jp71ss Posted February 26, 2013 Share Posted February 26, 2013 I cleaned it and got it bored, putting the last piston in and I find a crack! I don't know if it was cracked before it was bored but it is definitely cracked now! Anybody ever sleeve a EJ25 block? Link to comment Share on other sites More sharing options...
jp71ss Posted February 26, 2013 Author Share Posted February 26, 2013 I just realized that this is the same cylinder that had no compression. Duh! Well I didn't see the crack before. I guess I will have to get it sleeved now. Back to the drawing board. Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 26, 2013 Share Posted February 26, 2013 Are you aware of the cost associated with sleeving a block properly? It'd cost you less to buy a new 257 shortblock.

jp71ss Posted February 26, 2013 Author Share Posted February 26, 2013 We don't have any shops close by that can magnaflux. We are out in the stix! Enlighten me on the cost of sleeving this block and the cost of a new shortblock. What would the compression be on a new ej257 shortblock? Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 26, 2013 Share Posted February 26, 2013 What car is this for? I assume you are going for big power with a sleeved build? Typical sleeve installs are ~$3000+ if done correctly.

spooln30 Posted February 26, 2013 Share Posted February 26, 2013 I don't understand why anyone who is in the process of rebuilding an engine and already had the block at a machine shop wouldn't take the extra step to see if there are any cracks. Knowing you had low to no compression in one cylinder it's a must. Everybody makes mistakes some just cost more then others. Far as sleeping the block its not worth it, the cost isn't cheap and the blocks are easily available. GL. Link to comment Share on other sites More sharing options...

jp71ss Posted February 26, 2013 Author Share Posted February 26, 2013 We didn't see any cracks and the shops around here don't have magnaflux capabilities. We are not a big city with unlimited resources. I found the crack after I finished cleaning it. Hindsight is 20/20 and I understand what you say but it didn't show up till after the bore and final cleaning. If we had the shops here that we used to have before everything went away I could have gotten it magnafluxed. A waste to sleeve one cylinder in a block? Since it is not a high horsepower build I will find out the cost today and see if it is worth it. If not I might sell the whole project. Will a 251 or 253 be a direct bolt up with sensors and everything? Thanks for the thoughts. Link to comment Share on other sites More sharing options...

But if you could, it is unlikely your town has anyone capable of correctly installing a dry sleeve. It would turn you current $200 error into a several thousand dollar one.

No, it won't be compatible but I reckon that would be the only way to obtain a 251-253 block, which will be. All you would have to do is swap your heads, sensors, & crankshaft gear/sprocket over, start up, & keep it moving. For the 251-253-257, the thrust bearings are on #5 instead of #3. If it has a 5th digit letter, it's Phase 1 & Phase 2 engines have 5th digit numbers. For example, EJ25D is phase 1 while EJ251 is phase 2. Link to comment Share on other sites More sharing options...
subikid90 Posted February 26, 2013 Share Posted February 26, 2013 The short block from a 251 or 253 will be a direct swap with your stock heads/intake manifold/sensors from the car. It will even bump up your compression. Use 06 sti head gaskets. -Subikid90 1997 Legacy GT 5spd & EJ251 w/EJ25D heads ~10.5CR 1998 Legacy GT Limited waiting for EJ22T hybrid swap Link to comment Share on other sites More sharing options...

Well since I called a shop about an hour away and they said they could sleeve one cylinder for about $125 to $150. So I guess I will take it up there and see. I don't quite understand why you couldn't sleeve one cylinder since it has sleeves in it anyway. Doesn't make sense. Link to comment Share on other sites More sharing options...

Our "sleeves" have iron liners in them. Will the sleeve be exactly the same as the others? Also, the new sleeve would have to be bored & honed to the same exact size as the others & even then, all of the sleeves would need to be honed & bored together.

johnegg Posted February 26, 2013 Share Posted February 26, 2013 i have a short block if you are interested, out of a 98 outback manual trans. the crank has ''end play''. but your crank and new bearings would correct that. i don't remember the miles off hand but they were low enough for me to save the block. maybe swap seats at the same time.

Terry Walters said he could fix mine but I will know more Thursday afternoon. I don't have all the seats out of the outback yet. Might need help getting one out cause pass rear door won't open. You may want to look at them first. I have the whole car too. Maybe we can discuss it Thursday. PM me your number so I can call you if Terry can't fix it.

johnegg Posted February 27, 2013 Share Posted February 27, 2013 Is a 99 outback 2.5 a #5 thrust bearing location block? no it's a 98, #3 thrust location i think. i'll see if i can find the mileage info. the rear seat bottom is held in by 2 bolts. on the floor in front of the seat, covered by carpet? and part of the hinge. the rear seat backs are held in by 3 bolts under the seat bottom (and maybe 3 bolts on the back side). the backs may separate during the removal, not a big deal. the passenger door will make it more of a pain but should not prevent the removal.

snederhiser Posted February 27, 2013 Share Posted February 27, 2013 Hello; Before you waste moe money, moe money, get another block! First thing, magnafluxing the block does not work on a aluminum! Leak detection is done by blacklight and dyes. A dry sleeve works only on a cylinder that is not leaking antifreeze. Welding will distort the block. I do motorcycle and automotive machining as a service, Steven. Link to comment Share on other sites More sharing options...

I do motorcycle and automotive machining as a service, Steven. It wasn't leaking antifreeze, just didn't have compression. The crack is not in the aluminum, not that I can see. If it is determined to not use this block I will talk to Johnegg about his. I already have a price locally for a 99 model but unsure if it is a # 3 or # 5 thrust position. If it isn't too wet Thursday I will try to get the seats out. Link to comment Share on other sites More sharing options...
DOHCEJ22E1 Posted February 27, 2013 Share Posted February 27, 2013 98 25D is #3 & 99 25D is #5 in thrust bearing locations. 99 is actually a phase 2 block. Link to comment Share on other sites More sharing options...
