bratman18 Posted March 26, 2009 Share Posted March 26, 2009 How can I tell if EJ22 is interference engine or not??? MY 95 vs MY97???From exhaust ports? There is a difference in the heads. You'll notice the plugs are located differently between the two(or mine was). 97 and up is interference I believe Quote Link to comment Share on other sites More sharing options...
idosubaru Posted March 26, 2009 Share Posted March 26, 2009 95 is not interference 97 is interference other than that, i'm not sure of any tell tale signs, but it would be a good thing to know for the 96/97 years to be sure. Quote Link to comment Share on other sites More sharing options...
pearlm30 Posted March 26, 2009 Author Share Posted March 26, 2009 The EJ22 in one of MY 95 legacy has a dual port exhaust and I thought MY95 and 96 have single exhaust port, so that lead me to think interference EJ22 has dual port exhaust:confused: Maybe someone before me replaced the engine with a interference from 97???

subaru360 Posted March 26, 2009 Share Posted March 26, 2009 95 was the last year for dual port EJ22. non- interference. 96 was the first year for the single port EJ22. non-intereference 97-98 was single port EJ22. interference EJ22 went to phase 2 in 99. all phase 2 is interference.

pearlm30 Posted March 27, 2009 Author Share Posted March 27, 2009 Thanks for clarification. 95 was the last year for dual port EJ22. non- interference. 96 was the first year for the single port EJ22. non-intereference 97-98 was single port EJ22. interference EJ22 went to phase 2 in 99. all phase 2 is interference.

idosubaru Posted March 27, 2009 Share Posted March 27, 2009 yeah the exhaust has nothing to do with whether it's interference or not. all 1995's are dual ports (and non interference). all 1997 and up EJ22's (actually all 97+ Subaru engines) are interference.

pearlm30 Posted March 27, 2009 Author Share Posted March 27, 2009 Thanks. But are there any physical differences by just looking at them??? yeah the exhaust has nothing to do with whether it's interference or not. all 1995's are dual ports (and non interference). all 1997 and up EJ22's (actually all 97+ Subaru engines) are interference.

bratman18 Posted March 27, 2009 Share Posted March 27, 2009 Thanks. But are there any physical differences by just looking at them??? Like I said, the plugs are in a slightly different location because they changed the heads Quote Link to comment Share on other sites More sharing options...
