first run on the street today....having issues

allright, just to sum it up quickly, i have a mp t 70 set up with a ponydown stage 2 hotside, custom coldside,csx intercooler, .68 exhaust housing @ 10 psi, timing @ 22 total(for now) msd 50# injectors pmas blow thru setup, ok first issue is that im burning oil out the exhaust??, it doesn t do it at idle(neutral) reving it up to 6k, only under load, so this leads me to believe its a pcv problem, but ive never had a pcv problem before??? my oil return is huge so i know its not that, kinda at a loss, when i get on it, it will smoke like a chimney blue smoke, today was the first trial run, also its kinda turdy @ 6 degrees on the distributor , 22 total, any help will be appreciated, thanks mike

i also have a 7 quart pan and a high volumn oil pump which put out 70 psi of pressure when i get on it, my friend said i could be blowing oil right thru the turbo s seals from the oil feed, is this true, if so how do i correct with out tearing it down????

Are you running any kind of oil restrictor in the supply line to the turbo to reduce the oil pressure supplied to it?

you probably are going to have to run a restrictor. Your oil pump is putting way to much out I would think. What size feed line you have?

i checked my oil feed and i have a restrictor on there allready, just like the function 7, man i don t know what to do now, is there any tests i can perform to see if im getting to much oil to it? add a second inline restrictor, this turbo has only 2.5 miles on it, its from that turbo mike guy in flordia where everyone is getting these things from, my return is a -10 an, but i just ordered a -12an return to see if it helps, ill tell you guys my progress when i play with it this week/weekend

Are you sure it's coming out the exhaust? If your pcv is not plumbed (or your getting excess blow by) correctly it's possible you are blowing oil out of the dipstick tube or hole (or possibly valve covers) under boost and burning it off on the headers. When your moving it appears that it's coming out of your exhaust…when in fact it could just burning off the headers.

Make sure you are not pressurizing your crankcase in anyway. Don't hook up the pcv. Make sure you don't have the hose to the TB connected. Then see if it works better. Is your oil drain down hill the whole way?
I had the same stuff when I first built my setup.

yes down hill all the way on the return except a 3/8 npt pipe that comes straight out of the pand 4 inches then hokks upward to 6 0 clock on the turbo, ill get some pics, the hose is gone from the vc to tb, and i have a check valve in the pcv line i checked that and its not sucking oil, i may try pulling a vaccum from both valve cover s to the port on the front of the intake and put another check valve in as well
