STS oil problem So we have my system all done and we decided to put a new oil pump in it. so we put in the ls6 oil pump. now when I get on it I make crazy oil pressure! like I should be at 40 but it will increase all the way up to 60 70 PSI!!! and when we had her on the dyno the oil reture line started to over flow onto the engine! what do I need to do here?
figure out where its coming from; the cap where the hole is or the coupler.
If its the cap where the fitting is screwed in, you may try a little thread tape to seal it better. If its the coupler, you may need another one.
I really wouldnt think the engine oil pump would have anything to do with it. It supplies pressure to the turbo, but your scavenging pump supplies the return pressure.

my friends car is 40-42 idle.. then when he gets on it, it goes to 60-65.. i was told this was normal do to a turbo..
he also has a 05 WRX STi.. and its at 65psi most of the time.. its a turbo car also

If you're leaking from the return line of the turbo, it has nothing to do with the LS6 oil pump. See where it's leaking from and tighten the fitting, use some teflon tape there, or replace the leaking component.

The STS return system into the valve cover is not a very good design, in my opinion. It is way too easy for it to leak oil onto the exhaust. We're having a problem with it, and I have read of others who are also experiencing problems. It is totally unrelated to your engines oil pump, as has already been mentioned. Bob

I am removing the PCV system on mine, and I'm going to use one of the nipples off the valve cover to run my return line (one that is used by the PCV. And then I'll stick a breather on the oil fill hole, as noted above. I don't see any reason why that shouldn't work.
