So, a while ago I used to work for this total DB of a man, we'll call him Justin for argument's sake. Justin knew a guy who just graduated from the local university, with a degree in engineering, and paid him to come up with a maintenance free solution to catch-cans for Subarus. They came up with this odd creature.







The unit replaces the factory oil cap. Two of the hose fittings take air from the CCV's (Subaru engines have one on each head) route it through a baffle system which condenses the oil, and drops it right back into the oil filler neck. The third hose fitting routes back to the normal routing. Basically it's a catch-can/provent that drops the oil back into the sump.

Does the CRD's oil system need to be under constant pressure at the oil filler cap, or would something like this work? I have one of the working prototypes without the DB's obnoxious company logos sitting on a shelf collecting dust. I have no issue fabricating an adapter to join it to the CRD, so that isn't an issue, just wondering if the CRD's systems are that different from your standard turbo gas motors?
