Thanks grossgary for the reply. The question was meant to be whether I need to place any sealant between the backing plate (the on held on by the screws) and the pump. From your instructions, it sounds like no which is what I figured. I will place threadlocker on the (cleaned/degreased) screws only, and replace the O ring on the block. About the front crank oil seal- is it possible to put it on after the pump is installed. I misplaced the one that came in the rebuild kit, and need to get a new one on Monday. I was planning to put everything together, and then install the crank seal later. Is is problematic to install the front seal after the pump is on the block? Thanks, Cliff

I am replacing the head gaskets on an 1997 EJ25 and took apart the oil pump as suggested by some guides. I think I should have left it alone now, since the screws seemed to be in solidly. My question is whether I need to use sealant on the plate with the screws that holds in the pump rotors, or just between the block and the pump? From the design, it does not look like it needs any since the oil can seep out the front anyway. Also, if you know it off the top of your head, what is the torque for the screws on the pump? Otherwise I will just torque them to something reasonable like 20ft/lbs with threadlocker. Thanks, Cliff
