smoke coming out of dipstick tube?

[Amazin' Wasian]

The other day I fouled out a spark plug. Today I replaced them and I noticed there was smoke coming out of my dipstick tube and also I run my pcv and breather on my valve cover to the ground and there is also smoke coming out of those tubes...its a lot of smoke. Any ideas what would cause this? My car seams to be running ok.

*edit* I pulled my spark plug out of cylinder 2. (Because it sounded like I was running on 3 cyllinders again) the plug was covered in oil. I replaced just to see what would happen, same thing. I looked down in the hole and didn't visually see any oil. But a nice black film on top of my piston... I'm not 100% sure what all this means, bad rings? Another thing is when I pulled the plugs the first time there was no oil on the fouled plug...it was just burnt

Compression test, both dry and wet.

Alright oldman the results are in and lets just say that the results arnt that great....
This is going from left to right
126
135
10
90
I did a wet test on the cylinder with 10 psi and it only went up to about 27.. So what's going on here? Could this be my head gasket? Lots of white smoke and I noticed on my way home from work that when I came up to a stop sign it would die.. Not every time tho... It died twice on my way home. Should I let it sit until I get this fixed ot can I still drive it to work.

Damn, those numbers are all over the place. How did you not notice anything and allow it to get to this point? I suspect those numbers didn't just happen over night. I suggest performing a leakdown test before you pull the head so you can pin point the problems. 10 psi almost always mean bent valves, did you perform the wet test on the rest of the cylinders? I suspect that the motor probably needs a complete rebuild anyway so if you absolutely need to limp it to work, it probably won't hurt anything except the possibility of bad rings causing oil thinning damaging your turbo. Good luck.

Well my car seemed to be running fine over the weekend it was running really strong and then out of the blue my car backfires really loud.... And that's when the problems started.

were you at WOT when it started back firing...or was it just like out of the blue that it started...?

I was at wot when it backfired... This is the first time that this car has ever backfired. (I'm just gonna let my car sit till I fix this problem.) I hope I don't need to do a full rebuild but if I do I'm gonna have one hell of a street car when I'm done)

no you probably need a rebiuld with those nue comprssion test....10 is extreammly low... and in my opinion...its either a bad ring or even posibly a hole in the piston....i wouldnt go that far yet...but a similer thing happened to my old car...i was racing a car doin like 145 at WOT...the car backfired, sprayed oil and smoke and died...the car started up but was running on 3 cylinders...did a compression check and got numbers like yours....took the head off and there was a hole melted in cylender 1... i dont know if this is your problem but it definetly could be.....

 

[Amazin' Wasian]

Well when I get enough free time ill pull the head and let you guys know what happened.... Maybe a week or 2..

You smoked a piston,either a hole in the top of it if you did it good or broken ringlands if you did it a little.Smokes like a choo choo does'nt it.Nothing to worry about my son does this all the time.If you did'nt run it to long,you can just hone it and replace rings and pistons.

 

[Amazin' Wasian]

well i finnally got around to pulling my head off....turns out to be a melted piston.....
if you guys wanna check it out im documenting the whole rebuild here>>>
