Oil in DOWN PIPE

[waldo320]

Hi all just quick question doing a custom turbo build on my 94 NA. So I get everything put togeher from a 91 legacy with a stock vf11 turbo get my car started up and holy crap oil is blowing every witch way so I take the turbo off and see that all the bushing are shot. So I buy a tdo4 from a 04 forester with 4000 mi on it get everything hooked up and there is small drip of oil comming from my down pipe still. Let me explain my oil system to you I am using a oil cooler sending and recieving unit that goes in the middle of my oil filter and the block so insted of going to an oil cooler I am using it for my oil feed and return. So why is oil still leaking from my down pipe?? Could it be just a normal amount of oil since I am not running a catch can, or am I double feeding the turbo with oil, and if so I have tried to get my oil pan off without moving the engine imposible! so has anyone tried returning the oil to the head , the only problem with this is let me know if I am wrong that during the vacum no problem the oil would be sucked in, however during boost I do not have gravity on my side to pull the oil back into the engine any imput would be most helpful!!
Thanks

Not sure about the leak, but if your cooler hookup is thermostatically controlled, it will only open up when it gets hot enough. So until then, no oil circulation out of adapter. Or when it cools down either. Does not sound like a smart set up.

well changed the oil return problem today just ran it to the vacum line on the top of the head started the car up again there is still oil leaking from the down pipe, and every time I start my car right it will idle fine until about 30 sec and then it just dies? this project is becomeing a major pain in the butt any help what so ever would be most appreicated!!!

I'll try to post again with more info when I have a minute, but I have to say:

You're breaking all the rules about turbo oil drain lines! You could be hurting your engine. Get a copy of Turbochargers by Hugh McInness or Maximum Boost by Corky Bell and give the relevant sections a quick read.
