Monte Posted May 26, 2006 Share Posted May 26, 2006 Hi, been posting on the Older Gen board, have a '97 OBW that needs a HG change. What's the "job list" for this? I'm pulling the engine, so might as well get it all done while it's out. Auto trans if it matters, and 93k. From what I've gathered, I should do: HG's cam seals rear crank seal timing belt oil pump o-ring? part of oh gasket set? oil separater plate? part of oh gasket set? edit: water pump edit: check all tensioner bearings Parts needed are: Overhaul gasket set Valve cover gaskets (not included in OH kit) Spark plug gaskets (not included in OH kit) timing belt autotrans fluid oil separater plate edit: water pump More could be done, but what's really necessary at 93K?

2X2KOB Posted May 26, 2006 Share Posted May 26, 2006 I'd do the water pump, might save you going back in there next year. And of course the crank front seal, and check all the spinning bits on the front of the engine for bearing problems. Can't you get a gasket set for the head job only? Or do you have to buy a full engine overhaul set? Quote Link to comment Share on other sites More sharing options...

Or do you have to buy a full engine overhaul set? I was going by Skip's parts list here, he stated it was less expensive to get the OH kit instead of buying the pieces. If I do a water pump, oil pump o-ring, cam seals, crank seals, etc., he's probably right. If I was just doing the HG I'd just get those gaskets.

2X2KOB Posted May 26, 2006 Share Posted May 26, 2006 Are you going to send the heads out to a machine shop for minimal shaving, crack checking, and valve job? This might add a couple hundred bucks, just guessing. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted May 26, 2006 Share Posted May 26, 2006 do the water pump if you're doing the timing belts. belts are good for 100,000 miles so you won't be going back in there anytime soon. otherwise you're relying on the stock water pump to go 200,000 before you get to the next timing belt/water pump install. do it all now and hopefully you're good for the next 100,000 miles. check all the timing belt pulleys, replace any that are loose or noisey for the same reason....if the water pump or the bearings fail they take the timing belt with it and this is an interference engine.

Good call, I hadn't looked at the water pump in that way. 200k does sound like a lot of miles for a water pump. Monte Quote Link to comment Share on other sites More sharing options...
2X2KOB Posted May 26, 2006 Share Posted May 26, 2006 Stupid question time: When you pull the engine, does the transmission stay in the car? How about the torque convertor - does it stay on the trans, or the engine when the two are split? (It's been a long time since I've done anything like this and never on a Subaru) /kthanks Quote Link to comment Share on other sites More sharing options...

My auto trans experience is with a Ford, the torque convertor stayed with the engine, I'm thinking the Subaru is the same. Not sure there's a way to detach the TC from the engine before pulling the engine, though I hope I can. Monte Quote Link to comment Share on other sites More sharing options...
