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
