I installed a Racor 4500 CCV oil catch can about 18000 miles ago. This winter I failed to drain it until I noted a sudden drop off of ~2MPG. After the truck had sat overnight in near zero weather, I found the red bypass indicator was up and the filter element was fully saturated with oil. There was also a large block of ice inside the cannister!

After cleaning the unit out and changing the filter and O-rings, I was left to wonder how much oil, if any, might have passed into the turbo intake?

Does a process exist for inspecting and cleaning the turbo fan? If yes, can anyone point me to a DIY reference?

Thanks in advance.
Peace/Out
Stay safe

Cleaning the turbo/compressor is not the problem, the problem is the oil flowing through the turbo and into the intercooler hoses, intercooler, and intake. Unfortunately, there's not an easy way to clean out the intercooler because it's a giant pain to remove. You could pop the hot-side (passenger side) intercooler hose off of the intercooler and look inside to see if there is oil pooled in the ridges of the hose between the metal rings. The quick connect fittings are easy to get off once you know how. This slightly annoying video explains it pretty well.

Hey guys! Video guys not at all annoying guys. Think maybe guys, it's a Bavarian guy speaking English as a second language guys. Using "guys" where we might use "umm" or "er."

Thanks for the heads up and the demo video of releasing clips without damaging a $150+ tube! I'll inspect it to see if it looks like any oil mist got through.

Thanks again umm.....................................................................................................guys (lol).

The Racor is the best catch can money can buy - I have a Provent and covet your catch can. Don't worry too much about this. All that gunk in the can is gunk that did not go through the hoses and intercooler :LOL:

I do wish the intercooler had a low spot with an accessible drain plug. No doubt it catches it's fair share of condensed water and oil. I suppose it is not hurting anything sitting in the bottom of the intercooler though. The oil might even serve to keep it from corroding.
