Ok I might know the answer....but I don't know??? I have oil in my turbo and blowing lots of white smoke.
Oil is in the turbo exhaust portion, here is a pic.

It might be I have the oil drain line to low on the block.....I have it in the oil pan spacer. I might have to drill the block higher, is this correct???

 

Is there any play on the turbo's shaft? What setup is this?

 

It's a Garret GT35......Oil lines aren't leaking, but oil is in side the exhaust portion. I think it might be the oil return to low on the pan, t might be backing up in the return....not sure any help??

 

bump

 

^^its a turbonetics kit........bump

 

Okay, I just understood what you were saying. (I think) You're saying he's got the GT35R mounted to the turbonetics piping?


I would focus on making the return line straighter rather than higher, or changing to 45 or 90 degree elbows on the tap and fitting out of the turbo.

On a GT35R garrett dbb turbo they also recommend a -4 oil feed line and a .035" restrictor unless one is built in. You also want at leaset a -10 return.

 

Are you using a pan spacer or an APS style pan with the ports built in?

Edit, NM saw in your OP that its a spacer. I would look elsewhere for the source of your problem. There are lots of people running spacers with no issues on this kit. Although like Taurrann said make sure your return line is not kinked, twisted, etc. What size is your return line?

 

The return line is 5/8 ineer diameter.........straight out the turbo, straight down to the spacer, which uses a straight 1/2 npt fitting. I believe the fitting on the turbo has the restrictor, but I will have to further investigate this. So you guys don't think having the return line that low would be the issue?? We are going to tap hight in the block today, to see if it helps, but now I think I might be wasting my time. There is alot of oil in the housing, and and we see no leaks on any of the fittings. LMK what else you guys think it could be???

 

I'm not guaranteeing that your return line location isnt the problem, but I think its probably unlikely given the number of people who run a spacer return line setup on the Turbonetics kit without issues.

Your return line is properly sized as well, so thats not the issue. I would investigate your feed line, and see if the restrictor is there.

 

ok thanks let me see what I can find

 

What about crankcase pressure? How's your oil pressure gauge read? How do you have your crankcase plumbed?

 

No plumbing in crankcase????
The turbo has 1 inlet, 1outlet for oil, then 1 inlet, 1 outlet for coolant.

 

The oil is going back into the crankcase. The crankcase pressure can increase if it is not properly ventilated, leading to all sorts of problems. Generally speaking the PCV valve and driver side inlet will allow for ventilation - but if you've changed "the plumbing", particularly on the driver side (the side without the check valve), then that could be a source for problems. Most turbo kits address these issues but if you install a check valve backwards that can lead to big problems... What kit are you running? EDIT: Just saw TN - I'm not familiar with how that kit addresses stock crankcase ventilation.

 

Lets not overlook the obvious by focusing on just the peripheral stuff - how many miles do you have on this turbo? And you never answered the question as to whether it showed any shaft play. The turbo may just have a failed seal.

 

There's is no shaft play.

 

Where Turbonetics tells you to tap the oil block, its only about an inch to inch and half higher than where the oil spacer tap is. Since Turbonetics doesn't tell you install an oil pan spacer, how is it different to tap the original oil block pan?

 

It's either resistance to oil flow drain, too high oil pressure supply, or weak oil seals in the turbo. Take your pick and try to address...

 

We wil try to see what happens tommorow now......we change the fitting at the spacer to a 45 degree to allow more gravity flow. As for crankcase pressure........not sure how to address that????? We have a oil catch can that ventalates to open air.....I would think that would be plenty.....the turbo is new 0 miles on it. Well about 20 now.

 

Bump!

 

My old turbo analysis from Ed

"Well it seems that your turbo has suffered coking ( oil residue buildup ) on the components from either hot shutdowns and or viscosity breakdown high engine temp. The components had that builup so start using nothing but full synthetic oil. I use motul oil in mine and have my turbo timer set to 45 seconds."
