car still smokes

[dan2288]

Its still smoking white smoke. When you first start it up it smokes, but after 15 min of ideling most of it goes away. But then when you rev it up, a big cloud of white smoke comes out. We did a leak down test and it was good. Im gonna do a compresison test soon to see if its the head or headgasket. What else could it be ?

White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. The cylinder is where the fuel and air mixture are being compressed and burned. Any amount of antifreeze that enters this area will produce a white steam that will be present at the tailpipe area.

If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake.

Most likely headgasket

ok, so the headgasket is good. Im thinking the turbo is maybe burning oil. Even though the smoke is white, my dad says it smells like oil. Myabe the seals are bad on my brand new fp3065 ? Any way to check and see if its the turbo ?

Ive had a headache load of smoking issues also in the past.

Normally
black smoke- fuel
white smoke- water/coolant
gray smoke- oil burning off/inside exhaust- valve stem seals
blueish smoke- oil burning in combustion chamber.


What your describing could be valve stem seals more likely than turbo seals especially if the turbo is new, but the compression test will at least give you a clue to whether or not its the rings....

Very thin, light white smoke can still be oil like on a 2-stroke, but you said a huge cloud of white smoke which is definitely coolant.

Do a leak down test to be sure
