macattack Posted August 23, 2015 Share Posted August 23, 2015 had my oil change last week and noticed that on one side of the oil filter housing there is a small nipple on the side closest to the cab. looks like either the hose fell off or the mechanic pulled it off for the oil change and did not put i back.any ideads where this goes to. i think its a vent.its a 96 mack mech e7 350.thanks Quote Link to comment https://www.bigmacktrucks.com/topic/41475-oil-filter-housing-top/ Share on other sites More sharing options...
alex g Posted August 23, 2015 Share Posted August 23, 2015 Without looking at mine I believe it vents back to valve cover Sent from my SM-G386W using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/41475-oil-filter-housing-top/#findComment-301175 Share on other sites More sharing options...

macattack Posted August 23, 2015 Author Share Posted August 23, 2015 here is a pic of the nipple off the side of the housing. looks like just a push on hose.i found a threaded hole on the side of the valve cover i am assuming thats where it goes.so can i add a new nipple at the valve cover and just push both ends of the hose on or should the valve cover end have a secured hose?thanks Quote Link to comment https://www.bigmacktrucks.com/topic/41475-oil-filter-housing-top/#findComment-301198 Share on other sites More sharing options...

460P Posted August 24, 2015 Share Posted August 24, 2015 The hose used for that is plastic fuel line, same as your fuel return. Quote Link to comment https://www.bigmacktrucks.com/topic/41475-oil-filter-housing-top/#findComment-301301 Share on other sites More sharing options...
