Subaru_dude Posted July 23, 2008 Share Posted July 23, 2008 Couldn't believe a search didn't turn anything up on this. So I have a '91 Legacy EJ22 but when I got it from the yard the intake was pulled off of it and the bolts were missing. So I go back when there's more Legacys and find one with the intake and steal the bolts (can't remember what year, but it was a first gen Legacy... '94 at the newst). I got some new gaskets and put the intake on today, but the longer bolts are too long for some reason. I was sure to swap the long and short bolts around to see if that would work but it didn't. I have the shorter ones on the inside and the longer ones on the outside. Why would they be longer? Isn't it exactly the same engine? I thought they stayed exactly the same up until '97 when solid lifters were introduced. How long do the bolts need to be? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted July 23, 2008 Share Posted July 23, 2008 are you sure all of these were early legacy's? maybe a 1995 intake manifold is different...there were a few changes then? Quote Link to comment Share on other sites More sharing options...

Yep the first bodystyle, kinda squarish. Does anybody have pictures of the bolts? I'll go downstairs later and take some pics of them in the holes in a few.

idosubaru Posted July 23, 2008 Share Posted July 23, 2008 you shaved the heads didn't you - the wrong side! just kidding. if they're too long you can cut them down, i've done that before. cut it to size and chase the end with a die. that'll be an 8 x 1.25 thread pitch on the intake bolts. being a junk yard - is it possible those bolts were removed and someone just put something else in there, the wrong ones? or they were the right ones?

Subaru_dude Posted July 23, 2008 Author Share Posted July 23, 2008 The ones that I removed to replace the ones I lost were flush with the intake like they should be. This is really baffling me... I'm considering taking them with me when I go back and putting them in the same car to make sure they fit. This really doesn't make much sense. :-\ I'm positive they came out of an EJ22 first gen Legacy. I don't think trimming them down would work because the threaded area is about 1 1/8" long and that's about how deep the hole is. If I trim any off then the smooth part of the bolt would have to mash the threads in the head to sink all the way into the hole. I'm gonna go have another look and make absolutely sure I have a problem. Quote Link to comment Share on other sites More sharing options...
Subaru_dude Posted July 24, 2008 Author Share Posted July 24, 2008 I am so confused now. I'm thinking maybe it's just the intake... because not only do the bolts not fit right, but this thing doesn't even fit in the hole right (can't remember what it's called). I seem to remember the engine being completely untouched witn I pulled it, I must be completely wrong or losing my mind. Is there any special way to get this in? http://i136.photobucket.com/albums/q200/SMASHmySOOByDONTya/EJ22%20conversion/DSC_0238.jpg The bolt sticks out about 1 1/8". Gonna have my dad make some kind of spacer for it at work. Does anybody have a pic of this area on their EJ22? I want to see if the hole is raised here. http://i136.photobucket.com/albums/q200/SMASHmySOOByDONTya/EJ22%20conversion/DSC_0237.jpg Please help me... lol.

idosubaru Posted July 24, 2008 Share Posted July 24, 2008 something isn't right. that's a knock sensor in the first picture. something is not compatible there. you have the hole covered up - is the hole there? it's just too small or not there at all? as for the bolts, i have no idea. the older generation intakes had an upper and lower intake manifold. the lower manifold was really short and you would hardly ever remove it, you would typically just remove the entire thing as an assembly with the upper/lower attached together. if this was an older gen subaru i would think you removed the upper intake manifold and so the bolts are too long because they don't have to pass through the lower manifold. but that sounds like hogwash because i don't think any EJ's have an upper/lower manifold - they're all one piece. given the bolt issue and the knock sensor...it seems to me one of your parts is from another engine. it wasn't a turbo Legacy was it?

johnceggleston Posted July 24, 2008 Share Posted July 24, 2008 what are the chances the engine is a 1.8L or similar?? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted July 24, 2008 Share Posted July 24, 2008 what are the chances the engine is a 1.8L or similar??i asked about that:are you sure all of these were early legacy's? and he seems confident it's all early gen legacy stuff, but i'm still wondering too.

Gloyale Posted July 24, 2008 Share Posted July 24, 2008 Yep the first bodystyle, kinda squarish. Hmm, in my mind, none of the Legacies are *squarish* It isn't possible you got the bolts from a Loyale or GL is it? Quote Link to comment Share on other sites More sharing options...
Subaru_dude Posted July 24, 2008 Author Share Posted July 24, 2008 Hmm, in my mind, none of the Legacies are *squarish* It isn't possible you got the bolts from a Loyale or GL is it? No it's definitely a Legacy. I know my EAs from my EJs. And the knock sensor just doesn't fit... but I found my recipt when I bought the engine and it says it was a complete engine so it apparently came with the intake and I seem to remember removing the knock sensor and intake to wrap a chain around the block because I didn't realize their were hoist points. I'm going to take it with me to the j/y and see if there are any differences in intake/knock sensors. This is baffling me BIG TIME. Here's an attached pic of the gen of Legacy I pulled the motor and intake bolts out of. http://pipstore.com/info/wp-content/uploads/2008/04/subaru_legacy_1st_generation.jpg And I don't think it was a turbo, but I can't say anything for sure at this point lol.

aircraft engineer Posted July 24, 2008 Share Posted July 24, 2008 If you go the spacer route put it under the sensor. The brass ring is where the sensor "grounds" to the block and why the CEL comes on when you pull the sensor "out". I'm pretty sure that a 50k-ohm resistor in the circuit grounded to the engine will run the car without the CEL (but you won't have a knock sensor either) Quote Link to comment Share on other sites More sharing options...
Subaru_dude Posted July 24, 2008 Author Share Posted July 24, 2008 Ok went to the JY. Found that ALL the first gen Legacies had 2 short and 2 long bolts on each side. The inner ones were the longer ones because the bottom "deck" (for lack of a better word) was raised about an inch. My intake does not show any signs that it was ever designed like this. HOWEVER, there was a '95 Legacy there and all 8 intake bolts were the same length, the shorter ones. So it appears my intake was from a newer model, OBDII maybe? It still only has the 2 plugs for the ECU so I'm not too concerned about that. That still doesn't explain why I had an extra fat knock sensor, not even the '95 at the yard had that, nor did any of the other first gen Legacies. Does anybody know why there would be such a variation? Quote Link to comment Share on other sites More sharing options...
aircraft engineer Posted July 24, 2008 Share Posted July 24, 2008 not OEM Sub? maybe? Quote Link to comment Share on other sites More sharing options...

I just had to say it as a remote possibility. Hope no offense was taken. Now on to this. http://i136.photobucket.com/albums/q200/SMASHmySOOByDONTya/EJ22%20conversion/DSC_0238.jpg What you are calling a Knock sensor is actually the Crank angle sensor. You can clearly see the timing marks on the belt cover, front of motor. The knock sensor is in the back and somewhat *under* the intake. at any rate, the newer motor may have a different size hole than you're original. Did you get the Sensor with the new motor? If so you should be able to just swap connectors. Quote Link to comment Share on other sites More sharing options...

Nope no offense taken. I had a feeling it wasn't the knock sensor... grossgary said that's what it was, maybe he didn't realize what the pic was actually of. The replacement was from a '92 Legacy but there was also a '95 at the yard but it STILL didn't fit the '95 nor did it really look like it (the '95 had a plug directly on the sensor itself that the wire plugged into). But whatever, I now have the one I need. Still baffling though... it does indeed seem that somehow my intake got swapped at some point (have no idea how in the hell that happened). I think I'll do some research on that and see what I come up with... Quote Link to comment Share on other sites More sharing options...

Actually, it is the crank sensor. The knock sensor is below tin intake maniford to the rear of the engine. It looks like the right sensor for the engine being worked on too. . . Is there corrosion or somesuch on the inside of the hole that barrel goes into? Quote Link to comment Share on other sites More sharing options...
