Okay I am having some trouble with my oil drain line. The turbo has been leaking and buring oil since I put it on. I have a feed restrictor but there still seemed to be too much oil in the turbo. I took the return line off and to my surprise oil drained out from the pan. The return bung is as high up in the pan as it can be just to the right of the coolant pipe. The engine only has the regular 4.5 qts of oil in it and I really dont know how I can move the line any higher. I realize the car is jacked up when I was doin this but its really not at that much of an angle and I lost a good quart and a half or so. Has anyone else had a similar problem or now what I could do to fix it?
the car is also off, during running the will be oil out of the pan.
make sure the line is big enough 3/8" or 1/2" and make sure it is not kinked

Okay, the line is 1/2" and I did an experiment with a clear plastic line, (IM NOT leaving it dont worrry) to see where the oil was going. No surprise that with it running the oil was still backing up in the line. I had an idea that maybe the oil in the pan might be pressurized if maybe my PCV system wasn't working so I took the breather filter off of it and hooked it into vaccum. Then the oil really started circulating and the smoking stopped. So I'm gonna try it again after dinner with the braided line and see if that works. I've never heard of someone with a breather filter having circualtion issure but who knows....

No no crankcase is not bad. I typed that wrong. My point was that those breather filters cause problems with the crankcase ventilation system and how its supposed to function properly. I need to stop drinking before the sun goes down.

So would it be bad to hook the PCV hose up to the intake manifold? Thats were I put it and the oil is definately flowing but there is a horrible vaccum leak sound from the engine bad. It is very loud but there are no vaccum leaks and it seems to be comming from the oil air separator....
Well hooking you Breather filter up to you Manifold will build boost in the breather the min you get on it... It really sounds like to me that your rings are starting to go and your losing compression into your oil pan causing this pressure to back up your oil return.. I have seen it all before...
I suggest doing a compression test first and seeing where your at.
Whoa... My rings? The engine only has 125K on it and I've never had any issues with anything...I guess I'll do a compression test tomorrow. I just really dont understad why I have to physically suck the oil from the turbo back into the oil pan.....something is wrong here.
The problem is where you put the return, it needs to be next to a main cap in order for the oil to drin because with the engine running and the crank spinning if your return hole is near a crank counter weight then it will prevent the oil from entering the pan. I have a Procharged 383 and in the instructions they tell you to drill the return hole next to a main cap for that reason.

When the engine is off the oil level is right up to the very top of the pan. When the engine is running the oil level will be lower
but when you're under hard acceleration just like every time the motor is under boost the oil will flow to the back of the pan most likely submerging your turbo's oil return line again. This makes tapping anywhere in the oil pan for your oil return line a problem.

Having a functioning PCV system will defiantly benefit you. Be sure to use a check valve if its being plumed to the intake manifold to avoid boost pressure being forced back into the crankcase, also a catch can or some sort of a inline filter should be used to catch oil and vapors from clogging up the check valve. For the PCV plumed between the air filter there is no check valve needed but a catch can or inline filter is a must to keep oil and vapors out of the turbocharger, charge pipes and intercooler.
I really doubt anything is wrong with your motor, rather just problems with the turbo system. I have seen many turbo LD9's and it seems that 8 out of 10 of them have had these same issues from a improper oil return line and a non-functioning PCV system. On my car my turbo oil return line goes directly into the block and i also have a functioning PCV, i have never had any of these issues with my set up.

Okay so what your saying is to just go ahead and plum it into the manifold but use a check valve and a filter... That will I'm sure work fine but when I start revving up then the vac will be near 0 and the oil will back up again. Won't that be bad for my turbo seals?
Re-route your pcv hose from the manifold to the intake pipe on the turbo. This will cause your pcv system to be under vacuum all the time and there is no need for a check valve. Make sure you plug the hole in your manifold. I would also recommend a catch can in line with the pcv hose also.

How can that many cars on here have this problem and no one has ever mentioned it. I have read a ton of stuff over the years I've been on here and never heard of anyone having this much trouble. It seems to me like the only way to fix my problem would be to tap the block, (Where would you even tap it at? Skilz?) Or to rig up some sort of pump to pump the oil back into the engine from the turbo and both of those seem like way too much trouble....I cant help feeling that there is something wrong, either with what I've done or on my car beforehand that is messing all this up....I am so lost right now as to what to do with the dam thing.

Your joking right? I remember a really long a$$ disscussion about this at one point, and as well, I know for a fact that I myself have mentioned it in probably atleast 10 different threads with people saying the same thing, "I am having oil burning issues with my turbo, blah blah blah"
No, I know that people have trouble with burning oil from there turbos all the time, but in all the threads I've read its usually bad turbo seals or need for a restrictor or something, not due to too much pressure reverse-feeding the oil return which is mounted at the very top of the pan... There are at least 250 people on here with turbo j's and quite a few of them are 2.4's and somehow for them the oil must drain properly just from a simple gravity feed line into the pan.

Plenty of people have mentioned it. I know personally close to 15 people who have turbocharged LD9's here in Michigan over the years that have had these same issues. For pics of my oil return check my cardomain page.
BTW, i like the pump idea.

Okay, well I guess I must just not have seen some of those, Oh well, live and learn. I've since decided to go with the pump idea. I found and bought a turbo-specific oil scavenge pump. It is sold mostly for remote mount turbo setups and the one I'm getting is made for custom turbo Porsches that need to mount the turbo in an odd location. I already ordered it and it should be here in a few days. My new question is this: Were should I route the return line to when it comes out from the oil scavenge pump. I guess I could just still connect it to the hole in the pan, but then I'm forcing oil into existing oil. What about running it to the timing chain housing such as through the vent tube on the front? I figure thats were the oil is normally put in anyway... any idea or comments?
Timing chain housing should be fine with a pump.

Cool, thanks. Im really excited to get it on the car and get this thing going...I haven't even driven it yet and I'm already addicted to boost!
Yeah I think its gonna work great. Here's the
linky to the pump I bought....
I'm with these guys

If all that doesn't work, then move on to relocating the return.
but that's just imo
