Few questions under oil pan

[mudbog42]

Well I've been getting a knocking noise but only after the motor has fully warmed up and then oil pressure gets real to about 15 PSI, (its at 60 when cold) so I pulled the pan to look underneath and see if I can't see anything.

I've put on a new oil pump and screen already since I have it off and from what I can see everything looks good under there but I could be wrong

The only bearings that seem to have any play are the rod bearings and its just slight movement forward and back which I believe is normal?

Just wanted to know if there is anything in specific I should check while the pans off.

Oh yeah its for a SBC 350 and are you supposed to use silicone on an oil pan, because I know your not supposed on a transmission pan

Thanks

What do the bearings look like? Might want to plastigage them for a quick check and see if one is loose.... Hard to tell anything with the caps all on....
