Alright so I've started noticing a bit of oil buildup around my passenger side headlight, I started looking into it and have found a fare amount of oil in the intercooler piping as well as coming through the MAF and out my intake. Poking around I've come to think that my turbo could have bad seals in it. Is this most likely the problem or is there another thing that I could have missed? Any suggestions would be great thanks!
Oil in intercooler piping?

Turbo or lots of blowby...
A little oil in the IC piping is normal, dripping out the intake is not...

I'd say lots of blowby or turbo, personally. 
Start the car and pull off the oil cap, check how much blowby comes out.

If it's that much blowby he's just going to fill the catch can as the rings are shot...
Compression test will show if it's blowby as well...

keep in mind that if the timing belt tension pulley is tq'ed to much and the #1 cylinder does warp, it will cause blowby with minimal affects on compression.

I have taken off lower IC piping before, I had a nice little stream of oil that came out. It was a stock '87 Supra with 150K though. Oil in the IC piping, totally normal, if your turbo is goes bad, it can also push oil out of the bearings and send it through. Blow by from your engine as well can certainly do this as well.
Blowby just impedes the Turbo's drain and will cause the turbo to flood and smoke in the exhaust not introduce Oil into the inlet tract.92TealSupra;1162791 said:

If the seal is borken on the compressor side, oil can leak into it. Then the oil in now in the intake track. :icon_surp
Ever pulled a turbo apart and rebuilt one?......
If so describe this mythical/magical "seal" please

* well considering it's not a seal I just put that so ignorant people don't bitch. it's a bearing. Turbo''s do not have Seals*** and yes I have torn apart plenty of turbos..

Behind? Lol so you are trying to say the bearings on the compressor side don't go bad and won't put oil in then IC piping? Well okay? Yet i am still behind right? You're the one that will bit responde to the question, but you can tell me i behind?
I al not trying to be an ass here, just saying that this can happen.
Every single post you make just confirms you have NFI and are just parroting bullshit you've read on the internet.
I asked you to describe the seal in a Turbo and seeing how you've dismantled many of then according to your post I'm still waiting.
YOU come back with some garbage about no seals only bearings again confirming my suspicions.
Seriously just give up you're embarrassing yourself.

How about if you do find oil in your intake, or exaust. One contrebutor for this could
be inadiquite oil drain back from turbo. As the "seals"(o-ring) are made to deal with
preasures from the charge side and are not able to controle oil preasure from the bearring side. Resrticted return passage from sludge or carbone build from possable hot shutdown.
If you have infact found the source is the turbo. But in a most cases it would be engine
blow-by. And could be valve seals also. (spell check on the fritz, sorry) Muzy

Bullshit wow. Man you have serious issues getting all "upset" on here, and you're only excuse is, I have bullshit and I do not know what I am saying, and I get all my information from the internet? When you have something useful to say that's another thing.
When you have something stupid to say keep it to yourself. You're now trying to make me look like total garbage here. I am aware your " Social status" at Supramania, and I do not want to demise you or make you look bad, and I am sure you do not want to look wrong bad at the same time.
The fact is if a bearing wears, is pressurized, and ( or) is restricted oil from the bearing can let oil excape it's oil route and go into the compressor section. That is all my post was about here, and yet you seem to bring your knowledge in and make me look incapable of posting?
Please don't demean my character with saying my posting is garbage. You act as if I have no clue about the ct-26's, the 7m, or any electrical about the car. There are some questions I have that better my learning, and maybe to some they're so easy they could have be figured very quick for them. I don't like confrontation on here, I see there is no use for it unless something spirals out of control.
Good day, IJ.
With the above rambling garbage post you've yet again proved you have NFI just give it a rest.
I can't be bothered disecting and correcting your posts but it's obvious to anyone here that has a clue that you don't.
As for the wearing bearing "leaking" you do know that the plain bush style bearings "float" so are pre worn and it's the job of the 3 different types of seal in a turbo to control the Oil frow through the CHRA (none of which you've been able to identify or describe as asked other than "the beaings seal the oil")
I'm not trying to "demean your character" you're doing well enough on your own each time you post.
rememeber this?

It's because IJ is correct...dazzle with BS is not going to work in this case.
The CT26 (along with a lot of vanilla variety turbos) uses journal bearings that depend on oil flow...they are a hydrodynamic bearing. The oil flow under pressure keeps the turbo shaft and bearing surface from touching...it must be constantly replenished. That's why the oil is allow to exit from the bearing ends and is drained to the pan.
The bearings by design "leak" and it is not possible for them to act as a seal.
