There should be pretty much 0 oil pressure in the pan itself, as engines are designed to allow those vapors to escape (PCV system).

One bone-head move I made once was that I had an oil return from my turbo bolted to the pan, nothing unusual there. But I used a bolt with a split washer on it to bolt it to the pan. The oil leaked through the split in the washer. Put a proper bolt/washer on and viola, problem solved.

Just for kicks, take a look at your coolant too.

Take a rag and clean the pan from below. I'm sure you'll find where the leak is dripping from. Take pics .

What side of the block is it on? You make your own oil pan gasket out of rtv fyi. And have fun pulling your motor. A case of beer and an afternoon, you could pull the motor and put it back in.

Wait, if it's where your oil pan is and you aren't blind, then maybe it's behind your timing belt covers dripping from your cams.

Just park the car for a day and look above where the drip is coming from. Wherever the leak is isn't too far away from that drip:-/

ok...im scratching my head on this one..took off the valve cover, re-siliconed the tower parts like they did from the factory..looked like it was leaking by the cam sensor side of the valve cover..went for a test drive and its still leaking..i drove it hard and it jus blew oil almost in the wheel well on the springs. i have checked the return oil line, oil filter to see if it is tight, but when i let it run and get under the car it seems to be coming drippping slow from the oilpan area..

did the mechanic use the nipple on the pass side of the block for the oil to the turbo? maybe he messed up somewhere along there and its dripping down looking like its coming from the pan? thats what i can think of along the pass side of the block.....maybe a bad gasket on the oil filter when you changed the oil-uncommon but possible...?? little confused which side its coming from you said you checked the return line and the oil filter. they are on different sides. which wheel did it spray on? and any oil leak that is spraying sounds like a pretty serious problem....

There is NO OIL PRESSURE IN THE PAN.... NONE!! PERIOD!

The oil pan is the RESERVOIR for the pump...The oil pump sucks the oil out of the pan and squirts it on various engine components ( cam, pistons, etc.) Then it trickles back down to the pan to get sucked back up again.

Plus, as far as I can tell, there is no OIL PAN GASKET, just sealant (correct me if I'm wrong).... If you tackle the oil pan, use "ULTRA GREY" It is the best.
