Im saying that because we turbo'd my friends car and the turbo sat low like that and the line was about that long and he had the same problem as you. the oil was all frothed up and wasnt flowing well. My understanding is it needs to be a certain length so it can liquify ( i guess) again so it flows better.

but im not sure what you can do since the turbo sits so low.

 

had same prob with space on mine actually looks like you sholdnt have a prob with your return line ive seen worst anyway if ya cant get it to work just go hard line 1/2" or 3/4" copper pluimbing pipe works excellent couple 90s and 45s and your in it flows good

 

You shouldn't havea 90 comming off your turbo. I talk to lots of people at precision and they dont recomment anything but a 45 or a straight out fitting. According to them a 90 will jam up the oil flow.
Also what size feed are you using?

Right but look at how low the turbo sits. If he uses a 45 it will angle the line way low and he'll have to loop it up causing a low stop which can also kill the turbo.
Jason where is the smoke comming from? does it only smoke when you hit boost or also when your idling?

 

reweld the fitting on the oil pan lower

I know this. Look at the pic and provide a solution. IT is a -3 feed

Yeah, I am going to bring the entire piece in tomorrow morning and see what we can do.

Thanks man.

It is comming out of the exhaust definately. It has a slight....almost intermitent to none at idle.....and smokes intermitently under boost and during shifts

 

Me and a buddy are having the exact same problem on a brand new turbonetics t4! Its a t74 and we started it for the first time ever last week and the car was blowing tons of smoke even though it was reading a good air fuel. After letting it run a few minutes we look and oil starts dumping out of the compressor. Pulled the turbo and the exhaust housing is full of oil. Look in the oil drain line and its practically dry just a very light film on one side of it. We could not see any reason why it could have backed up. He sent it off to Turbonetics monday and we are expecting word back today or tommorrow. We missed a dyno appointment yesterday that took 3 weeks to get ! I would love to know how this happened, we assume it was a defective turbo. It hope Turbonetics straightens this out and it gets resolved soon.

Yeah, my setup was fine for about 30 mins of idle and about 6 miles of driving. I am going to pull the return in the morning and see what is up.

Thanks alot for everyones input.

hey blown, cant u take the upper 90 degree fitting off, and just put a straight fitting on? eliminate that sharp turn and have it come straight down and over the the oil pan. my help a lil more.... anyway good luck man.

THe problem is if I go with a straight fitting, the line will be lower than the fitting on the oil pan forcing the oil to return upstream instead of a nice gravity feed. Upstream flow....not good for an oil return.

 

Switch to a -12. Keep the fittings the same configuration, but switch to -12. Cut off the old Bung and have a new one welded on, perhaps just a tad lower too so you get a little more angle on it...obviously it goes without sayng that gravity is the only thing getting that oil back so a bigger line is a must when angles are real shallow. We had problems because our turbo was so far out and the angle on the line not very steep so the switch to a -12 cured the oil smoking problem.

i found that on the moroso panif you have the oil level up pretty high, it will smoke.if you take the fitting loose from the oil pan you will notice the oil level is above the fitting.i started running a lower oil level and it quit smoking.the pan holds an extra quart so a lower oil level would be no problem.i usually run mine just below the lower dot on the stick.
also,you should run a restrictor on you oil feed line.take the fitting going in the turbo ,weld it up and drill a small hole in the fitting to restrict the flow to the turbo.alot of people use a 4an line for the feed and you do not need that much.

 

I had that exact same **** on my old race car. Is that the moroso oil pan cause when I had mines I had the same prob. It can be 2 problems .
1 The oil return sits too low because of poor design on the pan
2 With the moroso pan it dosent give you the right reading on the dipstick so adding too much oil is a problem.

Either way you know the prob is the return is sitting below the oil level in the pan or the passage isnt allowing the oil to drain freely. I fixed my problem by dumping the moroso for the stock pan.

 

even with just a barb fitting on the turbo side? like if u eliminate the fitting so that there is more line to drain...

this may sound crazy from a guy who sells oil return and feed line on honda-tech

but get a 1/2" ID steel tubing, then get a pipe bender and bend it to where you have a good flow...then weld it to the pan or to a fitting that bolt in to the moroso pan.

I have a 1/2" fitting that is steel, so you can weld on side to the steel tube and screw the other 1/2" side to the moroso pan. Just cover the shipping I'll giv eyou one. I have literaly hundreds of them

also remember when you use braide line and fittings you may be runnign a -8 or say a -10 fitting but where the elbow bends the inside diameter isnt that big. i run a straight out of the turbo and a -10 braided line hose clamped to the pan fitting. your return is not direct enough. it will back up the way you have it. trust me i have been thru my share of oil smoking turbo setups.

 

FWIW:

The clubSi dude was using the Moroso oil pan as well.

 

I think you should run less oil and see if it still smokes. That would help to locate the problem more.

 

I contacted moroso before I started this thing and they said it will hold 5 quarts and be under the oil return fittings. Stupid fools. The pan will only hold 4.1 quarts before it reaches the oil return fitting. Hopefully that solves the problem.

Thanks alot for all your help!!

Now can you solve this one?

Are you kidding........ look at it its perfect!

What size is the feed line(top)? The return line looks fine, you are a little vague as to where its coming from, is it definatly the bottom of the turbo? It could possibly be that the top line is too big/small...... give me some more specs on the lines, and where exactly the oil is bruning from

 

welp, guess i shoula read to the end of this one....... sounds like you solved it

 

What size return line are you using? It looks like -8???

 

Have you thought about running a scavenge pump? Maybe the turbo really is just too low to get good flow back into the pan?

Edit: Just noticed you fixed it
