of the exhaust it could have a blown head gasket but it's not a common problem with that engine.

I have a Z24 Cavalier and theres white smoke coming out the exhaust and timing chain makes a lil rattle noise when I first start it in the morning and tends to stall until it reaches the temp of 165ish...


So if it's not consuming oil and you are SURE to fill the radiator to PROVE it's not burning coolant ... then the other suspects are head gasket and .... A puff of smoke upon start-up could be caused by valve guide seals allowing some oil to leak down into the cylinders while the car is parked and not running. This would be pretty common on a nine year old car and should not, in most cases, be cause for concern - See more at: http://community.cartalk.com/discussion/2280708/white-smoke-from-exhaust-upon-cold-start#sthash.05fuptIx.dpuf

If it's blue-white then What you might be seeing is oil burn-off from leaking valve guide seals. The next time you have the oil/filter changed, have a high mileage oil installed. - See more at: http://community.cartalk.com/discussion/2294478/white-smoke-coming-from-the-tail-pipe#sthash.jVo0zDhw.dpuf

2004 gmc yukon lite came on low oil pressure just had oil change 5 days ago checked it was low about a qt. Has 157,000 miles what can be the cause


There can be alot of causes, such as valve covers leaking, oil pan gasket leaking, oil filter leaking, rear main seal leaking, front timing chain cover seal or gasket leaking even bad rings. Does it smoke out of the back? Your valve seals could be leaking. Best way to find out if you have a leak is to inspect the valve covers manually, or take newspapers and lay them under the entire engine on the ground, and it will leave the tell tale stain of a leak. Hope this helps.

OIL SMOKE AFTER MAKING CORNER TURN.


two things Is the oil overfilled? Has the oil been changed recently enough? A fuel injector leak can put alot of gas in the oil. The valve covers may not be draining back to the crank case. The oil cap off just after its been running it shouldn't be full of oil. The oil stick may not be right, and the oil may need to be changed and only put in the right amount(5 quarts with the filter) and then run the car and then check the oil with the stick to see if the stick is right. I'm guessing that the oil smoke is coming out the tailpipe? Ifit's comingout from underthe hood then the motormounts may be broken enough to let the motor hit the belts to the engine bay side or the timing chain (worn out is grinding thoughthe timing chain cover and the oils coming out ( this usally takes alot of miles and many missed oil changes.

check your spark plug wells for oil build up. A BIG problem with the early saturn's are related to the rubber valve cover gaskets the go around the spark plug wells. I have changed dozens that just ware out.

Smoke comes from around engine


Probably a vavle cover gasket leak, small but enought to produce oil, in or on the surface of the motor doesnt take much to a lil smoke from aa hot engine...it could be collectiing in the canals ontop of the motor where the vlave covers sit on the head? or a head gasket problem....inspect it well after you run the car for a lil while, b4 it starts to smoke
