Oil Pan Gasket Question

I did use the rubber ends. There is way too much gap on the ends for me to feel comfortable with not using the rubbers.

I am having a real problem keeping the front rubber from popping out on one side or the other, once I get down to the final bit of tightening.

I'm working on a solution now.
Yeah. I've seen people fill up the grooves in the ends with RTV before. That's a LOT of RTV. It'll surely work if you put enough in to seal, but damn, that stuff gets expensive. lol
