Turbo Oiling Problem!!!!!
Turbo Oiling Problem!!!!! ok so i almost finished my custom rear mount setup...i connected everything except the charge pipies... i drilled next to my oil filterfor the feed line which is goin to the turbo (AN -6 i believe)....and i have the return line(AN -4 i believe) coming OUT of the turbo, UP over the Axle THROUGH a MOCAL Oil Pump which i mounted in the tunnel area(pretty high up actually)...and then routed along the chassis to the front of the oil pan..everything has nice russell fittings and braided lines...
SOOOOOOO First startup to check on leaks and the pump etc etc... and the TURBO isnt even moving at idle??!?!?!?!?!?...exhaust side is open to atmosphere as well as the charge side to see whats goin on, so i spin the wheel with my fingers to "jump start it" while the motor's at idle and it goes but verrry slowly...i rev it-it spools fairly quickly..and throws out muddy/oil/water crap...??? i guess humidity+carbon+oil=crap from inside the exhaust pipes
Anyways i keep lookin at the blades/shaft and notice a good amount of oil goin everywhere....im thinkin the MOCAL pump im using is not gravity fed so i disconnected the return line from turbo to oil pump and almost sucked in my dam finger lol IT CAN PUMP an elaphant THROUGH THAT LINE i guess the position of the line is making it back up or pool up and causing it to leak through the seals and out of the blades ....Its kind of obvious but my question is does my return line being over the axle and pointed up traveling UPWARD to the pump the reason why oil is coming out of all the seals on the turbo?? and not flowing well back to the pan????
THIS IS THE PUMP IM USING------

MY OTHER QUESTION is could this be TOO MUCH pump for this application ORRR should i just stop being a dumbass and position the dam thing as level as possible to get the best flow from the setup??? without any leaking or spewing or oil everywhere?? THANKSSSSSSSSSSSSSSSS in advance

Be positive the pump is "pulling from" the turbo... also, me feed line (to turbos) was like -4 and my returns werew like -8. Lastly, just another note... and vertical rises in the oil line in the return side should be just that...vertical... do not allow for long gradual rises in the line.
Keep playing, youll get it figured out.

my dawg albert wassup man its alex balck ss conv hows the project doing
yeah ive always seen the return line being much bigger then the feed line so maybe thats ur problem lets see wat others advice

Something sounds wierd here.
First of all the turbo should spin free with your fingers and remain spinning for a few seconds if you give it a good spin, it should also spin at idle.
Second your feed should be the -4 and your return the bigger, -6 8 or 10 and your CHRA should be clocked so the feed section is pointing straight up and the return section is pointing down.
With your scavange pump I wouldn't think a -10 line would be necessary.
When you say "rev it-it spools fairly quickly..and throws out muddy/oil/water crap..." where is this coming from? If oil is seaping into the exhaust or compressor housings you have issues.

That will do it, they can be turned up to 30deg but generally straight up and down is best, its also good to cycle your scavange pump after the car has been turned off just to suck anything out you can and keep oil from seaping past the seals.

i just think my biggest issue right now is how far up the pump is and how much the oil has to travel UP to the friggin pump.... so i guess im goin to have to re-mount the pump somewhere alot lower....
That is wrong, when the car is turned OFF after driving you need to wait a few seconds then cycle the oil pump that way while the car sits oil doesn't seap past the seals.
Also try to avoid parking your car on inclines where the noise is higher than the back of the car, if anything put the back of the car higher to avoid the same problems.

ok so imma go outside and re-mount the pump, cut and re-do the line, and run the line under the axle or wherever gravity ill help it move...pray for me 
ill post up in an hour or so...
ill post up in an hour or so... ok cool i fixed it...or so it seems...ill post if i have more problems...just took it for a few laps and came back, checked it, no leaks, drove again, checked it and no leaks or oil anywhere so i guess the relocation of everything was what i shoulda done in the first place... THANKS ALOT for the help

no billy, what i meant with the question was that at first i WASNT using the check valve and me and my friend were wondering why it would help sooooo much...so we jus hooked up all the lines without the check valve and looked at everything to see what was going on....(i start it up and the leaking problem starts)
i turn it off & THEN i relocated the pump and return line to a lower position so that it would be almost level if not lower than the turbo(declining)...that seemed to help alot but was still gettin oil in there when the car was shut off(here's where your check valve idea FINALLY made some sense to me and my friend)...then all i did was buy a few fittings to intercept the braided line and put the check valve a few inches from the turbo on the feed line....NO Leaking whatsoever so far.. im sure some oil gets in there but how much oil can there be in a few inches of line...
obviously me and my friend were eating crap and we were thinking that check valve wouldnt be that helpful but it definitely solved the "problem" i was having..thanks alot, ur the man billy woooooooo
