Ok, so whose right about this? If you have oil hitting oil, then that means your line runs right into the oil, which is going to cause it to back up in the turbocharger. I now know this from experience unfortunately.

But now you're saying oil into air causes foaming? Uh...

Thanks for the pics btw.

huh? you need to go pour soapy water into a pitcher and see what happens, then pour the same water through a hose into the same pitcher..

how would oil back up into the turbo because it terminates under the oil line? that doesn't even make sense..

basic hydraulics will tell you to NEVER terminate any return line above the oil line. its not the oil hitting the air that causes foaming, it's the oil hitting the top of the oil. just like filling a bucket up that has soap in it. if you hold the hose above the water, the turbulence of the water landing on the top of the water will cause the soap to foam. if you put the hose under the water it does not disturb the oil..
