AGP Turbo oil scavenge pump question. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I see people say the oil would get into the exhaust if there were problems with oil scavenging.

Could oil get into intake instead if the pump was failing or there were some problems with the drain lines?

Not that I can think of. Most likely is blow-by. Do you have catch can or some sort of crankcase ventilation setup?

I had PCV system mounted incorrectly so that there was pressure in the crankcase under boost.

A lot of oil was coming out of the blow-off valve.

Now it vents into atmosphere via AGP catch can.

And I want to find out if the the only reason for oil under car was blowby or any other install related things could add to this.

absolutely. you will see oil in the cold side even when the scavenge pump is working correctly.

It might take a while to clean all that mess out from when it was hooked up wrong. Clean out as much as you can.

BUT to answer your original question- Yes, oil can leak into the compressor side of a turbo if the turbo is filling up with oil and pressurizing, it will squeeze out both sides. And once solved, that will also take a while to clean it all out.
