Case gasket elimination
I have a friend who keeps having the Briggs case gasket leaking issue. First one at about 100 hours and cracked rear cover. Second leak about 150 hours later. Now about 150 more hours another leak and another cracked cover. I was told you could machine the timing gear and cam to eliminate the gasket, is this correct? Or do you machine the cover for the clearance for the cam and just do the gear for the crank end play?

Re: Case gasket elimination
Also has anybody tried welding up the case cover? It has a crack on filter side at the bolt hole with the dowel pin.

Re: Case gasket elimination
I know different folks do it differently but I machine the crank gear and the cam boss in the rear cover. Then I deepen the oil feed groove and chamfer the edges. To save headaches I would grab a new cover

Re: Case gasket elimination
Pokey I think it's a 2011 or 2012 GTR. What other issues should I look for? Will, do new covers come with the proper clearance to go without a gasket or do you still have to machine the gear and the cam boss in the cover?

Re: Case gasket elimination
The new cover still need work. It's the blocks that are cut deeper on factory wet gasket motors

Re: Case gasket elimination
Thanks Will for the info. Pokey I saw where you posted on a thread a while back about some parts on a dual rig that had sunk. Do you know if he has a rear cover for sell that is good?

Re: Case gasket elimination
Has anyone used the permatex OPTIMUM GREY? I was looking at their web site and it looks better the the ULTRA GREY. It says OPTIMUM GREY is up to 15% more flexible than ULTRA GREY and delivers 40% higher temperature resistance while maintaining outstanding resistance to oils, coolant, and shop fluids. OPTIMUM GREY combines the maximum torque load and vibration resistance capabilities of ULTRA GREY with the maximum temperature range of ULTRA COPPER.
