Industrial Injection Turbo Leak

Industrial Injection Turbo Oil Leak

Well I've found at least one other person with this issue and now that I have a replacement turbo leaking oil between the cartridge and the turbine housing just like my first one, I'm thinking II may have some issues. If you have a Phat Shaft or SB Industrial turbo, do you mind going to look between the turbine housing and the cartridge for an oil leak? I wouldn't have noticed mine but when I was crawling all over mine after a head stud install, I saw the leak. I've went as far as cleaning up the leak and using masking tape around the oil supply and drain lines and aluminum foil around the turbine housing to confirm the oil isn't coming from an external source. The truck doesn't smoke at all and the turbo doesn't have excessive endplay. I haven't measured crankcase pressure but the alarm hasn't triggered and the truck only has 30,000 miles so I can't imagine that being the issue. The crankcase pressure is routed right off the valve cover to the atm.

I noticed my first oil leak on my first turbo around 8 months or 2500 miles after installation and the second replacement one started leaking around 300 miles.

The turbo I have is a SB 62/74/14 with stock CP3 and Stock Injectors.

thanks for looking guys

I have a Silver 66 with the exact same problem. I purchased it in March of this year along with a 3rd gen manifold and noticed the leak a couple months ago. I sent it to Industrial Injection for a rebuild. They said nothing was wrong with it but they rebuilt it and shipped it back. As soon as I put it back on the truck the leak was there 15 minutes later. I sent it back to Industrial because they were confused like me. After putting the 2nd rebuilt turbo back on the truck the leak was there again. Industrial Injection has been working with me trying to figure this out but no luck so far. They sent another drain tube and gasket for me to try and it did work for about an hour but the leak eventually returned. I'm clueless. Any help is greatly appreciated. Thanks

I've heard through the grapevine there is an assembly issue of some kind on this.
wow i as well have the same leak !!!!! was just about to do a search but found this on the fist page.. i as well changed the the oil drain gasket and still have the leak smh.

Are you guys getting smoke at high boots ? I'm not talking about black smoke.

I'm not getting any unusual smoke. What color is the smoke? How long have you had the turbo on? Is your truck an 08? If you wipe the oil away how long does it take to return? Sorry for the questions but very curious about your situation. So this makes one more person we can add to the list.
Industrial will probably tell u to pull the exhaust off and look for a wet turbine wheel. Mine and JP's were both dry but there's still oil leaking somehow.

How old is ur turbo?

Truck is an 2007.5. had the sb in the truck since april 2013. the smoke was not blue,white or black more like a gray.

Not sure how long it takes the leak to return. Would you want me to check at a idle or driving the truck ?

i will pull the exhaust off later in the week to see if its dry or not .

You put yours on the truck almost the exact time I did. Please check after you take the truck for a drive. I can wipe it clean, drive for 15 minutes, then it returns.
What is the atm? I'm at a loss.
Mine doesn't leak under idle conditions but it only take 10 mins or so driving to make the leak appear

High boost conditions seem to make it worse
Looks like an oil seal thats breached, could be high crank case pressure or manufacturing defect. I can remember ever doing a warranty repair on one though.
My truck only has 30,000 miles so I have a hard time with the excessive crankcase pressure but do understand your point. Mine is routed external to the atmosphere though a 3/4 Heater hose instead of routing back to compressor inlet.

I haven't had a code for crankcase pressure- do u know wha that alarms at?

I removed the existing crankcase breather filter and ran and it still leaked so I don't think it's clogged or full or oil creating high crankcase pressure

I did the exact same thing. My truck has 70,000 miles on it.

I'm not sure honestly, but thats typically the #1 reason for oil seal failures. Take a video of the truck at idle with the oil fill cap off and post it up when you get a chance.
FYI having the crank case vented into the intake doesn't harm anything, having that vacuum on it is better than letting the pressure build up and push its way out. Only time you'll have an issue with crank case oil vapor is when its mixed with soot from the egr, then it makes a sludge that gunks up everything inside the motor.
Crankcase psi we are talking about is from windage of the internall components. Not necessarily bad it happens. You need to be able to suck that back into the motor as to create a vacuum on the crankcase. The windage is causing the oil not to return into the pan properly, causing the seal to fail. That's why at boost it seems to be more. Put a filter in line and run it back to the intake. Turbo may or may not quit leaking now because possible damage again. I have seen this on supercharged and turbo'd gas motors also.... I sold 3 of those turbos around that same area of the year but all went on 5.9s which the crankcase vent is plumbed different. I don't believe this is II's fault.
I'll try rerouting back to compressor inlet

I'll try it if you get good results. Maybe that has been the problem this whole time????:confused013:
