Would a oil dumping turbo cause this?

[Norcalrallyist]

My turbo had been burning oil almost since ive put it on. Ive also done nearly everything to try to fix my knock problem. Is there any way my oily turbo could be causing my knock problem? I didnt think it burned oil constantly because it doesnt smoke all the time but when i took the engine out for a swap i notice oil from the outlet side of the turbo all the way to the intake.... Could this oil be reducing the efficiency of the intercooler enough to cause knock at boost?

It shouldn't, the only way it might cause some knock is if the spark plugs are all oily and fouled causing them to not spark right, and causing it to miss.

what octane fuel are u using?

are u knocking all the time? or at boost? what boost level are u running?

have u tried MCCC on your engine?

is your ignition system up to snuff?

hows your fuel pressure?

hows your base ignition timing?

u can try cleaning out your intercooler with kerosene.. i did it, works great.. clean as a whistle

bone stock except for a 2.5" exhaust. All tuning has been checked and rechecked. Ignition is new plugs new wires new fuel filter and air filter new. I dont have a fuel pressure gauge so i assume its correct. Ive bench cleaned the fuel injectors ran chem tool threw the tank and octane boost. I havent used mccc yet. Ive tried cooler plugs. Ive checked ecu for leaky caps. Ive replaced the knock sensor. This happens at boost starting at around 3.5-4k
