6k mis fire trouble????

[viper066384]

i have changed nothing on my car and was running great but slowly getting worse it is starting to misfir at 6k not detonation cause that wouldn't progressivly get worse but every time i take it out it gets worse so i have bad oil seals on my turbo im sure there gone i got oil every where in my charge pipes and when i try to rip on it smoke will come out, i run the plx so i know i also run about 12 to 1 boosting 15 psi and when i mis it gets richer so i figure it is the oil causing such a problem and getting worse. any thing?
