Haven't we ALL heard this
Blow by what?
Unless the engine is running in reverse I don't see how that is possible.
What kinda turbo are you running?
If the first pipe that comes out of the turbo is wet with oil. Its the turbo.

Yep i got the same problem with mine. Oil in piping and intercooler. Its your turbo. Did you run it hard right after you put it in? If so, than thats why your turbo is already bad. You have to break in a turbo for at least 1000 miles now matter how much you want to floor it. lol.

It's probably blow by, not the turbo. Blow by is caused by gasses built up in the oil if they are not relieved properly it blows oil past seals.
Do you still have the PCV system still hooked up?
The stock system sometimes is not sufficient in relieving the gasses sometimes.
You might need to hook up a catch can system. Search for catch can install or something and you will find your answers this has been covered a couple times before.

I explained it above. It has nothing to do with new or old turbo or motor. It's blow by a common problem when increasing HP on these cars. I have the same turbo and got blow by your turbo is likely not blow.
Search there is lots of detailed info on this.

There is nothing to breakin on a turbo. Maybe the bearings...but the shaft spins on a film of oil?

The oil pumped through the turbo's centre is contained by the shaft oil seals. No oil seals are perfect, and oil will always get past them and into the intake. Very slowly and over a period of time, this combined with the blow-by mentioned above will create a film on the inside of the post-turbo pipes.

Now would be good time to stop posting, because you don't seem to know much about the topic being discussed. No offence, it just seems obvious.

And cosidering how his turbo has 300 miles on it I would call anything coming by the oil seals unacceptable.

sometimes oil seals need to be broken in to fully seal, though i am no expert on the internals of turbos it could be part of the case. i have seen plenty of stock setups with oil in the intake piping and the cars had no problems, also on piston engines as well so it is not just a rotary thing. a small amount of oil is fine, puddles of oil means there is a crankcase ventilation issue or a turbo oil seal issue.

The oil in the ic is definately caused by blow-by. This is what oil catch cans are for and the subject has been well covered in many threads. You can either choose to vent the catch can to the atmosphere (not smog legal) or plumb it back into the intake before the turbo.

PCV system
Blow by
and Too much oil pressure are possible culprits.
The PCV one was covered. It sucks in at the TID so oil could enter through there.
Blowby prevents proper draining from the turbo and the oil starts pooling inside the cartridge which makes pressure...leads into next stuff.
The oil pressure one is what I had. The internal restrictor was removed during a rebuild of the turbo. The car would send a **** load of smoke out the exhaust.
The oil will exit through the exhaust first. It's a simpler path. If there is enough pressure then it will pass the front seal and enter the intake.
If you **** up the front seal enough you'll need a turbo rebuild.
IF you still have a PCV plumbed into your TID check it out. Is there oil after that?
Then check after the turbo...
If it's after the TID but before and after the turbo then it's the PCV. If the TID is clean but post turbo isn't then check out your turbo.

My TO4E w/ stock hotside never had any issues and I used to get a fair amount of oil in my aftermarket TID and a skim coat throughout the IC piping. Definately blow-by. You can get an inexpensive catch can on ebay.
BTW gents, since I have never installed one nor seen one installed, this seems like a reasonable option, but where does it get installed on an FC?

Im not sure about the restrictor on the feed line but i had it built by a professional rebuilder its the stock unit with different compressor fan and cover.. but i imaging if there was one on it from stock then they should have put it back in does anyone know if there was one on from the factory? and as for the smoke.. it does smoke alot but only sometimes i havent got it tuned yet and i think most of the smoke is from being to rich and having a new motor and all...but sometimes the smoke is oil i can tell from the smell so it does burn oil somewhere....why is the oil press so high is it ok that it go's up to 100 on the stock guage?.......And thanx im glad you like the headlights i bought a set of the angel eye headlights that are made to fit the 3rd gen and hacked them all up then made them fit over the 2nd gen headlight cover and did some welding and fiberglass work and about 40 hours of hand sanding and other work... now i have my own custom headlights....
