Has this turbo gone bad?
Just went to replace my stock intake system and I noticed the I/C pipe going into the intake manifold had some oil, uh oh, me thinks! I then get to the j-boot and oil drips out of it! I **** myself and then clean up the oil. The impeller shaft has no in and out movement but plenty of up and down, it appears that the blades could contact the housing, but the blades look good and intact.
This is a new Garrett T04E/50 with #8 hotside. It has less than 400 miles on it with no track days and zero time above 14 psi. The turbo water pump has always worked and the airbox, maf, and boot are well sealed. How could oil get there? Is any amount of oil at the inlet acceptable? Is any impeller movement of this type acceptable?
I need advice if I need to seek service for the turbo and hire a hitman for the vendor...just kidding on that last part.

If the propeller moves up and down freeley then you need a new turbo or have your turbo rebuilt. Also check your pipes going into the intake J boot for any oil coming out of them. But most likely you will have to have your turbo rebuilt. I had the same situation. Cost $350 for my turbo to be rebuilt. The oil that gets into your intake boot comes from one of the pipes going into the intake. This is the big pipe going into the intake. This pipe is then connected to the crankcase breather, which if it becomes pressurized, it will dump it into your intake.
What i did was send my turbo in to be rebuilt, and then found out the problem about my crankcase. So I bought a Remote Crankcase breather which solves this oil problem.
Also, Did you resently change your oil? The oil that i was using was Valvoline Max life. Then i changed my oil to full synthetic and this really helped with my rings.
So I hope this helps youre situation.

Oh man, I am pulling my new turbo because of that same problem.
I have 3700 miles on a TO4E 60 trim #8 turbine. I installed it with a new rebuilt engine and the car has smoked ( blue oil )since first start up, thought it might just be the rings not seated. Smoke got a little worse untill Friday when I noticed the boost not building correctly and I had blown a intercooler hose off, oil went everywhere. Removed the intercooler and drained out 4.5 ounces of oil and could see what looks like 2 more ounces in the compressor housing and the impeller can be moved up and down.
I am down to the last bolt and it stripped on me, letting some JB Weld and allen wrench setup now.
This sux new parts going bad so quickly.
I hate to tell you bad news, but I think we have something in common. I hope not BUT...
I am getting to know all of these parts too well, don't even need notes or labled baggies anymore.

If they do turn out to be a turbo problem, please post the supplier so other listers don't fall victim as well. I have plans for an upgrade for next year, and would like to know whose turbos are problematic. Thanks

I just got a new to4e 2 weeks ago. I pulled it out of the box, felt the amount of radial play that it had, and sent it back the next day. I also went and checked a new to4e turbo my friend just got for his track car and it was the same way. He is also sending his back. I should be getting mine back today or tomorrow and I'll see if it looks any better. Maybe there is a bad batch of center sections?

Hey guys, I appreciate all the feedback on this so far.
I bought it from Huntley Racing. As stated eariler the oil may be from the crankcase venting into the jboot, that is some good news. How do I resolve this?
I need to get more specific on allowable movement with the turbo shaft. With some pressure I can move it up and down a few .00's, I am guessing. I can also hear and feel slight 'cliks' when doing this.
Why are we paying for rebuilds on new components???

Some oil in the intake is normal, depends on the condition of your rings as to how much blowby you will have.
I am installing a catch can from Lindsey Racing.
Not sure how much play is too much, I have the clicking noise when I move the wheel also.

Just talked to Kevin at Majestic, most willing to help solve the problem.
Kevin asked me to call him when I get that last stubborn bolt out ( in the next few moments I hope )
I will post any info.

This list is great, I have been enlightened!
Some very useful sources off-line suggested that we run oil through the turbo before checking for play. I will try this tonight and see if I can measure with a guage.
Thanks for the contact...Kevin was very helpful. He reitterated that almost 10 thousandths was acceptable and always lubricate first! How did I forget that one!
Popular census with the oil is that is is comming from the crankcase. I have @200 miles on head rebuild and a few suggested that not everything may be seated. The oil may disappear as seating occurs or I can install something to 'catch' the oil.
Anyone have a ideas on an easy upgrade on the CC vent???

The thing is, when i installed my Lindseyracing catch can, I never got one drop of oil in it. And this was immediately after i reinstalled my rebuilt turbo, crankcase breather, and changed my oil to full synthetic. So, I now have no more oil in my intake or blowing into my turbo.
So overall, the crankcase breather looks great in the engine bay and also vents the crankcase to a remote container. However, @ $150.00 it can set you back a bit. I would definately recommend this to anyone with a oil problem in their intake.

The Garrett was "customized" by Huntley, before that I believe it came from Majestic. I never saw a "T" on it, I thought it was a Garrett center section. It has standard bearings.
After running oil through it last night the play on the shaft was significantly reduced. Yahoo!
Now I have to look at that Lindsey CC upgrade or a cheaper/compatible unit.
