***********Reassembly of block.... semi quoted from book...

Carefully lower the right crancse section into position on the left crankcase and install the rightside bolts (the two long 12point, the two short point, and the 7(?) other bolts.. Tighten them to aproxx 14-22 ftlbs. Turn over and install the 6 12point bolts, tighten to 20 ft lbs. go back to the other side and retorque all bolts to 22 ftlbs. Then torque the 4 12point bolts to 37lbs. flip back over and tight the 6 12-point bolts to 37 lbs. then install the 10mm bolt inside and the 12mm bolt on the back where the flywheel mounts. I just hand tighten these with a open ended wrench.

Make sure to get the 4 o-rings in place (3 black and 1 orange), and use Fujibond sealant.

Cylinder head sequence. this is what I do.

Going in a diagonal motion,
tighten to 22 ftlbs.
Tighten to 51 lbs
Loosen all bolts 180 degrees
Loosen all bolts 180 degrees (yes, you do this twice)
Tighten middle bolts to 27 lbs.
Tighten outer 4 bolts to 170 in-lbs !!!!!!!!! Thats about 14 ft lbs.
tighten all bolts 90 degrees
tighten all bolts 90 degrees (yes you do this twice.

Done.

Lube both faces of the head bolt washers
I personally replace the "tighten all bolts 90 degrees (yes you do this twice." step of head bolts to "tighten all bolts 90 degrees or 80 foot pounds, whichever is more" to prevent future leaks.

Put oil on the washers or the torque readings will be inaccurate.

The last step of tightening should be at least 80 foot pounds. Usually this is more than 90 degrees. A big reason the DOHC 2.5 leaks is from a crappy torque sequence and inaccurate torque wrenches. The low torque specs before the 90 degree turns have a HUGE effect on final torque.

edit: Here is the specs from the 92 turbo service manual (which match yours) with my modified last step

middle top bolt is #1, middle bottom is #2, front upper is #3, front lower is #5, rear upper is #6, rear lower is #4
lube all washers with engine oil
tighten all bolts to 22ftlb
tighten all to 51ftlb
back off all by 180
back off all by another 180
tighten 1 and 2 to 27
tighten rest to 14 in order of 3 4 5 6
tighten all by 90 degrees in numerical sequence 123456
tighten again to 80ftlbs or 90 degrees WHICHEVER IS MORE


I have tightened head bolts by 360 degrees by mistake which you shouldn't do but nothing bad happened.

you said "tighten all by 90 in numerical sequence 123456"

do you mean 90 foot lbs or degrees?

I'd assume he has better mechanical aptitude than you. Asking a question when you don't know the answer shows more intelligence that pretending to know it all.

Wink progress

I have ordered a FSM from ebay, the seller decided to ship it media mail could take up to 2-3 weeks before i see it from what im told darn usps.

But i need to get my ej22t reassembled, so i need to find out the torque specs for the ROD bearings. I am using all new ACL race bearings, Should I plastic gauge these and if so what is the thickness / spec the last thing i wanta do is spin a rod or main bearing?

Should I use subaru black sealant on both the block halfs and or should i use subaru greay sealant, should i use some to hold the main bearings in place?

Or better yet has anyone created a rebiuld video!!

I would use plastigauge. Dont worry about buying specific subaru sealant. I use Ultra Grey (3m or threebond I think, get it @ Joes). Never use sealant for the bearings/ rod caps. Make sure to get an assembly lube of some sort. I reccommend Lucas Oil Oil additive, sticky as hell and works well.
