So, my car is burning smoke. Lots of it. Blue smoke. Like really bad. Smoke comes out the exhaust, and some of it comes from the Turbo area. Engine was rebuilt about 60k miles ago. I don't drive her hard. So I think oil control rings are good still. I originally thought it was the turbo, because I found trace amounts of oil in the intercooler. But not that much. So I got a JDM low milage turbo. Put her on thinking the problem was resolved. Bam. Same problem, just as worse. The turbo looked in good shape, how did I end up with another bad turbo!? However, I was doing some research and realized I capped the crankcase ventilation nipples on both the center iron and the oil filler neck. If I pull the nipple off the neck, will the smoking stop? Additionally, would this small issue cause the massive amounts of smoke? I don't see how the crankcase would cause so much oil to enter the housings somehow. Some expert feedbad would be appreciated. Thanks

Oh also, pulled my spark plugs. Spark plugs are covered in oil.

 

Ok..capping off the crankcase ventilation will cause a Build up in pressure on the Oil system and it will in turn allow oil to bypass the oil control rings on the Rotor,,and Voila!..Smoke.
I would try T'ing the two oil lines(the crankcase hose and the center iron hose) together and then Either venting it to atmosphere,or put a small catch can or the like at the end of the hose.
Another thing that you could do with the lines is to Lead them up to the Throttle body and attach the hose.but make sure that you have a check valve so when you BOOST it doesn't put Positive pressure back into the Hose and into the Oil system again..

 

As soon as I got home I took the cap off the oil filler neck to see if just leaving that open would make any difference. The car started up, and started smoking a lot once it got warm again. I left it on for maybe a good 10 minutes and it just continued to smoke pretty good. I'll mess with it more tomorrow when there is more day light, and when I'm not tired from work.

 

I've confirmed that the problem is stem from my Turbo(s). I'm going to purchase a rebuild kit. But I'm not sure which Seal to get. Can anyone confirm which seal is for the S5 Turbo? Thanks.
