AO Separator assessment
I did the throttle body cleaning and cleaned out the intake cross tubes etc. I noticed oil coming out the ribbed tune connecting the AO to the Throttle body assembly. Is this an indication that AO needs replacement? Is there another way to check/verify. I read somewhere that unscrewing the oil cap with the engine running would confirm it. Inputs appreciated. Thanks.
