So if I let the car idle for a while it starts burning oil and fouls my plugs. I dont think its the engine cuz I had this 4 port running in NA form for a 15k miles no problem.. Now I put my stage 3 BNR turbo on and wired up the wolf3d.

I've got the FD OPR, so I was thinking maybe its the turbo getting too much OP, but then why are my plugs getting fouled? When im driving the exhuast is fine. During idle im seeing about 11.5/1 AFR.

Anyone?

 

Pull the turbo inlet duct off and look for puddling oil/ severe wetting with oil of the turbo inlet duct. If it's wet, then suspect the turbo.

What kind of blow off valve are you using? Not stock, or stock?

 

Well I had the air filter off for a couple days when I got the car running and it was doing the same thing. I didnt see any oil in there at all. I am using a turboxs RFL BOV.

 

Are you running an aftermarket oil pressure gauge?

No I've got the stock one, but I also have webber jets in the E-shaft so that lowers my idle OP down a bit. I dont think its over stock OP with that setup during idle.

Bryan at BNR supercars said its becaue the turbo isnt draining the oil good enough. As a solution he said to run a vacuum line from the TID to the 2 oil nipples (oil filler neck, and housing) to create a crankcase ventilation. I will be doing this tomorrow.

edit: I also run premix with OMP blocked off. 1ounce per gallon of gas.

 

Try this to see if it fixes your problem temporarily...
Uncap the oil filler cap and see if the problem still persists.
If the problem clears up, you have a pressurized "crankcase" problem as BNR had mentioned.
Don't be trying to corner hard while you have the oil filler cap removed - you'll just make a big mess in the engine bay!

Well right now those 2 oil nipples arent connected to anything, they are just open.

 

I just did the 5k rpm test where you hold it there for a minute then let off. Not a puff of smoke at all.. When I start it on a cold engine I dont think there is anything either, just if I let it sit there idling and it gets warmed up. No smoke during driving ever... if I idle the car and it starts smoking and I take it for a drive, all the smoke goes away.

 

It might be the turbo is bad.
Check intercooler and hoses for signs of oil.
It should not be wet inside.

Well I just pulled the Intercooler and there is no oil in there, so turbo isnt pushing oil into the engine... Then I pulled the spark plugs and they were dry so I guess its not getting into the engine. So that means my plugs get fouled from a tunning problem. I still have to figure out what that miss is from.

I think some oil might be getting through becuase when I first installed the ECU it wasnt tuned at all and I flooded it out like 4x, so there is a bunch of gas in the oil. Im doing an oil change right now actually. Then Bryan at BNR said to weld shut the oil pressure line to the turbo, then drill a small .075" hole in there to restrict the oil. My dad is actually at work with my oil line right now so he can weld it for me.

 

I replied at NP, but incase you see it here 1st-

It was all out the exhaust side when the oil couldn't drain fast enough. Race oil pressure regulator. I restricted the turbo oil feed 1st and it did help, but still a little smoke until I put sump under vacuum.

 

Check the simple things first...inspect the OMP and it's linkage to see if it's hung up. I've seen more than a few TII's with weak throttle body springs making for a sticky throttle.
