I'm using the mopar performance pan bolts with the litte blue treadlocking compound on them and they are not bootomig out.
I will reorder a set of your gaskets and try again with a 1/8" bead of RTV silicone between the timing comer/ rear main seal retainer and the block. I guess I do the same between the pan and the Gasket. I think it's the 5th time I pull the pan this summer.....
