Might be a little off topic but talking about BB turbos and restrictors. I have a friend with a big turbo (EFR) focus ST. Smoked out the exhaust not to long after install and would leak oil. Went in circles for a year with bad information trying to fix it. He too was told not to run a restrictor as EFR states they have one built it. But one day he had a conversation with a shop that frequently installs EFR's and the shop owner said he sees this issue a lot and runs restrictors on EFR's. So my buddy took the advice, put one on, never smoked or leaked since. Has been running the restrictor for 30k+ miles with no issues from turbo. Also, turbo smart has released a product that supply's exactly 40psi of oil pressure to BB turbos. Believe this is it: http://www.turbosmartdirect.com/Pro...ure-Regulator-OPR-T40/OPR-T40-40psi-Blue.html

This is my problem.... The car idols and runs perfectly fine when I step on the gas and the RPMs reaches about 5K the blowoff valve releases and blows oil all over the engine bay I have brand new return lines and rebuilt turbo’s. I checked the turbos and nothing is wrong with them no play no oil leaking from them.

Just trying to sort this all out. Car has been down due to laziness since last July. Got it back on the road today, and when I got back from ~15 min of driving, the BOV had "shot" oil all over the place.

Car has a Motiv700 kit, BMS OCC plumbed to filter inlet like the old fftec bottom mount kits, HPF IC, tial BOV from my old CP-e charge pipe, Motiv PI that is installed but not connected electrically, and other miscellaneous stuff.

OCC is dry, OCC lines are dry, CP had standing oil in it(pic below). The only thing I can think is that the turbo is blown and pushing oil passed the seals into the intake stream. The only other way I would see oil getting into the intake path is through the OCC, but its dry.

Thoughts? The turbo has maybe 1k miles on it...

Does anyone on here have any experience running the Turbosmart OPR-T40 oil pressure regulator?
