I'm looking for some advice on what might be causing my turbo to be spitting oil, and it looks like quite a lot.
I am still in gocart mode and do not have an exhaust behind the turbo, so thats why I say the turbo is spitting oil.
I'm using an 03 WRX drivetrain. My only driving has been gocarting around my neighborhood, so not a lot of driving and not any really hard driving.
I recently installed a couple of catch cans following the raduim instructions. I did not seem to have oil coming out of the turbo before I installed the catch cans, but didn't want to rip them out before getting some input as to whether this is the likely cause of my problem, or something else more serious.
One catch can is inserted b/w the PVC and crankcase, and the other b/w the head breathers and turbo inlet.
There is no oil in the catch cans as far as I can tell.
The one difference that I have with the 03 WRX and the radium instructions seems to be the location of the PVC valve. My PVC valve is in the intake manifold. The Radum instructions indicate that the PVC valve is in the 3 way connector in the top of the crankcase, so my hoses do not exactly follow the instructions. So, where the instructions say to route a hose from the intake manifold to the catch can, and then the other hose from the catch can to the PVC valve in the 3 way connector - my hose goes from the PVC valve coming out of the manifold to the catch can, and the other hose goes from the catch can to the 3 way connector in the crank case. I think the Radium instructions have the catch can on one side of the PVC valve, and I have it on the other. Even if I have this wrong, I wouldn't think there would be that much oil going through those breather hoses.
Is it possible to suck oil into the exhaust/turbo through this catch can tubing? The output of the turbo is covered in oil and I can see it spitting after less than half mile of driving and probably not going over 3000 RPM.
The other thing of interest is that I have a 2 quart accusump that has been left open, so there have been a couple of extra quarts of oil sitting in the oil pan. Could this extra oil get into something that would travel to the exhaust? After startup the accusump is pressurized and that extra oil would go into the accusump.
Or, do I have some other problem that I need to look into? I've only go carted around the neighborhood 6 or 7 times before, but never saw oil spitting out of the turbo before.
Thanks for your help.
