????????????? STS Oil Return Question ?????????????? I am having a major problem with my STS kit....
I got the turbo mounted on my exhaust and hooked up the oil pressure line to
the engine(above the oil filter). and i hooked my return line to the sts oil pump and then to the oil fill cap... I started it up and it was fine for 30
seconds or so and then it just started spraying oil all over my underbody!!!
Yes the oil pump is working...(well. i can hear it, at least)
Also... what does the thing(sensor) next to the oil pump do?

Oh yea i forgot I pulled the oil fill cap (return line) and it still looked brand new... no oil....
as a reminder i only ran it like 20 seconds... then i started it again for maybe 10 seconds

Take the return line off at the pump and turn it on. You need to make sure the pump is returning the oil (which it sounds like it is not) Also, check the drain from the turbo to pump and make sure it is not clogged.
Your issue is a drain issue, so start there and figure it out.

Did you hook up the wires on the pump right? Or as in STS's case, wrong? On the STS kits I've installed (like 5 of them in the past couple years), the wires hook up backwards ... don't know if they changed it since, but I know for a fact that the yellow (+) wire goes on the (-) terminal and vice-versa. Swap them and see how it works, it's a simple thing to do and if it don't work, you can PM me and yell at me for wasting 5 mins of your time ... lol
The hob switch is to sense that there's no oil being pumped through to the front ... as in if it sees more than a set pressure, it thinks there's a blockage in the line <--- or something to that effect

well here is a little list off the top of my mind:
check the pump, as has been said... make sure it is pumping oil back to the engine.
make sure the one way check valve going into the turbo is working ok
pcv system?? what are you running?

what one way check valve?
I havent done anything with the PCV system yet... I did think it mattered.
****!!!
BTW RooRnZ28 I love your build...
and schantin... but hes not in here yet.

the check valve he's talking about is the brass cylinder on the oil line right at the turbo. It usually comes put together from STS and the fact that you're dumping oil down every outlet of the turbo means it's installed right LOL. I'm sure you've also hooked up the in and out tubing right....right?

Sounds like the pump is hooked up backwards if it's spraying from the turbine at both ends and you can hear the pump running.
The check valve that was refereed to is a brass 1-way valve that is installed prior to the turbine inlet from the oil feed line. This is to prevent pooling of oil from the inlet when the car is not running. Without a one-way check valve oil will pool into the turbine when the car is not running. When the car is started, the excess oil in the turbo has to go somewhere, so it seeps past the rings and into the hot and cold side pipes.
My suggestion is to check the wires again and ensure they are hooked up properly (yellow is NEGATIVE). You also want to check the STS warning buzzer. If the pump is running backwards, the buzzer should have sounded. The "thing" at the bottom of the oil pump is actually a flow meter that is directly connected to the warning buzzer. If the flow rate is below the threshold value, the buzzer activates. If all that appears well, check the oil return hose from the turbine to the STS pump and ensure there are no kinks or restrictions.
If you discover that the pump is NOT operating, then there is an entirly different list of things to check.......
BTW, you will need to clean the oil residue from the cold-side piping. If you do not, it will coat the MAF in oil mist and eventually make it into the intake. In a MAF tuned car oil will result in very poor performance by skewing the readings from the MAF resistors. Oil in the intake just makes a mess. Doesn't need to be surgical spotless, just wipe the inside of the piping clean with a cotton rag. For the long pipe under the driver door use a coathanger or similiar with a loop at the end to thread a rag through. Run the coathanger/rag combo through the pipe like a big a$$ed bore brush to get the oil out. This will save you from having to remove the entire pipe section, which can be a PITA.
Good luck.

Pull the rubber cap off the pump and crimp the connectors a little bit so they make better contact. Trust me on this we had the same problem on the last one we did and it made a fking mess.. You may think the pump is working but you are probably just hearing the fuel pump. If the sts pump is working you WILL DEFINITELY HEAR IT. IT IS LOUD AS HELL.
