TheLoyale Posted March 2, 2012 Share Posted March 2, 2012 What is wrong with this motor? Nothing? Besides missing a few things. Mr. Adventure, how come you don't buy this motor? Vs the EJ18. Quote Link to comment Share on other sites More sharing options...

TheLoyale Posted March 2, 2012 Share Posted March 2, 2012 PM sent. Got the EJ18 anyway. (Just in case) Cool. If I remember right, you could take the heads from an EJ22 and stick then on the EJ18, for a High-compression EJ18 (Or some such thing) Useless information, but figured I would post it Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted March 3, 2012 Share Posted March 3, 2012 Pretty sure the 18 heads have smaller valves and the combustion chamber is the same size as the 22. So you get the same compression and less air flow. Something along those lines anyway. Quote Link to comment Share on other sites More sharing options...
Ricearu Posted March 3, 2012 Share Posted March 3, 2012 too bad your not down here in tx. i have a ej22 block with 205k on it. doesn't smoke, and ran dang good until I blew a HG on it, and never over heated it, just kept it full of water. It was in my 5 spd 90 lego. I dropped in a junkyard ej22 with 150k. I would give you that block for $50 and help you do the head swap for beer! I am thinking about tossing my left over ej25 heads on it for a boost in flow, and drop in compression ratio and turboing it... hmmm decisions decisions Quote Link to comment Share on other sites More sharing options...

AdventureSubaru Posted March 20, 2012 Author Share Posted March 20, 2012 Picked up the motor. Swapped out a bunch of parts. Swapped over the timing belt, water pump, fuel injectors, evap canister, air bypass valve, and any hoses that looked newer. Got everything installed. Looks pretty. Pics soon to come. But when I start the car it either A - sputters and dies. I can keep it going for a bit by giving some gas. Or B - Revs WAAAAY high. B is most common. I have to turn the car off about as quickly as it starts. I have checked and rechecked all vac lines and wiring. No leaks anywhere that I can see. Thoughts on what could be causing this?

mattocs Posted March 21, 2012 Share Posted March 21, 2012 Probably not your problem, but my Legacy was revving high the other day. I looked everything over...then I realized it was the cruise control cable stuck. Worth a look. Good luck. Quote Link to comment Share on other sites More sharing options...
AdventureSubaru Posted March 21, 2012 Author Share Posted March 21, 2012 Been researching and so far my best guess is the Idle Air Control Valve. When I swapped it over, I used RTV instead of a gasket. I'm thinking if some of it smushed into the valve and blocked the air passage, it will read low and possibly send the wrong signals - hence the revving. If not that, a few sites suggest that it could be something stuck in the throttle body. I'll check and see after work. Quote Link to comment Share on other sites More sharing options...
heartless Posted March 22, 2012 Share Posted March 22, 2012 glad to hear it at least fired off for you. yeah, i would be looking at the IAC valve too...also make sure the throttle cables are seated properly & not getting hung up. hopefully it is something simple and she will be purring like a kitten soon.

AdventureSubaru Posted April 21, 2012 Author Share Posted April 21, 2012 Waited long enough to post up pics. Now that she's moving, I've been posting less. here's a few snapshots of the process. Old Engine out. Carnage. (More pics of this to come. It's demolished in there. "New" engine going in seated. Had the worst headaches figuring out that I neglected to swap over the o-ring seals for the fuel injectors. I didn't even check to see if there was anything there to be swapped when i swapped the fuel rails over to the new engine. Car would redline right after starting. idles well now. Some more tune up stuff is in order in the not so distant future. But the car runs, drives and rides nice. Very cushy. Very clean. Very smooth.

heartless Posted April 21, 2012 Share Posted April 21, 2012 I am just glad that you did get it sorted out! I was starting to feel bad about the whole thing..LOL so what exactly happened with the original motor? I can see the hole in the top of the block, but - why?? what caused it?

Fairtax4me Posted April 22, 2012 Share Posted April 22, 2012 One of the rods decided it was time to bust out of the joint! You gonna split that block and take a few pics of the escapee and internal carnage? Quote Link to comment Share on other sites More sharing options...
AdventureSubaru Posted April 23, 2012 Author Share Posted April 23, 2012 That's the plan. Got almost everything useable off the old engine and will be posting up pics of the damaged on as I take the block apart. Surprisingly, it's not seized up entirely. The shaft still rotates 360.
