single turbo 93 oil issues
 

Having an issue with the car blowing oil out the turbo under full boost above 5600 rpm, cruising it's fine and boost on the dyno was only at 8-9psi (also wouldn't hold boost, but that's another part).
every attempted pull the car would smoke out the shop quite bad, drove it 100 miles home, wot'd on it a few times and it hasn't smoked again.
it's a 93 aggressive street ported motor, 550/1600 walbro 255, fmic, gt3582r modified rx7 store mani (I think) 3" v-band outlet to d.p. to 3.5" greddy cat back. Apex power FC w/dataloggit.
Turbo is 2 weeks old, never seen full throttle until yesterday, wasn't smoking again last night.

What size oil feed line, and restrictor? What size return line? How is your crankcase vented?

I bet he capped off the oil filler crankcase ventilation

ok found some issues, the check valve from the oil fill cap to the mani was clogged, and the 2nd port was capped off by the previous owner for some reason. Redoing the PCV system and new catch can tonight. Also one of the t-bolts on the FMIC had broken on the dyno I guess, probably why it wouldn't hold boost for shit.
oil feed is a -4an line adapted off the stock feed, I did run the restrictor in the feed, return is a -10an (2 45deg's so it's pretty much straight down). to the front return flange.
Pretty sure it's just a PCV issue, will know more tomorrow night when I put it back together.

well redid some things this weekend, will post up the pics tonight. Added a new 3/8 vent line and catchcan. Cleaned the old check valve out and it now actually works. Fixed the boost leak. now the car is lean as hell so I can't really drive it until I bring back down to finish tuning it.
unless someone has a decent fuel map I can use until then (street ported, gt3582r 550/1600's)

you dont need the PCV valve to the intake, just vent the crankcase.

well I did both. can't hurt hopefully.

trying to get in touch with the shop to get my car back in to finish tuning it. Can't tell if it's fixed until then.

well richened it up a little last night and took it for a few 7500 rpm blasts around the neighborhood. no more smoking yay.

Post Pics man!! I think my pcv valve is clogged as well...

I dunno how well you can see what we did, but it works
