ea82 oil pump ?

[ivantruckman]

my oil pressure tanks at idle, also its definatly leaking from the oil pump,so its front engine seal time, as well as new t belts, idlers etc. my question is, if the oil pump isnt scored or worn do i need to replace the pump or just the gaskets. my manual is veague on this matter, this message bord rocks.. thanks in advance

Almost all Subaru oil pressure gauges read zero at idle.

The o-ring kit from the dealer is fairly cheap.

Of course, you can read more about it here.......

in general resealing the oil-pump solves most problems (TOD and leakage). some people have experienced issues even after doing the reseal, in those cases a new pump would likely cure things. be sure to replace all the oil pump stuff - new shaft seal, gasket (mickey mouse gasket) and o-ring. have a 1" socket ready to get the nut off the oil pump pulley. it's a 12mm nut, with the oil pump out of the engine, use the 1" socket to hold the rotor on the back steady while you knock it off. works wonders.

 

there's also the front crank seal right above the oil pump, they can leak severly as well, so if you suspect a leak in that area plan on replacing that as well. it's really annoying to replace, not much room to get in there and work with it and tap the new one in place. take your time. and use SUBARU only crank seal. i installed a crap Fel-Pro seal a couple weeks ago for a friend. it was wobbly and did not want to seat straight. finally got it lined up and pressed in after multiple tries. it ended up leaking, i replaced it with a Subaru seal and all is good.
