Corvid Posted September 12, 2013 Share Posted September 12, 2013 Through a series of unfortunate events, I ended up with this engine that was even worse than I thought when I made the deal. Known to me beforehand: 1994 EJ22 250K Trashed keyway / harmonic balancer / crank pully Valve cover leak Bad knock sensor But it turns out there's more... Upon further examination, the last 1/2 inch of the crank snout is turned down on one side from the woodruff key acting like a lathe bit. Bummer. After the engine was in my garage, on my table, I found out that the valve cover gasket leak was "treated" by adding Stop Leak to the oil. And that the engine was run for almost a 1000 miles on 15w40, to "slow leaking". (Even better, this was against my advice on the phone. Awesome.) So now I'm staring at this thing, trying to figure out how much damage I should expect inside. For those of you who have had a lot more time with these, should I... 1. Reseal the engine, replace the knock sensor, JB weld and file the woodruff keyway, ignore the worn down crank snout, replace the frontend and timing components and drop this thing in one of my EA wagons? Maybe run Seafoam in the oil for a weekend and then change the oil again? 2. Call it a loss, scrap the short block, practice rebuilding the heads, and store the rest as spare parts? 3. Scrap the short block, find a good EJ25D short block, and spend my winter gettin weird in the Frankenstein lab... 4. The obvious answer I haven't thought of yet...

johnceggleston Posted September 12, 2013 Share Posted September 12, 2013 www.car-part.com find an engine from an impreza, they are / may be a little cheaper, and start over. i hate to see one die, but for $300 you can get another one. Link to comment Share on other sites More sharing options...
Corvid Posted September 12, 2013 Author Share Posted September 12, 2013 (edited) I totally hear that. I don't exactly need the engine for anything at the moment, it was just leftover from a replacement. I guess I'm just trying to figure out what I should do with it, since its taking up space in my small garage. Am I hearing you right on thinking that the cranksnout and bearings are toast? Is there any reason the heads and intake would be shot as well? Edited September 12, 2013 by Corvid Link to comment Share on other sites More sharing options...
Rooster2 Posted September 12, 2013 Share Posted September 12, 2013 What stood out to me on your post is that the motor has 250K miles on it. I don't think I would want to spend much money on a high mile engine. I wouldn't think the thick oil with stop leak added would damage the engine. I have done similar with no problems with a '95, EJ22 engine I continue to run 3 years later. Yea, I think you can fix the snout without too much work. EJ22's are built bullet proof tough, and maybe some more miles left in this motor, suggest not throwing much money at it though. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 12, 2013 Share Posted September 12, 2013 (edited) life is too short to spend a 'lot' of time trying to create a working 250K mile engine from a bad one. Either quick-turn it and stick it into some non-critical project vehicle, or get a better 'base' to work with. my 2cents Edited September 12, 2013 by 1 Lucky Texan 1 Link to comment Share on other sites More sharing options...
johnceggleston Posted September 12, 2013 Share Posted September 12, 2013 if you have a need or a use for it, and you have a welder, just weld the sprocket , and the pulley?, onto the crank and call it a day. it will run until the crank seal dies.

Case closed, will someone please sell me an EJ25 shortblock for almost nothing? Link to comment Share on other sites More sharing options...
Fairtax4me Posted September 15, 2013 Share Posted September 15, 2013 Fill in the crank snout. Grab a junkyard sprocket and pulley and run it. Unless it was major overheated the bearings are fine. No need to Seafoam unless there is a bunch of buildup in the valve covers. If its just kinda dark all it needs is fresh oil. Link to comment Share on other sites More sharing options...
Gloyale Posted September 15, 2013 Share Posted September 15, 2013 (edited) Pull the oil pump off. Protect the openings and mating faces of the aluminum block with some fireproof welding mat or gloves, and then weld and grind the keyway fitting. you can even weld the key inplace if needed just make sure it's in the correct position and file it till the pulleys fit back over. TIG would be best but a good MIG machine (W/gas, or it's not really MIG) will do just fine. Reinstall the oil pump and and do a reseal maybe a t-belt and you've got a good engine again.

darsdoug Posted September 17, 2013 Share Posted September 17, 2013 I have a pulley and a knock sensor from a 94 Impreza EJ22 you can have for free if you are still thinking about fixing your EJ22? A couple of small imperfections as you can see, but still in working order. Link to comment Share on other sites More sharing options...
