torxxx Posted September 23, 2008 Share Posted September 23, 2008 well I have the chance to get a XT6 with blown head gaskets and a very ticky oil pump. so dumb question of the day... XT6 and EA82 use the same oil pump correct? I'm figuring it does because its just 1 1/2 EA82 engine blocks welded together Link to comment Share on other sites More sharing options...
Turbone Posted September 23, 2008 Share Posted September 23, 2008 Nope, its a different pump and gasket. Link to comment Share on other sites More sharing options...
idosubaru Posted September 23, 2008 Share Posted September 23, 2008 (edited) like rob said, they look similar but are not the same. the mickey mouse gaskets look identical, but when you put them side by side you see the actual differences.

torxxx Posted September 23, 2008 Author Share Posted September 23, 2008 ok that answers my question bout the pump question #2 who's got a source for a new or reman'd oil pumps for the XT6. I wanna get this thing going for ice racing this winter (snow is about 2 weeks away, which gives me bout 45 days before ice racing season starts) also head gaskets would be FTW too if someones got a source for those. the napa and car quest up here "claim" they cant get them anymore.

idosubaru Posted September 23, 2008 Share Posted September 23, 2008 xt6 oil pumps can be found online for around $150 i believe, been awhile since i looked but i had no problem finding them 3 or so years ago when i got a new one. resealing the oil pump is easy enough to do that it's worth trying to reseal it before replacing it. i can tell you for certain the ticking is coming from a compromised seal or a frozen HLA, not from the oil pump itself. although there's a chance a new pump will seal better and prevent future ticking in rare cases, i've never had to replace an XT6 oil pump to solve ticking problems myself (and i've owned 20+ XT6's) - so that's why i recommend it as a last resort. i'd diagnose the ticking as an HLA or not before doing anything to it if the engine still runs. in my experience HLA failure (sticking = ticking) goes up significantly in soobs driven with blown head gaskets. if that's the case i'd consider rebuilding yours (really annoying) or buying rebuilt ones - they're only $5-$7 each from mizpah engineering. which is well worth avoiding rebuilding yourself. it's easy but time consuming and tedious work. though worth doing once just to see. i have a pair of corteco XT6 head gaskets if you want to buy them PM me.

torxxx Posted September 23, 2008 Author Share Posted September 23, 2008 as far as the hlas go I've never had to replace one on any car I've worked on. That being EA82 engines. I've never torn into a xt6 so I dont know if they use the same hla. Another reason why I want to put a new oil pump in is because of low oil pressure Link to comment Share on other sites More sharing options...
Turbone Posted September 23, 2008 Share Posted September 23, 2008 The hla's are the same, as are most of the internals. Take the pump off and check it out. If theres scoring, grooves or discoloration, replace it. How many miles on the engine? Link to comment Share on other sites More sharing options...
idosubaru Posted September 23, 2008 Share Posted September 23, 2008 as far as the hlas go I've never had to replace one on any car I've worked on. That being EA82 engines. the XT6 HLA's are identical. i've seen them seized and cause tapping. Another reason why I want to put a new oil pump in is because of low oil pressurethat's normal and not caused by the pump itself. read the XT6 owners manual if it's still in the glove box, it even addresses that. the EA82/ER27 valve train needs volume, not pressure, so the pressure gauge is limited in some ways. a new pump might bring the "pressure reading" up a bit...but so would resealing your existing pump. for accurate oil pressure get an aftermarket pressure gauge and replace the sender.

torxxx Posted September 23, 2008 Author Share Posted September 23, 2008 yeah I've been wanting to find a aftermarket metric pressure sender for my lifted wagon too. lol been driving with out a gauge for over a year now. Problem getting them is where I live. Up here in the frigid north, the parts stores claim that subaru uses a metric thread instead of a pipe thread so tehy cant get me one. Figure I'd ask what the thread pitch is before I go screwing a aftermarket gauge into it Link to comment Share on other sites More sharing options...
