Oil can enter the combustion chamber in at least 3 ways:
1. Worn piston rings may allow oil to come past the piston from the crankcase (continuous smoke). This condition is often accompanied by blow by, where exhaust is spilling into the crankcase and can be seen passing out the oil dipstick.
2. Worn valve guides can allow oil to come thru the valve openings (usually a puff of smoke at startup)
3. A blown head gasket (or cracked head) can allow oil to flow from the oil passage to the combustion chamber.

Will only stay running on revs over 2000rpm if I take foot of peddle it cuts out also white smoke from exhaust


What is year--make--model?
Are you losing coolant? The white smoke may be coolant in the combustion cylinder, possibly caused by a head gasket problem. If head gasket problem, fix that first.

With idle issues, clean/check anything that has to do with idle air system. Any applicable trouble codes?

Engine was knocking but running good not smoking so we replaced the engine with brand new short block from Toyota. Now the truck is blowing white smoke. What could the tech done wrong to cause this? Or...


Take it back. I doubt the short block is bad, but if the smoke persists beyond a day or two, the cylinder head may need removing to check the fit of the head gasket, and to ensure the passages in the head match the block. Does the exhaust have a sweet smell? That could be coolant burning.

Now it is possible that a little spilled coolant may have collected in the exhaust during the engine swap, and that is why you see white smoke. This should burn off in a day or two. If the smoke persists, and the coolant level is dropping, they need to take it back and fix it, at their expense, at least the labor charge. Toyota may have made production changes during the year on this engine, and that is what needs to be investigated. That, and if the head gasket is correctly fitted.

Why is my 2000 kia sephia blowing blue smoke from the tailpipe. it has 86,000 miles. the check oil warning light is on even though the dipstick reads full.


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.

Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.

Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

If your not overheating or losing coolant, its more than likely engine oil burning. If it is coolant related, possible blown head gasket.
