Default Short Block Long Block Condundrum

Year ago 2009 WRX overheated. Indie tore down, inspected, replaced head gasket and rebuilt heads. 6 months later there is oil in the coolant but no coolant in the oil. Subie dealer says no idea, could need a short block. Take it back to Indie as it had a warranty and said need to figure out how to fix. He pulls it out inspects and can't find anything anywhere. Recommends long block to be sure....no kidding. Realistically, I get that, but any better recommendations out there on experience? Have a subie tuner shop near me that says, bring it here. Can anyone really inspect and be 100% confident that can locate the source of the oil getting into the coolant? Should I put in a new short block with existing heads or bite the bullet on the long block. $10K car is killing the wallet...any help is deeply appreciated.

No one will give you a 100% unless you put in a brand new long block. Is the block split? If you want to keep your SB i would have a Subi shop look at it and have them rebuild it. Sounds like Indie, guess that's the shops name, are retarded. They build you a block, it has issues and their reply to that is well we don't know so buy a long block. I would RUN from that shop.

I might be spoiled but with my shop I would just let them pull the block, take it apart and look. If its needs a long block I'd buy the used one on FB for 3k and slap it in and get charged for engine swap only but I have a real homie working in the shop. Even if you don't you're still only getting charged for pull, split, and putting it back in.

Please don't spend 10k on a fresh long block no matter what though, just read the same story on a different website.

10k is a load of money for an EJ and you can have a built lower end for that.

EJ255 block with internals but no heads (not long block but not short block what do we even call that lol) from Subaru, the shop price is $1,700. That's with fresh pistons rods and crank. Throw another $1,500 at it and you got nitrided crank, forged pistons and rods, and ARP studs. Another $600 and you got closed deck. Heads you can spend very little or a lot on but regardless $10k is a stupid price for a new long block.

Really it depends on budget and damage. I think regardless of what happens in the end, getting the engine pulled and at least the heads and pan pulled off of it is required if they think the issue is within the engine, so just go from there

I would get a new OEM ej257 short block and engine gasket set for your year car, have a machine shop pressure test your heads to verify they are ok.

Is that $3500 installed? If not, here have them ship it and it still going to be cheaper.

So, what makes you think there is oil in the coolant?

There was a similar post not that long ago.
- Guy had oil in the coolant.
- Subaru Dealer Mechanic told him he needed a new motor.

Turns out, the Guy * thought * he had oil in the coolant because of the oil-looking gunk in the coolant overflow bottle.

Turned out to be nothing.

So, what makes you think there is oil in the coolant?

Where in Canada? 6k from the speed shop must be a non stock build?

Only way to really be sure is to take a sample of the coolant and have it sent off for analysis. That would be step 1 if it were me.

Mods list would be helpful. If you're running a big turbo and stock head studs, that could do it, or even just a bad tune.

If there really IS oil in the coolant... I'd suspect:

1. Bad headgasket due to poor deck/cylinder head prep or torquing of the heads

another test route i just did for a 94 4runner, remove thermostat and see if it still overheats...if it doesnt, stuck thermostat, if it does, look at flow, bubbles in the cooling system, is the cooling system bled fully, faulty radiator cap, flow issues through block, radiator, airflow issues through radiator...lots of things can cause overheating...
