Questions:

 

If I am looking at an ad for a used Subie that does not indicate which engine, is there an embedded code in the VIN that tells if it is a 2.2 or 2.5?

 

Also, what is the latest model that had 2.2's?

 

And, are all the years of the EJ25 subject to the dreaded HG issue, even the Phase IIs?

 

Thanks, much

What year and model Subie do you have under purchase consideration? Forum members here will be able to tell you which motor is in the car without knowing the VIN.

 

As far as 2.5 motors with HG problems, it is the phase 1 with the most serious HG problems requiring HG replacement.

 

The phase 2 motors have some HG trouble, but it is more of a trace leakage of coolant to the outside of the engine. Phase 2 motors often receive a Subaru additive nicknamed "oatmeal" to stop the leakage without requiring HG replacement.

all EJ25's are prone to head gasket issues. you can start to debate around 04 or so but that's probably not even close to the years you're looking for.

 

of the two EJ25 issues, the Phase II failures are much less problematic. they don't cause overheating or leave you stranded.

 

there probably is a VIN code for the engine, but i don't see how that's a solution to the listing problem since fewer people put that than the kind of engine.

 

cars101.com should answer a lot of your questions, use that and take notes as you're shopping.

 

EJ22 equipped Subaru's:

 

1996-2002 Impreza's (not including the RS or WRX)

 

1996-2000 or so Legacy L's and Brightons have the EJ22

 

1995 and 1996 manual trans Outback wagons are the only OBW's with EJ22

 

 

1995 and earlier Legacy's
