WoodsWagon Posted March 7, 2011 Share Posted March 7, 2011 Well your first problem is that you're trying to replace a phase 2 Single Overhead Cam (SOHC) 2.5l with a Phase 1 EJ22, so the bellhousing bolt pattern is different and the wiring/sensors/injectors are different. The EJ22 swap is for 96-99 EJ25d's which is the Dual Overhead cam (DOHC) 2.5l. These are the ones that blow the headgaskets internally and have a lot of problems. SOHC EJ25's blow the headgaskets externally, so coolant leaks out of the engine onto the ground, and this can often be fixed with a bottle of stop leak. Subaru sells it as "coolant conditioner" in small blue bottles. What's broken with your engine? It may be easier to fix it than swap the EJ22 you got into it.

3Pin Posted March 7, 2011 Share Posted March 7, 2011 Ditto on the last comment. I have a friend in MIlwaukee who has a good 2.5 of your era. Another friend of mine is looking to fix a 98 forester stick with a bad 2.5. It might a better match all around. How do you want for your 96 motor? I think the only other issue you might have is the EGR. Auto's have em, stick's don't. Quote Link to comment Share on other sites More sharing options...
72 Fargo PW Posted March 8, 2011 Author Share Posted March 8, 2011 ok i was told the ej22 was a phase 2...my engine hgas a broken wristpin so unknown damage internally Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted March 8, 2011 Share Posted March 8, 2011 my engine hgas a broken wristpin so unknown damage internally i bought a 97 obw with a ''bad wrist pin'' for cheap. (i already had the ej22 engine and i was looking for a way to use it.) turns out it was piston slap. i drove the car for 40k miles and with no engine work and just recently sold it. what's your engine doing? who told you it was a ''broken wrist pin""? have you taken it to a ''subaru'' mechanic.? your situation is probably not the same as mine, but non-subaru mechanics mis-diagnose things all the time. i don't even know if '00 have piston slap.

hankosolder2 Posted March 8, 2011 Share Posted March 8, 2011 ok i was told the ej22 was a phase 2...my engine hgas a broken wristpin so unknown damage internally An engine from a '96 should not be a phase II if it's an EJ22. If memory serves the phase II ej22s have the spark plug access through the valve covers, whereas the Phase I engine have the spark plugs angling out of the top of the heads. If it's a phase I it's not a good match for your vehicle. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted March 8, 2011 Share Posted March 8, 2011 cars get misdiagnosed would be a good idea to verify what the problem is. although knocking isn't unheard of for EJ25's, piston slap, timing tensioners, and cracked flexplates have been mistaken for engine failures before. 96 EJ22 won't plug and play into a 2000. there's no easy way around the snags to that. you can swap anything you want - if you swap the entire engine harness, ECU, and splice things in to make it work. most folks aren't looking for that level of work so you'll have to let us know what you're trying to do.

72 Fargo PW Posted March 9, 2011 Author Share Posted March 9, 2011 thanks guys..im a newbie to subaru and am learning ...ok the 96 ej 22 wont work in my 2000 outback so ill pull the 2.5 and tear it down to see whats wrong. i already have an add in the local classifieds for 2000-2004 ej 25 out of an outback or a baja...i heard the forester and impreza motors wont work./ anyway ill let ya know if it was wristpin or not. anyone want a low k ej 22 1996? cheap Quote Link to comment Share on other sites More sharing options...
davebugs Posted March 9, 2011 Share Posted March 9, 2011 i already have an add in the local classifieds for 2000-2004 ej 25 out of an outback or a baja...i heard the forester and impreza motors wont work cheap FYI the JY's used to tell you that a 95-99 2.2 from an Impreza wouldn't work in a Legacy - and they were wrong. Funny thing is the Impreze 2.2 was 100 bucks cheaper than a Legacy 2.2 delivered to my door with 6 month warranty. Basically 250 vs. 350. The 2 JY's I bought the most from eventually caught on - I'd always ask for a 2.2 Impreza engine first and if none then I asked for a Legacy. Mind you these were typically to be swapped inplace of a 2.5. But perhaps someone who knows here will tell you if it must be a Lecacy or Baja and why an Impreze or Forester engine won't work if they are easier or cheaper to find.

WoodsWagon Posted March 10, 2011 Share Posted March 10, 2011 It's not a broken wrist pin, I can tell you that. Rods or pistons go before wristpins do. Before you pull the engine and tear it down, tell us exactly what it's doing or not doing, and we'll do a much better job diagnosing it than the shop you took it to. It may be something simple and straightforward to fix, or not a problem at all. Quote Link to comment Share on other sites More sharing options...

Rooster2 Posted March 10, 2011 Share Posted March 10, 2011 broken timing belt? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 10, 2011 Share Posted March 10, 2011 Any EJ251/EJ253 will work. That's all '99 to '04 Forester/2.5RS engines, and 2000 to 2004 (or was it 2005?) Legacy, Outback, and Baja engines. Just use your existing manifold to insure complete compatibility of the wireing, etc. GD Quote Link to comment Share on other sites More sharing options...
72 Fargo PW Posted March 10, 2011 Author Share Posted March 10, 2011 Sounds like a timing belt to me took the timing belt inspection cover off looks fine and turns when engine turns over Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted March 11, 2011 Share Posted March 11, 2011 took the timing belt inspection cover off looks fine and turns when engine turns over Check timing belt lay out for bad tensioner or pulley, even though the belt turns when the engine turns over. Like cj7135, this sounds like timing or bad valves related. Quote Link to comment Share on other sites More sharing options...

72 Fargo PW Posted March 12, 2011 Author Share Posted March 12, 2011 ok so just removing insp. cover is not enought then. ill need to remove the rad and all the timing cover to see if they are worn or broken ? Quote Link to comment Share on other sites More sharing options...
72 Fargo PW Posted March 13, 2011 Author Share Posted March 13, 2011 You need to remove the timing covers and rotate the engine by the crank shaft with a socket until all your timing marks line up. If they don't, then that's your problem. To check the tensioner, just push down on the belt from the top on the right-hand side with your thumb, and any excessive play means the tensioner has failed. There's a 99% chance you'll have to remove the engine. sorry that last part about removing the engine could you elaborate Quote Link to comment Share on other sites More sharing options...
72 Fargo PW Posted March 13, 2011 Author Share Posted March 13, 2011 ok im just heading out to do the teardown...off hand does the harmonic balance have to be removed to get al the timing covers off? thanks in advance so i can rent a puller .

idosubaru Posted March 13, 2011 Share Posted March 13, 2011 (edited) i've always removed them without any special tools. about 5 out of a butt load have been a real pain and i wish i had used a tool. technically you could remove the timing covers without removing the crank pulley....but you have to break them to do it.

72 Fargo PW Posted March 13, 2011 Author Share Posted March 13, 2011 ok guys i have a 3/4" impact gun on the harmonic balancer bolt and it wont move.is it reverse thread??? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted March 14, 2011 Share Posted March 14, 2011 ok guys i have a 3/4" impact gun on the harmonic balancer bolt and it wont move.is it reverse thread???no, it's just a standard thread. they can be a workhorse to budge. socket and 3 or 5 feet of pipe is what you need or a gun with more torque. be sure you have the engine pinned so it can't rotate while you're hammering or loosening it. keep in mind to tighten it really good when you reinstall too as they will back off and tend to cause a lot of damage if they do.

72 Fargo PW Posted March 14, 2011 Author Share Posted March 14, 2011 Ok today all timing marks line up , belt looks good no slack , all tensioners look good. so now what check crank and cam sensors?. the noise i first heard im assuming is bottom end damage Quote Link to comment Share on other sites More sharing options...
