Spend the money, do it right the first time.
Or spend the money going cheap. Then spend extra money replacing parts that are now damaged. Then spend the money that you should have spent the first time doing it the correct way.
when it comes to parts such as intakes, exhausts, heat exchangers, and stuff like that. You can fab up stuff or have exhaust shops make you a part that's gonna be hard to beat and it cost next to nothing. But when it comes to internals, or something like supplying a turbo with the correct oil pressure and giving it a correct oil return to the engine, you probably should just do it right the first time.

a few of those pictures in them selves prove that its a flawed system.
see the oil puddling and dripping from the bottom of the exhasut housing on the 3rd pic?
on a journal barring turbo in witch you use full operating oil pressure(not all journal barring turbos are like this) i could see this possibly working as you'll have enough exiting oil pressure to over come the oil at the bottom of the pan, however on a DBB CHRA this would be epic and total fail. as those CHRA's tend to operate at oil pressures in the single digits.

what that pic proves is that i hade the vent line too low not enough drop in it and when the car was shut off the oil would drain out the line and out the seals cause it was backked up while not running. THAT WAS LIKE TWO DAYS AFTER I GOT IT RUNNING!
ever since i fixed that it has not dripped or smoked EVER AGAIN, i have 9300 mi on the car since then with not one issue...
dont hate on the system cause honestly if set-up properly (which is were most go wrong) it can and is working perfectly fine for me... and that is a FACT.

the "vent" line becomes the drain once the oil in the bottom of the lines equals out with the remaining oil in the pan once the engine is running.
there for, a serious amount of exiting oil pressure is needed.
if you want to try and argue physics behind fluid flow and pressure to try and protect this "system" then go for it. you'll be wrong.
if we take this, and try it on a real turbo, a DBB unit, it wont work.
i'm not "hateing" on the system, just pointing out where it works and why.

This system would almost work better if the drain plug had a pipe that stuck up into the oil pan above the oil level. It would self drain, I just don't know if it'd drain the incoming oil faster then it'd take it in.

You have an automatic right? I could be wrong, but I remember reading the drain boss on the block is not accessible because of the automatic tranny....

a segmented journal barring vs a dbb is easy, dbb wins every time in terms of response. all things being equal.
if you go to a full sleeve style then its closer, but still not equal, once again, in terms of responce. and with things being held equal.
however all the big boy's will be a full sleeve center section as they are able to sustain much higher thrust loads then dbb.

06black is right, this setup is nonsense. For all the extra work, money, effort you use in buying tees, fittings, tapping the waterpump cover or whatever the hell you were talking about on the 1st page and the extra line you can just drop the pan, tap/weld on a bung at the top of the pan and be WAY better off. it will look and function way better than the setup shown in the previous pics.

drop the pan. drill a hole. weld fitting above oil level. run new line. put it all back together. forget it. the drain plug drain idea is a failure waiting to happen.

That's the plan. I always thought draining into the oil was going to put a lot of back pressure into the lines, but I'm glad I've confirmed it. Thanks a lot guys, now to get this thing running.

well of coarse there is a better way (tapping) all i was saying is that this way will work fine for some applications, of coarse it wont work with dbb...
but anyways, the reason i choose this system is that i wanted a virgin oil pan in case the car ever went back to s/c or something... i live in ca. you never know what set-up i'll be running (smog)
