Finally got around to putting the plates on the car today so i could take it for a test drive. Car runs great but even after the rebuild and installing an oil resticter the SOB still smokes under boost.
At this point I am about ready to sell the damn thing as I cannot afford to throw any more money into it. Really can't understand why the thing did not smoke at all when I first installed the turbo since now it smokes even with the restrictor installed.
I really can't see me driving this thing on a regular basis if it is going to spew oil smoke out of the exhaust ever time I get on boost. b

You are sure it is not smoking from running rich this time? I can't believe the bad luck you are having. I hope you figure this out soon.

TRP951

what kind of chips are you running? Also are you running a catch can? Is it routed back into the j boot or maf pipe? Make sure the AOS is routed to the j boot or maf pipe before the turbo to keep vacuum on the crankcase or your turbo wont drain right and the oil has to go somewhere

david fracolli

I am running Guru chips with a mafterburner to fine control the fuel. According to the wideband I am not running rich under boost. All runs were done under partial throttle.
Not running a catch can at this time. I have one but did not install it as last time it made no difference. Guess I can install tomorrow and see if it makes any difference. AOS is routed to the stock posistion on the J boot at the moment as I have yet to install the MAF.

im not knowledgable with restrictors, but i heard of people having to get smaller ones after putting a smaller one in already.

david fracolli

I am a little concerned about going any smaller. I find it hard to believe that even under 60+ psi of oil pressure that a .080 hole can flow enough oil to flood the turbo instantly under partial boost.

you might want to check with SFR about the oil restrictor or i think david floyd had the same problem with his turbo a long time ago

David Floyd

Turbo was not the smoking problem on my car with new rebuild.

david fracolli

I spoke with Tim before I did the install and he is the one that suggested the restrictor.

david fracolli

Checked the car out againj this morning and it took me all of about 2 minutes to figure out what the problem was. All I am going to say is that it was my own stupidity! Turbo now works great. I am able to hit 17+ psi in 3rd gear at part throttle. Have not tried any full throttle runs yet as I am still trying to fine tune the part throttle maps along with burning off all the old oil that is still in the exhaust.

SamGrant951

he recommends a .080?

EdC

Sooo, fess up! What was it?

david fracolli

In my haste to get the thing back together I had swapped the AOS line with the ISV line.

David Floyd

I did that once many moons ago, blew my cam housing gasket out

david fracolli

I knew it had to be something stupid when the damn thing started smoking as soon as boost started building.
