jam007 Posted August 18, 2019 Share Posted August 18, 2019 It appears to be the OCV for the exhaust cam Link to comment Share on other sites More sharing options...
Setnev Posted August 22, 2019 Share Posted August 22, 2019 Exhaust cam AVCS, which tells me that this motor might actually be an EJ20X and not an EJ255. Link to comment Share on other sites More sharing options...
h2dave Posted August 22, 2019 Author Share Posted August 22, 2019 How can I tell what it is for sure? Link to comment Share on other sites More sharing options...
Infosecdad Posted August 22, 2019 Share Posted August 22, 2019 Look on the top of the engine block for an EJ20 or EJ25, the lettering should be about an inch high and you can see it from above with a flashlight most of the time. Also, that timing belt cover seems pretty smashed up; that's not good, and really should be sealed to protect the timing belt. Link to comment Share on other sites More sharing options...
dgoodhue Posted August 22, 2019 Share Posted August 22, 2019 If you just bought it, bring it back. Subaru didn't make a EJ255 JDM Legacy motor, it likely a EJ20X. Let someone else deal with this headache. Link to comment Share on other sites More sharing options...
