However like all other models try to stay clear of any subaru with the phase1 2.5L (DOHC), these engines are prone to head gasket failiure and piston slap.

I know this should be obvious (and is probably listed somewhere else on this site), but when did Subaru move to the Phase2 2.5L?
1999 for Impreza/Forester, 2000 for Legacy/Outback.
Phase 1 are DOHC with spark plugs that come straight the side of the heads between the camshafts, Phase 2 are SOHC with spark plugs that are angled upwards from the top of the head.
The easiest method to tell them apart other than model and year is to note the spark plug location and the size of the head, the DOHC are much larger and you can see space for two camshaft pulleys on the timing belt cover.
Usually DOHC is more powerful than SOHC, but in the EJ25's case the SOHC develops slightly more power, and also develops its power at a lower RPM.
