Maybe you could swing by your local tuner shop and see if they can connect their external O2 sensor to your exhaust for a small fee?

It could be a domestic or truck or any tuning shop in general.

It won't be accurate until about 1500+ RPM but they can rev it up to say 3K or 4K RPM and hold it steady there, it'll be accurate and you can compare their readings to yours.

 

I just took off the throttle body and boy is there a lot of oil in the intake. That means oil in the combustion chamber and the exhaust and on my bumper. Not saying this is the sole reason for the soot as it is definitely running rich too. I have a catch can but I have to make a bracket for it. I might just buy the kit from radium. I guess 10psi at 11:1 compression causes quite a bit of blow by.

 

What current catch can/crankcase venting are you running now? Some blow by is to be expected but there shouldn't be a ton of oil either..? Do you notice the oil level on the dipstick going down?

 

I am running the oe pcv system with a filter where the breather that normally connects to the charge pipe is. I am working on a catch can setup. I think the o2 sensor was bad because I am getting richer numbers now that I replaced it, I think the soot on the bumper is a result of boost + extreme richness.

 

Not in my case. Not in many cases. Something is off.

 

Yep I agree. If you look at my build thread you can see how I have my catch can setup vented to atmosphere (that way no blowby makes its way back through the intake). There are many people that swear you need vaccuum on the crankcase though and they don't have a problem with blowby. The problem with a thread like this is it could be a combination of multiple things causing the problem. If you have smoike/oil in the intake it could be engine issues, the turbo (seals going bad), crankcase vapors, tuning, etc. Hard to pinpoint things w/o the whole picture.

 

That’s exactly what I am trying to figure out. Running rich like it has been could be the sole cause of the nastiness on the inside of the intake. The soot on the exhaust could also be because I have bad valve seals or a bad turbo oil seal. I will do a catch can setup and see if the intake gets better. I am also rebuilding the head in the near future and will replace the valve seals.
