Why is my car losing oil?


Hi..That is a lot of oil you are losing, The engine is definitely toast.
Blue/Gray Smoke: Blue/gray exhaust smoke is an indication of oil burning in the combustion chamber.

Valve Guides: Excessive clearance between the valve stem and the valve guide allows oil to leak past the gap into the cylinder.
Piston Rings: Worn or damaged piston rings will cause blow-by resulting in blue/gray smoke.
Worn Cylinder Walls: Worn cylinder walls cause blow-by resulting in blue/gray smoke.
PCV System: A stuck closed PCV valve will cause excessive crankcase pressure resulting in blue/gray smoke.
Is it worth fixing? Depends on how much this car means to you, Mileage of vehicle, and just how much money you want to throw into a 20 year old car..The engine will need to be completely overhauled or change out with a used engine probably close to 800- $1000 either way..Probably have a lot more into this than you can live with I'm guessing

My 2001 xj cherokee TD blows excessive smoke when the engine is under pressure.


Sounds like a broken oil ring. As far as the engine stalling, if your really low on oil the motor will shut down so as not to damage any bearings and other internal parts. Does the engine seem to be turning over faster and taking longer to start than usual and take a little longer to stop when you turn the engine off. If so you could have an issue with the compression rings in one or more cylinders. Do a compression test. If the #s are near where they should be it's likley oil rings. If the #s are low it's likley the compression rings. Either way if its one of those issues you'll need to overhaul your engine

1997 mazda e2000 van which is blowing black smoke


if it takes 5-10 mins of running before black smoke disappear i think you could have broken rings causing engine oil into the combustion chamber. you could observe white smoke if you have just changed oil.
solution would be to replace piston rings. it would save u a lot if u could diy.

1991 Honda Accord, 213k, changed oily sparkplugs and now engine blows excessive smoke and oil continuously out the exaust from start up to shut down.


Old spark plugs were likely fouled with oil and not burning fuel (and oil) completely so minimal smoke before change out. New plugs are clean and burning everything in cylinders well including oil (therefore more smoke). If smoke from exhaust is blue, then engine oil is getting into cylinders either through worn out piston rings, or a leaking gasket. If black smoke, then this is a sign of too much fuel getting into cylinders and not all the fuel is getting burnt during combustion (a fuel system problem).
