So, I pulled my supercharger to replace the leaking Charge Air Cooler. While I have it out, I decided to port/polish the inlet plenum and runners. When I removed the inlet plenum from the supercharger, I noticed a thin film of oil. Upon looking further, there was a LOT of oil film on the rotors and in the cavity. Also, inside the 3 cavities on the "hollow" rotor, there was sludge build up. I was actually able to carefully remove the sludge from inside the rotor in long solid pieces with a screwdriver. I did manage to clean everything out with some long foreceps, some carb cleaner and shop towels.

Questions:
- Has anyone else encountered this?
- Do you think it's possible that this is just 85k miles of oil being sucked in the intake?

Note: it doesn't have the nasty smell of the superchager oil, which is why I'm leaning away from it being an internal SC leak.

 

check oil catch,https://www.crossfireforum.org/forum...h-can-kit.html all sc engines do this by what i understand

 

Mine was the same. I have catch can also. I believe it is aluminum and Teflon paste. I installed new/used rotors in the old sc and scrubbed everything perfectly clean inside and out. It's come back again and I'm assuming it's normal wear from the sc rotors.

 

Thanks for the reassurance! Definately don't like that this is probably going to come back... it's a lot of work to pull all this crap apart to clean. Also makes me wonder if this catch can is really doing anything; It hasn't caught much fluid in it since install 1.5 yrs ago.

 

Were u the original owner??Woody

 

I've had it since 13k miles. So just about since the begining...

You should have seen the build up in the manifolds from the CAC leak combined with some of that oil!
