With that one piece gasket do you use an rtv or just bone dry?The four-piece cork and rubber oil pan gaskets for two-piece rear main seal oil pans suck.
The one-piece rubber gasket for one-piece rear main seal oil pans is far less fiddly and leaky.
If you're wondering which to order, and your GMT400 has the original engine, it's the one-piece rear main seal oil pan.
would you put dabs in the corners on the block then gasket then another dab in the corner before putting on the pan or put the gasket on the dry block and the dabs on top of that. Thanks for the responseDab of rtv in the corners of where the timing cover meets block and rear main meets block. Dab meaning a goober slightly larger than the size of a pea. And don’t over torque the bolts - that’ll distort or squish the gasket out and it’ll leak.

Thanks. Nice plane by the wayI did on both sides of the gasket just for insurance. So far no leaks in about 3 months give or take.
