Question US '98 EJ22E...Phase I or II? interference??

I recently bought a MY1998 Impreza L sedan with the EJ22E 2.2l engine. Is this a "phase I" or "phase II" engine, and if the timing belt breaks is there any chance of valve damage?

Thank you!

It would seem that this motor exhibits qualities of both Phase I and II. My understanding is that it fits more appropriately in the Phase I category due to the placement of the thrust bearings, and rocker roller cam followers with screw-type valve lash adjustment. It does, however, have the single exhaust port which is more like the Phase II.



Yes, I am responding 8 years later. This is because I use the search function

screw type valve adjustment is phase II and was not released until 1999...

EJ22E for the 98 year is still a P1 engine so there is still clearance btwn the valves and the piston in teh event of a belt failure.

I found this:
http://ej22.com/

I've read this somewhere else too, but not sure the info is correct.

I think starting in 97 the clearance was eliminated, but they were still phase 1.

So OP, of my info is correct, you have a phase 1 motor, but if the timing belt breaks the valves would still get trashed.
