Default 1992 subie needs a new heart

so if i cant find a reman'd ej22t what would be a good replacement long block. the local engine shop said they might be able to rebuild the old one. all i know is all 4 cylinders are reading 30 psi

No reason not to rebuild the EJ22T unless there is physical damage. If it's just 'wore out' at the end of a normal service life, the EJ22T can normally be rebuilt.

IMHO, Use a shop that is familiar with Subaru rebuilds or thye WILL make mistakes.

Must be faulty measurement, very unlikely all cylinders will read that low.

Get it rebuild with oversize pistons and rings, but as said above, only let an EXPERIENCED Subaru engine builder touch your engine.

Yes that is strange, something else going on. I would not decide a cure until I was sure what the problem was. IMO Good luck.

Hmmm. Don't give away your old block, that closed deck EJ22T is worth quite a bit nowadays. The big HP guys are desperate for the block halves. Worth 500-600 just for the casings!

**** yeah, you can't even buy those block castings from a dealer anymore (in the us anyways).
Have the block rebuilt.. It will be better than a new longblock! They have less tendencies to fail due to the closed deck design. Just.. When they are rebuilding it, make sure the block is honed with both case halves assembled, and a torque plate installed as well.. It is proven both here, and on other forums that honing a aluminum block without a tq plate oblongs the cylinder when you bolt down the cylinder head (which is necessary in order to operate) so.. Any machine shop who is building any aluminum block, especially a split case design block, without a tq plate is suffering from Intrarectalcranialitis!

well i would rebuild it but no machine shops around here will touch it. the company has 2 ej22t blocks that are rebuild able. closest machine shop that will do this block is quite a drive away. rather just have a reman block with warranty

south west colorado. closest shop that will work on it is a 8 hour drive one way. and thats just hone the block or if needed to bore the block. then i'd have to take to another shop to do the heads and assemble the block. or i can spend the money on a long block with warranty and do a couple upgrades that will assure a long life motor

Not sure if you can handle a wrench and spanner yourself, but if so... Remove the engine from your car and take the heads off yourself. On the SOHC engines that's really easy. The heads can be resurfaced and valve components reseated by any shop.

You could send the block itself out to a reputable builder. It's recommended to upgrade the connecting rods (or more specifically the rod bolts) to furtehr increased reliability of the engine (bearings). You may also want to install a new oil pump and water pump.

On a Subaru, these are very scary words. It's been my experiance that the best stock rebuilds are the ones that follow every rebuilding 'rule' with extreme attention to detail. Not the ones who 'tweak it'.

Subarus *need* to be bored and honed with the case halves bolted and torqued together and with torque plates installed in place of the heads. Most non-Subaru shops (even excellent ones) are simply not set up to do that.

There is also some expertise needed when assembling the case halves together the final time. (proper sealant, amount and placement, etc.)

The warrentee is good, but make sure they can, and will, stand behind it.

Warranty? Never know until they are tested. Was wondering if you are just going to driving it or are a race car driver? (you know beat the hell out of it)
