OK guys I'm out of ideas. Above the right hand silent shaft drive gear there is a threaded plug. The case has an o-ring grove to seal the plug. I cannot get that plug to stop leaking. I have tried everything I can think of to get it to seal. This is a new front case/oil pump assembly off of Amazon. I tried at first to use the o-ring in the gasket set with a little silicon. That is how the old case was done. After about 30 seconds it started leaking. Then I tried the o-ring with a lot of rtv silicon. I ran the plug in until I had a good squeeze out of rtv and let it dry overnight, then ran it tight. Same leak. I then tried a fatter o-ring. Same thing. I tried an o-ring that fit tightly around the plug to ride on the lip before the o-ring groove. Same leak. I went and got a fiber washer for an oil pan drain ,still drips. I have tried all of these with both silicon and permatex 1 and 2. I can now change a set of timing belts fast enough for NASCAR but I can't get that stupid plug to stop leaking.
How much pressure is on that plug? When I start the engine cold I have 75# of pressure. Has anyone had this problem? I ready to use the truck for a target.
