leweymeister Posted December 13, 2011 Share Posted December 13, 2011 I have a e7-427 in a '96 Ch613. It has one of those rubber vibration-damping oilpan gaskets. The oilpan started leaking through the gasket, so I got a new gasket and new rubber washers for the bolts and replaced it like they said, taking care to clean the heck out of everything and make sure it was dry. It got a little better, but still leaked. I tried it again... This time I reused the new gasket because the book says they're reusable... it was worse. Any tips or tricks? I thought of using some of that spray gasket-maker... just a thin layer to seal 'er up. Haven't tried it yet, wanted to see if anyone had a better idea. Thanx.

leweymeister Posted December 21, 2011 Author Share Posted December 21, 2011 It's leaking all around the pan where the gasket is. I can't tell if it's above or below the gasket. It's worse towards the rear of the engine. Quote Link to comment https://www.bigmacktrucks.com/topic/22108-e7-oilpan-gasket/#findComment-94884 Share on other sites More sharing options...
Higgy Posted January 8, 2012 Share Posted January 8, 2012 Did you put a fat pea size drop of silicone at the four corners of the block where the flywheel housing meets the rear and the timing cover up front? If you don't seal those four seams, it will leak. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/22108-e7-oilpan-gasket/#findComment-97090 Share on other sites More sharing options...
Mackpro Posted January 8, 2012 Share Posted January 8, 2012 Make sure its not the air compressor to engine block gasket leaking, I have seen those leak and make it look like the oil pan gasket was leakin. And like Higgy said, silicon where the front timing cover and rear flywheel housing meet the block.
