ystrdyisgone Posted May 1, 2014 Share Posted May 1, 2014 Just got my donor car for the ej swap! It leaks a fair amount of oil out of this though: Oil Pressure sensor? Quote Link to comment Share on other sites More sharing options...
Junkie Posted May 1, 2014 Share Posted May 1, 2014 I was also going to say oil pressure sensor, I have an EJ25D but it looks similar. Quote Link to comment Share on other sites More sharing options...
lmdew Posted May 1, 2014 Share Posted May 1, 2014 Yep that's the oil pressure sensor. Very easy to change, just screws in. Most of the leak is most likely the Power Steering pump. Major leak source on the Subaru engines. Quote Link to comment Share on other sites More sharing options...
heartless Posted May 1, 2014 Share Posted May 1, 2014 yes, oil pressure sensor/switch, and that is a common leak location. Just changed the one on my 95 - was pumping out nearly a quart in 50 miles! replacement can be had for between 10-15 bucks at any parts store Quote Link to comment Share on other sites More sharing options...
ystrdyisgone Posted May 1, 2014 Author Share Posted May 1, 2014 Imdew: Thanks! Are there o-rings or seals that can be replaced on the PS pump or does it require a whole new pump assembly? heartless: Thanks for the confirmation, is it advisable to put anything on the threads to help seal it up? 1 Quote Link to comment Share on other sites More sharing options...
heartless Posted May 1, 2014 Share Posted May 1, 2014 the new one should come with sealant already applied, simply take the old one out, put the new one in. very easy job. Quote Link to comment Share on other sites More sharing options...
lmdew Posted May 1, 2014 Share Posted May 1, 2014 Yes there is an oring on the bottom of the tank to pump connection. It's a Subaru part. If it's leaking there are rebuild kits for the complete pump. Search the USMB. Quote Link to comment Share on other sites More sharing options...

Search the USMB. +1...the subaru rebuild kits are awesome. cost ~$50 takes about 30 mins But the Oil pressure switch leak is common too....and arguably a more major issue.

ystrdyisgone Posted May 1, 2014 Author Share Posted May 1, 2014 Gloyale, could you explain what you mean about "a more major issue"? Like there's more to it than just the switch leak? Quote Link to comment Share on other sites More sharing options...
heartless Posted May 2, 2014 Share Posted May 2, 2014 the oil pressure switch leak is far more detrimental to the life of your Subaru than a power steering leak is. Like I said earlier - mine was pumping enough oil out to go thru a quart in under 50 miles - and this came about rather quickly, it wasnt a gradual increase.

ystrdyisgone Posted May 2, 2014 Author Share Posted May 2, 2014 Ohh I see. Yeah mine would visibly increase in oil leakage with increase of rpms. I replaced it today, 10 bucks. I'm not really seeing any signs of a PS leak. I'll be degreasing the engine tomorrow, and will be on the lookout for problem areas. Would anyone be so kind as to suggest common problem areas on these phase 1 ej22s? I'll be doing some research as well, but I'd like to get it running tip top as soon as possible. Note: There was very audible ticking of the lifters with the leaky Oil pressure switch installed, with the new one installed it purrs.

Fairtax4me Posted May 2, 2014 Share Posted May 2, 2014 Problem areas: (oil leaks) Cam plug o-ring on rear of passenger head Cam support o-ring on front of drivers head (same part number for both of these) Valve cover gaskets Oil fill tube o-ring Separator plate Rear access cover o-ring Camshaft and crankshaft seals Oil pump O-ring Oil pressure switch You got one down...

ystrdyisgone Posted May 2, 2014 Author Share Posted May 2, 2014 Damn, well thanks for the list fairtax, I've got some work cut out for me! I've heard about the separator plate.. is that only available from Subaru or can you get the steel plate and screws from other sources? Looks like I can just do all that when the engine is pulled out for the swap. Is there anything other than leaks I should look into while it's still running in the donor car?

Gloyale Posted May 2, 2014 Share Posted May 2, 2014 Gloyale, could you explain what you mean about "a more major issue"? Like there's more to it than just the switch leak? It's pressurized oil straigh out the gallery........They can go from bad to worse quickly......and you lose alot of oil and some pressure out to the end of the block. A few hundred miles and you can be low enough on oil to kill the engine.... By contrast, the Power steering leak only affects the power steering pump, not the engine.

Junkie Posted May 2, 2014 Share Posted May 2, 2014 In addition, as the thread starter said the valves quieted down when he stopped the leak. That indicates to me that the oil pressure was lower with the leak than without, which can certainly accelerate wear. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted May 2, 2014 Share Posted May 2, 2014 There is an aftermarket source for the separator plate now. I think Rockauto carries it? I'm not sure if anyone here has used one. I just spend the $35 for the dealer kit with the bolts. Bolts, the dealer will sell you special Allen head flange screws, but they use a very common metric thread. Either M5 or M6 I don't recall off the top of my head. You can get the right thread in about a 0.8-1.0cm length with a regular hex head. The top bolt that the arrow points to needs thread sealer.

heartless Posted May 2, 2014 Share Posted May 2, 2014 Oil separator plate - depends on what type you have on whether or not you need to actually buy a replacement Metal just needs to be resealed. Plastic ones definitely need to be replaced, along with new screws. The early cast alloy ones are the best if you can get your hands on one, but the later stamped steel ones work well, too. (it is not RockAuto that has the aftermarket one - it is PartsGeek.com) My 95 had a plastic one, I salvaged a cast alloy one (with screws) from a 91 block I had and it fit perfectly. The valve cover gaskets are a very common leak source - they are a rubber seal that gets hard with age/heat. Replacements can be had fairly cheaply from Rockauto.com. I got a set for my 95 for under $30, including both gaskets & new grommets for the bolts. Only accessable with motor & tranny separated: Oil separator plateRear access cover o-ring Should be addressed while doing a timing job: Camshaft and crankshaft sealsOil pump O-ring Cam support o-ring on front of drivers head Can be addressed at any time: Cam plug o-ring on rear of passenger headValve cover gaskets & grommetsOil fill tube o-ringOil pressure switch 1 Quote Link to comment Share on other sites More sharing options...

ystrdyisgone Posted May 22, 2014 Author Share Posted May 22, 2014 Cam support o-ring on front of drivers head Cam plug o-ring on rear of passenger head I'm getting my cart all ready to go on rockauto, but can't seem to find these ^^ things. Anyone know what else they are called? Quote Link to comment Share on other sites More sharing options...
ystrdyisgone Posted May 22, 2014 Author Share Posted May 22, 2014 Am I better off just getting a gasket set? Also, I've read mixed reviews on whether or not the head bolts are reusable. Anyone care to clarify for me? Quote Link to comment Share on other sites More sharing options...
upnorthguy Posted May 22, 2014 Share Posted May 22, 2014 Cam support o-ring on front of drivers head Cam plug o-ring on rear of passenger head I'm getting my cart all ready to go on rockauto, but can't seem to find these ^^ things. Anyone know what else they are called? On RockAuto I see those o-rings as part of a couple of the camshaft seal kits (cam seal and o-ring together) but I don't see the o-ring by itself. The Subaru p/n is 806946030 (seen here in the beergarage photos/repair info and described in this USMB thread). Quote Link to comment Share on other sites More sharing options...
