Fran3682821 Posted March 5, 2010 Share Posted March 5, 2010 I Just recently bought a 2007 Mack granite with a mp7. I am noticing some oil drops coming out of the vent pipe underneath the motor. I also notice sometimes only when I haul out the dipstick for the engine oil some traces of a grey scum in with the oil. I changed the oil about 3000km ago at a Mack dealer. And my antifeeeze level is not droping. It also seems that my engine oil level has not dropped any at all despite that I have some oil dropping out of the vent pipe and also a small oil leak coming from the front of the oil pan. I wonder If there could be some diesel fuel geting in the engine oil. Quote Link to comment Share on other sites More sharing options...
