Oil leaks are driving my crazy

[cheeseraid]

Alright, my Benz wants a new part but I can't figure out what it wants. It's a 190e 2.6 auto sportline (and if it keeps this **** up it's going to be a 190e 3.2 m104 lol). I keep having oil leaks outta the valve cover gasket, oil pan, and rear main seal. I fixed the valve cover and oil pan a few times now but they keep leaking like the car has high oil pressure. I cleaned the breather out on the valve cover and checked the oil passages on the top. Still didn't fix the problem. My dad thinks it's the oil pressure relief valve, he has a 66 bug that has the same kinda system. Go figure, Germans never change things lol. From what I can find though is that valve only works at full oil pressure. I don't have a spare gauge to measure if it's going over 3. When the motor is idling it hovers around 1.8 - 2.2 bars never lower. I remember about a year ago it was around 1 - 1.2 so something is off. As soon as the motor hits 900 rpm it pegs 3 bars. I'm running 0 - 40 Mobil Euro Synthetic in it like always so that can't be it. I have a slight amount of lifter knock but that's normal for my oil. I also noticed since this has started it won't idle smooth. The motor is dialed in right. 52 degrees on the dwell at idle 42 degrees at 2500. The plugs are burning smooth and the caps and wires are good. Cylinder pressure is all above 180 on each cylinder. Anybody got some ideas? I took it to my local indy and he said to run less oil in it. WTF, I can't keep the whole 6 quarts in it lol. It leaks out about a quart in a month, dosen't burn it, just leaks it. Thanks guys.
