Jojo I have no real idea when the compressor went out it blow water out the recovery tank and truck ran hot cut off I clean the blow by filter which was full of oil moisture slug cleaned it out with carb cleaner and gas maybe that’s what was causing it to build up pressure to push the oil out of the little breather vent on the filter housing I’m not sure but I checked the filter again after it worked all day and no slug or moisture in the system now and no water in oil hopefully it continues to work til I can get some money together 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76478-2000-mack-rd688-e7-air-compressor-help/page/3/#findComment-594102 Share on other sites More sharing options...
