You have coolant getting mixed in with the oil. The head gasket and intake manifold gasket would be your most likely culprits.
Water in the oil! lack of power and foam on the dip stick or white smoke: Head gasket?No loss of power lots of foam, gets hot rainbow on the water surface: crack in the engine or head? ouch!
piston rings going bad oil leaking around to top of piston so when you start the oil will burn white
probably moisture, not good Oil level over full
oil getting by the rings causes white smoke and oil dripping out of the tailpipe.
short trips oil not getting up to temp
If you have too much oil in your pan there is a possibility that the crank will whip it up into a foam. Your oil pump will no pump the foam so your engine will not get the lubrication it needs. No lubrication = seized engine.
You probably have a cracked engine block and engine coolant is mixing with engine oil.
Yes.having low or no oil causes friction in the pistons which will cause car 2overheat.
White smoke normally means you are burning oil.
an oil pan leak is adding oil to the already polluted environment, causes you to drive with your car a bit low on oil at times, and causes unsightly stains under the car .aside from all this if you monitor the oil level and keep it where it should be , not much of anything else ,i can think of,
Water in combustion chamber-common sign of bad head gasket especially if recently overheated. Oil will probably have water present in it and easily apparent.
No, but it is not good for the engine to fill it up beyond the full or safe mark on the dipstick. If the level of oil reaches the rotating crankshaft, the oil will get whipped into a foam and decrease it's ability to lubricate.
