i need to replace my valve seals, has anyone done this firsthand?? Options

[forkee]

k so i thought it was my turbo's fault the first time i was burning oil cuz when i took it off and ran stock, i didnt get any smoke. after getting the turbo rebuilt, it fixed the oil leak problem, but it was smoking again. turns out the added pressure is letting oil get past the seals onto the stems and burning out the back. and its really bad too. i added some "no smoke + stop leak" stuff, and it helps on the low end, but when i really punch it, i still get A LOT of smoke. i mean it clears the freeway about 50 feet behind me.

so my question is, has anyone replaced theirs or gotten it replaced?? i need to get this done asap because its really starting to bug me. plus its deterring me from boosting because i can never go full throttle. if anyone has had this done, how much did it cost for either DIY or for a mechanic to do it, what parts will i need, and where can i find those parts.

thank you

Well most kits out there are -4 feed line and -10 return line. Some suggest going as small as -3 and -12. So if you custom made your kit and fitted your own hoses, I'd definitly check those sizes.

Going from PCV to turbo intake will provide a decent vacuum, obviously it will be strongest vac when you are boosting, but won't present a problem otherwise. If you wanted to ensure max vac when not boosting, I guess you could also split the PCV line into both the intake (where it is now) and the turbo intake, but not sure if thats necessary.

If you wanted to just run the PCV to turbo intake, then yes...cap off the intake mani nipple.

Again, your PCV system and blow-by should not create a 50 foot clearance of smoke. What will cause that is a bad turbo. If you rebuilt your turbo a while ago, and this smoking problem has slowly started up again, then excessive pressure from the PCV system could have already deteriorated the seals. But its not something that'll happen overnight.

So I'd check your oil lines.
