That is the video I took of white smoke coming from my engine, not from the exhaust. What could be the cause and what can I do to fix it? I've just changed the spark plugs, rear o2 sensors, and valve cover gaskets on the driver's side. The gaskets I changed because one spark plug was drowning in oil when I checked it.

 

Similar problem I'm experiencing right now... Valve cover gaskets are new from last June, haven't changed my o2 or plugs, but have the same burning problem. Too d*mn cold to really do much work where I am but I've heard several possible issues including the PCV system to as bad as a cracked head gasket... I also have an issue with the SAI vacuum lines.

 

Well I've got the rest of the heat gasket set, but I only changed the ones for the valve cover because a spark plug was practically drowning in oil there. So what you're telling me is I might have to change all the gaskets?

 

Does it do that when the engine's been run for a while (at least 30 minutes)? It seems like it could just be condensation boiling out of the oil.

 

^This was the other possibility I've ran into, personally mine stops smoking/smelling after the car has ran for awhile, although the oil temp never gets above ~175-200F in this weather (even after a 4+ hour drive last weekend...)

 

I haven't driven it, it's still up on stand but I have left it on and let it idle for more than enough time for it to reach normal operating temperature and it still did that. And after some time the white smoke come out if somewhere else and I don't know where. At first I thought that I didn't put the gallery on properly, but I checked and the nuts are very secure and I even checked the spark plugs to see if the had oil on them ( the reason I changed the gaskets) but they were just fine.

 

It takes more than a couple minutes to boil off water in the oil, that's why i said at least 30 minutes. You need to go for a drive to bring oil up to temp, and then keep driving. Do you also get white-yellow slime on your oil cap and in your breather tubes?

 

It's definately moisture boiling off. This is why it's important to always get your vehicle up to operating temperature when you drive. Not just fire it up, slap it in gear and drive for 3 min and shut it off for weeks on end.
