tornado_735 Posted June 25, 2010 Report Share Posted June 25, 2010 Tonight, I was bleeding the brakes on the GP when the rubber line blew off the fitting and shot brake fluid everywhere. I took out the airbox, MAF hose, etc. to clean up a little bit. When I picked up the MAF hose, I heard liquid inside the little plastic chamber thing on the bottom of the hose. I took it outside and flipped it over, and what appeared to be oil poured out of it. It didn't really smell like anything, and the viscosity was about that of motor oil. There was no oil coating inside the hose and the butterfly valve in the TB was nice and clean, so whatever oil was in there appears to have been in there for a while What might cause this?

RobertISaar Posted June 25, 2010 Report Share Posted June 25, 2010 MAF hose? why does everyone seem to think their 94-95 3100s have MAFs? and yeah, that's due to your PCV sucking up some oil. more or less normal, but a catchcan would stop it from happening. oil likes to soften/deteriorate rubber....

I know my 94 doesn't have a MAF. What the hell is that hose that goes between the air filter and the TB called then?! Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted June 25, 2010 Report Share Posted June 25, 2010 GM's term for it is "air intake duct" Quote Link to comment Share on other sites More sharing options...
pitzel Posted July 20, 2010 Report Share Posted July 20, 2010 The oil isn't exactly harmful. Simply discard it like you would any other used motor oil. In fact, it could be said that a little bit of oil could help to attract the dust that manages to make it past the air filter. And it keeps things inside the throttle body lubed up nicely.
