mattyyg Posted July 15, 2012 Share Posted July 15, 2012 Just got done putting my engine back in to a 95 Impreza 2.2. When I had it out I replaced all the oil seals, valve guides, head gaskets, intake and exhaust gaskets, timing belt, water pump and any other piece of rubber that was rock hard. The first start (after sitting on a stand for 3 months) surprisingly started like it was just run yesterday. Idle is smooth, no misfire, no smoke, except the valves are loud as hell. Sounds like all of them are just getting a beat down. We recently had a bit of a heat wave here in the midwest so I didn't work on it for a while, just too hot in the garage. During that time the heads where sitting on my work bench, mating surface down. I've read (now) this is a bad idea and this drains the oil from the HLA's? I've also read somewhere that you can let the thing run for about 1 hour to get oil back in there? Can anyone confirm if this is true? The engine sounds terrible and I don't want to damage it, but I'd also like to avoid pulling it again as I've just put it back in. Link to comment Share on other sites More sharing options...
jarl Posted July 15, 2012 Share Posted July 15, 2012 The EJ22 I bought for my OBW sat somewhere for 6 years. Letting it run for a while quieted the valves completely. Don't get me wrong... I would have preferred to service the HLAs and purge them before closing everything up, but letting it run like that didn't have ill effects that I can tell.

johnceggleston Posted July 16, 2012 Share Posted July 16, 2012 ASSUMING the replacement engine is a 95 as well, let it run. it will take a little while for the HLAs to pump up. not to worry. it will quite down. they are great engines. Link to comment Share on other sites More sharing options...
idosubaru Posted July 16, 2012 Share Posted July 16, 2012 if it's just HLA's needing pumped up - run it. very common with all the EA/ER engines that have HLA's too. sounds like death noise for 10 minutes or so, really bad....shouldn't take an hour, 15 minutes or less in my experience.

mattyyg Posted July 16, 2012 Author Share Posted July 16, 2012 Grabbed a couple coronas, started it up, and let it run for about an hour last night. It has calmed quite a bit, still not perfect, I think a couple of them still need some time. Definately a 95 engine. I don't think it was well taken care of before me, it had 145k on the original plugs, wires, and timing belt. Definately a strong engine though. Thanks for the feedback!

idosubaru Posted July 16, 2012 Share Posted July 16, 2012 running instead of just idling it may help. it has fresh oil in it right? shouldn't much matter but what weight? Link to comment Share on other sites More sharing options...
mattyyg Posted July 16, 2012 Author Share Posted July 16, 2012 running instead of just idling it may help. it has fresh oil in it right? shouldn't much matter but what weight? Yes, I put fresh oil it, but didn't change the filter yet. The filter only had about 300 miles on it before I pulled the engine. Maybe I shlould just swap that out too since it's only a couple bucks. I've been using 5-30 year round. Link to comment Share on other sites More sharing options...
idosubaru Posted July 16, 2012 Share Posted July 16, 2012 sounds like you're good to me. hopefully they just free up. in the older motors it doesn't hurt anything that they make noise...it's just really annoying, i would assume the same here though i've never really done any HLA work in EJ's, i've just swapped heads without paying much attention to them. haven't ran across any that make noise yet.

davebugs Posted July 16, 2012 Share Posted July 16, 2012 MMO and a "spirited" drive has always worked for me. I'd do this before changing filter. I usually take a 15 minute drive and all is fine. Change oil & filter afterwards. Link to comment Share on other sites More sharing options...

davebugs Posted July 17, 2012 Share Posted July 17, 2012 Marvel Mystery Oil. Never used it until I saw folks here saying it works on Subaru's - and it does. Link to comment Share on other sites More sharing options...
