Colt Posted 3 hours ago Share Posted 3 hours ago IMG_0193.mov My E-7 460 leaking oil from where the compressor mounts to the engine . It’s “bubbling” from the top side . Is this most likely a gasket failed ? I read oil is supplied by the accessory drive . Is there enough pressure there to make oil push or “bubble” out of the top? I figured if it leaked it’d leak out the bottom side . My mind was just thinking could it be a bad compressor pressurizing the crankcase . Hate to change the gasket and blow again. Here’s a pic . Any help appreciated, I claim to be no mechanic just a hobbyist/truck driver .

Geoff Weeks Posted 3 hours ago Share Posted 3 hours ago If you are pressurizing the crankcase, it will pressurize the WHOLE crankcase, not just the acc drive. Change the gasket unless you have massive blowby out of the crankcase breather.

Joey Mack Posted 2 hours ago Share Posted 2 hours ago When you remove the compressor, there is a metal tube in the center of the aux drive hub. It is not secured.. make sure you see it, and put it back in the hole in the aux drive shaft. It is the oil transfer tube. 1/2" X 1 1/2" long Quote Link to comment https://www.bigmacktrucks.com/topic/75057-air-compressor-question/#findComment-567366 Share on other sites More sharing options...
