August 27, 200520 yr Hello all, Had a little meet with oddcomp today and we looked over my engine. We agreed that perhaps only the rod bearings are hosed and that the power loss in the engine is the knock sensor retarding the timing...... So im asking you gurus who tear into engines...is this theory plausible?? and if i unbolt the Oilpan, will i be able to get to the bearings and rods?? THanks for the help Cory For more info check out the initail post http://www.ultimatesubaru.org/forum/showthread.php?t=41825

So im asking you gurus who tear into engines...is this theory plausible?? and if i unbolt the Oilpan, will i be able to get to the bearings and rods?? It's definately plausible, the knock sensor signal can prod the ECU to yank 10 or more degrees of timing. That's gonna knock the wind out of the midrange torque and give you molasses-like throttle response. Have you done a compression check? Also what is the cause of the screech noise? I'm not certain about refreshing the bottom-end ...from the bottom-end.
August 27, 200520 yr Author Well the screeching noise was only present for about 2 minutes when we first started the engine...now it just has a nasty rod knock...it idles fine but the midrange is gone...... Any other confirmations

THanks for the help Cory For more info check out the initail post http://www.ultimatesubaru.org/forum/showthread.php?t=41825 I've had a couple of EJ22s apart before and there's just no room to get a wrench onto the rod cap bolts; let alone a torque wrench when it time to reassemble. I know the shop I use to work at has a few used EJ22 longblocks on the shelf, maybe a shortblock too. The name of the place it Mt. Tech, their number is 503-650-3686, and their open Tuesday to Saturday 8 to 5
August 27, 200520 yr eh i was not totally sure i figured since it was a bigger motor there might have been room to do it
