excessive oil - self inflicted pain

[HelmetHead]

A couple of months ago I bought an 87 930 which was neglected.
(intro link Long time coming! My 930)

After purchasing the car, I began to notice smoke out of the exhaust and further investigation determined that I was blowing oil through the intercooler/intake....well, it has to be the turbo seals right???

So I order a new K27 HF S from Kevin and get it installed...follow all the instructions for pre-oiling the turbo before firing the engine and then button it all back together. I notice a small leak on the turbo sump flange and fix it....well, I lost some oil in the process of fixing the leak.....So some genius (un-named to protect the innocent ) overfilled his oil tank.

After puking a healthy amount of oil on the garage floor, I realize my mistake and drain some out and refill to dip stick level while at operating temperature.

My problem is I still see what I would consider a huge amount of oil collecting on the tins and dripping/pooling on the floor. Both inlet and outlet oil lines to the turbo are dry? The oil appears to be blowby from the turbo outlet neck to the tappered aluminum tube which hooks to the IC inlet Is it possible that i'm still flushing excess oil through the breather lines connected to my intake piping? Could I be generating too much crankcase pressure (not sure if this is even a possibility?) I thought I did a pretty good job cleaning up the over filling issue??

Has anyone done anything to re-route the factory breather tubes on efi turbos..if yes, pics please?

I am really concerned now that I might have replaced the turbo for no reason other than a bit more low end boost (which isn't a bad thing)...but the oil pooling has me stumped.

help please.

Are you sure that the oil line fitting going to the turbo may be spitting oil. I've heard of some lines in that area leaking. If you can wrap a white cotton cloth or towel around the fitting area, it might give you a clue if it's from there. Of course clean up the area first on the tin and IC pipe to get rid of any earlier deposits.

Dave,
Thanks for chiming in. I will try the cloth towel around the oil lines....the upper supply line is new braided line so it could perhaps be at the fitting.

I'll climb up under the rear end and report back in a bit...

You should also install an oil-catch can on the breather lines. This will "catch" most of the oil and blow-by vapors from the crankcase, if that is indeed from where it is coming. If it fills up quickly, you have too much oil or excessive blowby.
You will also be doing a good thing by keeping that gunk from coating the inside of your intercooler (making it less effective) and keeping your combustion chamber from developing excess coke (which causes detonation).
Good luck,
