KA24DE white smoke

[Lunghz]

okay so yesterday i noticed my 240 was spittin some white smoke (very little) so i took out the spark plugs to check them and noticed the number 2 plug was wet with oil, cylinders 1 & 3 also had signs of a little oil but no wet plug and cylinder 4 was fine. From what Ive researched Ive learned that it may be the gasket for the valve cover leaking causing oil to go into the cylinders. Im going to do a pressure test soon hopefully its not my rings or anything. And the car runs fine so i dont think its a head gasket.

Always has anyone had this problem or know what it might be? car only has 148k miles. any help is highly appreciated! :cj:

Usually white smoke would be the sign of burning water. Most would say its the head gasket but...I had the same problem today and noted that my car was leaking oil so I'm kinda not thinking its the head gasket because I just changed it. Pcv valve sounds cool.

Water doesn't burn. Coolant on the other hand...

Also, a metric shitton of oil will burn white.
