Good day everyone. I just purchased a 1997 Accord DX. It had a pool of oil in all the spark plug wells, I mean a pool. So i changed the valve cover gasket, upper and lower well gaskets. While i was under the hood I changed the plugs, wires, dis cap, rotor, and oil.

Upon start up a crap load of white smoke continuously puffed out the tail pipe. I thought nothing of it because all the oil dripped down to the combustion chamber. So I figured I should leave it on and even drive it to burn it off.

Well it's been on for an hour, drove for 30 mins and smoke is still there. Oil level is spot on, and car is not overheating and no coolant loss.

Does it take that long to burn off oil? Any ideas?

 

Is it white smoke or steam? Where do you live, is it cold outside?

White smoke usually means water/coolant burning in the combustion chamber/exhaust.

Grey/blue smoke is more along the lines of burning oil.

Does the exhaust have a smell to it, not that I am asking you to stick your face right in the gasses. But if it has a sweet smell, similar to a cedar tree, then it is glycol, antifreeze. Burning oil has a more bitter smell to it.

If it has no smell and you are in a cooler climate, it could just be steam. H2O (water) in the exhaust can be found in both a gas (steam) and liquid (condensate) state. This is a natural result of the combustion process. Let your engine warm up and the exhaust get up to temperature. If it dissipates than it was probably more than likely a bit of moisture in the exhaust pipes.

 

I owned a 98 BMW that did that, poured out white smoke, but no codes, good compression, oil and coolant seemed fine all the time.
Ended up being a crack in the cylinder head that led from cooling jacket right into exhaust port.




If it doesn't clear up relatively soon, maybe something to consider.....

 

Easy way to check for internal coolant leaks/cracks is to do a pressure test on the cooling system. In my opinion it is better tested with a warm engine. As some times leaks/cracks don't raise their ugly heads until after everything has heated up and expanded.

 

Thanks for the input guys. I will try n do comp test on block n pressure test the cooling system. I'm trying to fix an oil leak on d pan.
