OK, 230K miles in and have developed a rod knock on #1 (low oil level gone unnoticed, but no light came on), but is only noticeable at start up and under half throttle. Redone heads last year, timing belt, water pump, radiator etc, etc, etc. Need to replace the Cats to pass smog and wanted to know if I should rebuild what I have with a ring and bearing swap or go junkyard short block.
Either way, where is the best place to get a gasket set, seems to be several options out there.
I'm going to sell it when finished, but want to pass on a decent product, not slapped together just to sell, I'm not that kind of person.
Thanks for the help!

If your car is a 2000 then the following holds true. You mention DOHC...that wasn't available in 2000. This is where it's helpful to clearly state year and model.

Any 2000 - 2004 EJ25's
1999 Impreza RS or Forester

1999+ EJ22 will also be bolt in and plug and play but you'll need the exhaust manifold with it.


(If it is DOHC then it's just every EJ25 not mentioned above from 1999 earlier)

Yep, you're right, SOHC, my bad, thanks guys. Going to pull the motor and open it up for "fun". if the parts are in good shape and the damage is minor I'll rebuild the existing motor, if not, off to the bone yard for a swap out. Thanks for the advice!!:D

you can actually use any EJ25 block and bolt your heads to it, but earlier EJ25D "DOHC" short blocks with SOHC heads require thick headgaskets to keep the pistons, which clear the block, from hitting the heads. but i've done it before.

if you remove heads for any reason on a SOHC engine - be sure to use the Turbo EJ25 headgaskets, they don't leak like the non-turbo headgaskets.

Grossgary,
What is the newest I could/should use for a short block?
Here's the deal.

Scenario #1
HG set - $200
Short Block from bone yard - $130
Total - $330

Scenario #2
Long Block from bone yard - $170

Situation - 2000 (original) heads just redone with shop and in great shape.

I am cheap, but want a decent fix. Since it's winter I'm kind of being a vulture and waiting for a good crash to deposit a potential motor in my local pick n pull.

Advice?

Thanks!!
:D
