Hey guys! been running a T3 T04E 60trim setup on my 1.8t, using the supplied pin hole size restrictor that came with the turbo. Long story short im getting oil blown by the seals for sure. Running -4an oil feed to said restrictor, which is literally size of a needle no bigger. And a 10an drain,so its big enough lol. Now this is obviously a journal bearing turbo i hear people say all the time that restrictors are for ball bearing turbos. Or engines that produce hi oil press. need them as well which is kind of a dumb question but which is true?

Just trying to stop blowing smoke on wot apps, and take offs or anything else having to do with smoking while driving the car lol.

Our vehicles have higher oil pressure then most other vehicles. So even with the oil restrictor, the oil pressure still forces the oil through the orifice pretty extreme. Like...80+psi at WOT extreme. Depending on what brand turbo, some handle it better than others.

For example, I had to step down to a -3an oil feed line to reduce pressure. Along with that, run two different restrictors on my ball bearing Comp Turbo. What brand turbo you have?

Wow thats extreme haha, but i have a 60 cold and .63 ar hot Cxracing t3 t04e, and beleive me i know china crap but ye. I installed a .065 and the smoking an oil consumption went down but i still get a nice cloud taking off and an even bigger one after i just got done doing a wot pull. Whats next lol. What do people run for a restrictorless line? just -4an fitting?

bump? would crankcase being vented to atmosphere and not having vaccum cause this?

Weird. I run a straight -4an with no restrictor on my Holset and it works great, no smoking. Sure the turbo is ok?

If you have poor blowby, as in excessive, that could cause high crank pressures with no vacuum on the crank case which in turn effects how oil will drain from the turbo.

UPDATE: pcv defiantly helped. didn't see much smoke at all. so confident that i cranked her up to 15psi now im getting a little more back lol. Im starting to think i need to step down to a 3an line should i still run the .030 restrictor that came with the turbo? how big of a difference is a 4an to 3an?

do you remember exactly what restrictor sizes you had to drop down to? perhaps i can try same setup lol thanks seerlah!

-4an is 1/4" hose and -3an is 3/16" hose, so only 1/16" of a difference between.

Bump? I ordered 3 an line and will running a .030 restrictor from the oil housing and a .030 at the inlet of the turbo be too much restriction?

Can't really comment on what the appropriate size for oil feed is or what the appropriate restriction is. Reaching out to the manufacturer of your turbo is probably the best bet.
