MTSuby Posted September 28, 2006 Share Posted September 28, 2006 Ok I'm sure this has been gone over, but if I'm going to replace the water pump, what are the things that I might as well replace while I'm in there? And any advice about tricks or special tools I'd really appreciate, plus sealants or whatever. Sorry everybody, it's leaking like crazy and I only have internet at work and I'm out of the office all week after 8am and can't find time to search archives!

Syonyk Posted September 28, 2006 Share Posted September 28, 2006 V-belts if they've got more than 30k or so on 'em, timing belts, and if your oil pressure is low, this would be a good time to replace your oil pump. -=Russ=- Link to comment Share on other sites More sharing options...
idosubaru Posted September 28, 2006 Share Posted September 28, 2006 Timing belt, crank seal, 2 cam seals (buy the cam seal kit from thepartsbin.com as it has the o-ring that goes behind each cam seal as well), and reseal your oil pump. the oil pump has an o-ring, a gasket and a seal. replace all three. thepartsbin has all three of those items as well.

Sweet82 Posted September 28, 2006 Share Posted September 28, 2006 I'll cast one vote for... If it's not broke...Don't fix it! Do the water pump and be happy. It's easy...at least on my EA81... My bolts were stiff and I broke one (Hint: always turn the right direction). Fix it and be gone... Link to comment Share on other sites More sharing options...
daeron Posted September 28, 2006 Share Posted September 28, 2006 (okay, im being humorous and not a jerk here) I'll cast one vote for... If it's not broke...Don't fix it! Do the water pump and be happy. It's easy...at least on my EA81... My bolts were stiff and I broke one (Hint: always turn the right direction). Fix it and be gone... Ill cast one vote for not having to tear the motor apart in six months to repair the oil leak/tensioner bearing/t-belt/cam carrier o ring/etc etc etc etc. there is about 2-4 hours of work involved in doing the water pump that is simply disassembly that would be needed to perform any of these other, routine high mileage maintenance items. (maybe less for someone who has done it three or four times, but realistically, first timer, 2-4 hours) when you do a tune-up, you dont install new plugs, pull the cap, replace the rotor, and use the same cap and wires, do you? not every time, anyhow. this job is at least fifteen or twenty times more intense than that (its not hard, but you ARE getting about up to your wrists in your engine, as opposed to dabbing your fingers with some oil) the standard mechanic's rule of thumb is: water pump, front crank seal, camshaft seals, timing belts. things like tensioners vary from vehicle to vehicle, but none of these parts are made to last forever. there are different seals on different engines that need to be re-done, but the golden rule is, once you take the front covers off, replace everything you can see down there. its a matter of spending an extra hour while you are already wrist-deep, or taking the time later to get wrist-deep again. my knowledge of the motor isnt encyclopedic enough yet for me to add any specific statement about what needs to be done.. go with the suggestions above. I just couldnt read that and look away:lol: and i truly meant no offense, Sweet82... but you kinda baited me into it. :-p it IS also the OHC ea82, with timing belts etc which IS a more complex motor than the pushrod ea81 youre talking about, so I will give you that. alot less to do when there are no timing belts or camshafts to seal so its not like we are even talking apples to apples here. in a way it wouldn't be fair to MTSuby to let the statement go unchecked, yanno?

idosubaru Posted September 28, 2006 Share Posted September 28, 2006 i don't know EA81's at all, but if they don't leak oil all that much then they certainly aren't anything like the EA82 platform. EA82's and ER27's don't hold back on the oil leaks. you would at least want to have the seals ready and if they look wet or leaky at all, then replace them. if they look fine, dry and no oil then sure thing, leave them (and don't forget to tell us how lucky you were to find them clean and dry). the crank seal can be a pain to get out and replace, particularly your first time. but the cam and oil pump only take a few minutes so it's a no brainer in the time and expense department for me.

GeneralDisorder Posted September 28, 2006 Share Posted September 28, 2006 Yeah - EA82 land is totally different. You can change the water pump in an EA81 in 15 minutes. EA82 is about 2 hours with the covers, and 1 hour without. GD Link to comment Share on other sites More sharing options...
MTSuby Posted September 29, 2006 Author Share Posted September 29, 2006 Great! Thanks a lot everybody. This'll be my first time tearing into a Subaru, I've always been a Toyota pickup guy, but recently downsized, and I'm finding there's a lot of similarities between my old '86 pickup and this wagon, except I don't fit so nicely underneath the car... But it sounds like this a job that's done from the top of the car, not the bottom. There's certainly some oil leaking, and I figure it's time to replace some stuff before winter and while I'm in there. Link to comment Share on other sites More sharing options...
idosubaru Posted September 29, 2006 Share Posted September 29, 2006 yep, all done from up top except maybe a couple timing cover bolts. once you get a look under the car you can pinpoint the oil leaks. leaks on the outside of the engine block, passengers or drivers side from the front of the engine are typically cam seals. centrally located oil leak will be oil pump or crank seal.

MTSuby Posted October 4, 2006 Author Share Posted October 4, 2006 Well, thanks for the advice everyone. I got the water pump, oil pump, and seals, as well as timing belts. I'm going to dig into it this weekend. Link to comment Share on other sites More sharing options...
