LOL, at the know it all stuff. I learn new stuff every day Tengis and am happy to do so. Constantly am saying "I don't know everything" and admit to having been wrong many times in life. Personally I hope to continue that for many more years, it's called humble. Hop back off your inflatable horse, because she's got a leak that you need to patch.
The quote you grabbed says flow, not pressure. I'm very new to turbos and clearly you have more experience in this arena. On the four bolts, it should be clear to someone with your background that the pressure relief "valve" is accessed by pulling the filter adapter and not the pump.
How's about you guys take some Pamprin to help with those cramps and give the OP good information with facts to explain why I'm wrong and how best to build up his ride.
Found this info on Turbo 101 by Googling. http://www.turbobygarrett.com/turbob...o_tech101.html
Doesn't go into a lot of detail about oil, but does have some and it doesn't appear that it's as worried about the pressure as it is the amount of volume.
