I would say neither as constant oil smoke is a sign of oil ring failure or broken rings that have scored the bore.. Keep an eye on the oil level as oil smoke is not a good indication of consumption as a very small amount makes a lot of smoke.

SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

SOURCE: white, blue smoke from exhaust

sorry to spoil your day but white exhaust indicates that you have a blown head gasket or the head and/or the block is cracked

you have bad valve seals again and it is possible that the valve guides are bad ( to much play ) i worked for Jaguar 13 years and i have done 100's of these and very few needed guides it sound like the seals where not done correctly at the last repair.

The blue smoke exhaust is oil burning in the cylinders, probably rings and / or valve guides. The oil around the timing belt is a gasket or seal. Its possible the exhaust smoke is a PCV valve or other venting problem.
If it is the rings or valves, and depending on the mileage on the car, you may need to have the engine rebuilt at some point in time.
And that decision would depend on the value of the car.
A used engine may not be much better for the money unless you can find one with less than 100,000 miles on it.

I have a 1997 Mitsubishi eclipse and we see white smoke coming from the exhaust every gage is fine no check engine lights no codes come up no lights period it smells like oil but no leaks anywhere we can...


If this car is turbocharged the turbo seal is likely leaking oil into the engine intake runners. The other cause is worn valve guides and seals on the valve stems for oil control.

Blue smoke from my cherokee at 210 degrees


Hi there:
I suspect it is a exhaust valve guide problem. When an exhaust guide is loose in the engine or leaking oil, the oil never enters the combustion chamber. Oil drops through the guide and into the exhaust port of the head. The exhaust stream then carries the unburnded oil out to the exhaust. As the exhaust system warms up, the oil then burns off and leaves as blue smoke.

Remove the valve cover and take a flashlight and closely look at all the valve seals and guides, especially the exhaust guides and seals.

2012 250 etec. Excess oil coming out of the exhaust ports


Run the engine for several minutes at idle. Turn the engine off and let it sit for about 15 minutes. Restart the engine and immediately increase the engine speed while observing the exhaust. If a heavy billow of bluish smoke is exhausted then disappears and the exhaust remains relatively clean, the most likely cause is excessive valve guide wear. In this case, the valve guides or valve guide seals require service. If the above test only produces mild smoke and the smoke remains at the same level during all operating conditions, the piston rings will have to be tested. This is done by performing a compression test on the engine. The first test is referred to as a "dry test" and the second test is referred to as a "wet test". The dry test consists of measuring the engines compression using a compression tester installed in the spark plug hole and the ignition system disabled. The engine is then cranked and the pressure is measured and recorded. A few teaspoons full of oil is then poured into the spark plug hole and the compression is then measured again. If the reading increases more than 15 PSI, the rings are worn and major engine service is probably required.

Smoke from exhaust


White smoke is from water in exhaust, usually a blown head gasket

Blue smoke is oil in exhaust, usually rings, valve seal or valve guide wear

Black smoke is a rich fuel condition.

Blue smokes come out tailpipe when i start the car but stops afte


Helllo there
Symptom: Gray or blue smoke from the exhaust. You notice gray smoke coming from the exhaust when you start your car. The smoke may or may not disappear after the car is warmed. If it is, it is less noticeable. The smoke may have a bluish tint to it. Possible causes:

  1. The engine's piston rings may be worn.
    The Fix: Replace piston rings. (Generally not a DIY job)
  2. The engine's valve seals may be worn.
    The Fix: Replace valve seals. (Generally not a DIY job)
  3. Damaged or worn valve guides.
    The Fix: Replace valve guides. (Not a DIY job)
Symptom: Engine uses more oil than normal, and there is some smoke from the exhaust. The oil level is low between oil changes. It appears that the oil is being burned by the engine because of the smoke in the exhaust. You may or may not notice the engine doesn't have the same power as it used to.
Possible causes:

  1. The PCV system is not working properly.
    The Fix: Replace PCV valve.
  2. The engine may have mechanical problems.
    The Fix: Check compression to determine engine condition.
  3. The engine's piston rings may be worn.
    The Fix: Replace piston rings. (Generally not a DIY job)
  4. The engine's valve seals may be worn.
    The Fix: Replace valve seals. (Generally not a DIY job)

Reset check engin light


White smoke from exhaust indicates burning coolant. Blue smoke from the exhaust indicates burning oil. In replacing the valve cover gasket for an oil leak, some smoke from residual oil is normal but it would be excess oil burning off on the manifold from the engine compartment, not the exhaust. Hope this helps with your question.
