Turbo leaking oil, T-25 Help!!!
i just install my turbo on a D16Z6 vtec sohc today. the ****** is leaking oil big time through the down pipe and the compressor side. the play shaft is pretty tight. the turbo seems to be in an excellent condition. after the leaking, i also try a brand new one, which is suppose to go in my brosther's car. it also leak but only on the downpipe side. the only problem i can think of right now is prabably the oil pressure is too high, i do not know exactly how much psi is going into the turbo. if someone know or experience this problem or have any suggestions please help. thanks.

Sounds like your oil return is backing up... Be sure where you tapped into the Oil pan has to be above the oil level, so basically at the top of the oil pan. And make sure there is no kinks in the line, and its a large diameter hose for smooth flow. Its very important.

Re:Turbo leaking oil, T-25 Help!!!
i did tap the oil return on the top as much as possible. the return oil line is a 1/4" line, like the one that is going into the feed line. do i need to make the return line bigger? the return line is pretty round and smooth. i custom it myself. maybe the return line isn't bigh enough like the original one. anymore advice would greatly appreciated. thanks.

Ahh, thats your problem, the oil return needs to be fairly large, I would go with 1/2 - 5/8 the bigger the better dude.. oil is just getting backed up in the center section and dumping out the seals.

Re:Turbo leaking oil, T-25 Help!!!
i have tried the return oil with a bigger pipe that goes into the top of oil pan(factory pipe from mitsubishi). i even let the return oil straight down to the groung into a bucket and the ****** is still leaking big time. what i notice at this time is the flow of the oil that's going out is not freely like the water side. i blow on it between the water and oil, the oil seems to be some restriction, is this normal? the oil going in is very fast, but the oil coming is very slow, or maybe the turbo deal is bad? is it safe at all just to run turbo on water cool? or do i need both oil and water.

Re:Turbo leaking oil, T-25 Help!!!
make sure you dont have your turbo setup wrong. there is a feed hole and a dump hole in the center cartridge it isnt like the water that flow either way. one way only. make sure it isnt backwards. sounds dumb but may be it.
