I have been running my STS for about two years and I really don't like the oil return. Anyone do anything other than drill the pan?

I took mine from that stupid looking replacement cap they give you and plumbed it into the driver side valve cover in the back. Now it isn't really noticeable unless your looking for it, and I haven't had any problems with it so far.

Anyone make a seperate reservoir of oil for the STS? Use gravity to feed the oil and the pump to return it?

tapped it into the valve cover buy drilling and tapping and just used the fitting out of the cap they give you

Has any one tried this for an STS? Where are you guys putting the fitting? The rear of the cover? Any photos?

Anyone put one of these on a car with stock manifolds and cats?

You can't use one of those because the oil coming out of the turbo must gravity drain (no pressure). If it is pressurized like that would do, trying to push it back to the motor, it will push oil past the seals in the turbo and smoke REALLY bad.

Only one port is pressurized, the other is a return, it is for a oil cooler loop.

With a oil cooler, there is positive oil pressure all the time on both the feed and return. The return dosent just dump in to the oil pan, it feeds the rest of the oil system. There was a guy on the sssilverado board that tried one of those sandwich things that goes in between the oil filter and the pan to feed his remote turbo and it pushed oil past the seals like a ****. This would do the same thing. You can try it, but I got a $100 that says it won't work.

The back pressure of the oil going back through the motor should be take up by the sts oil pump. I am only diverting a small diameter fitting from the area.

Can I have my $100 now?


Just a joke, I think I am going to tap the pan, thanks for your help.
