I have a lot of experience with the EA82T oil pumps but none with the newer T...Can I simply reseal this pump or does it need replaced? I have noisy (very) lifters. Other than that seams to run fine, no smoking, missing or hesitation. 1992 Legacy Sport EJ22T, 150K miles.

thanks

You can remove the oil pump, replace the o-ring and reseal it. You can also remove the backing plate and check that the clearences between the rotors are within spec.If that is good.....you probably need to replace the lifters. They may have been gummed up due to infrequent oil changes.
