Pressure check 3rd main. Model B
 

Hey all
Just looking for a little advice.
I am going to install a 3rd main oil seal In a Model B engine. The instructions say to pressure check the main bearing with oil to 10lbs.
I’m wondering what the best way is to go about that.
Thanks

I use an old butane tank rigged to put air pressure on top of the oil in the tank and force it into the valve cover. I have full-pressure engines so already have an inlet in the cover. Won't work on a Model A, only on B's.
