Hi everyone I am brand new here so I'm hoping I'm doing this all right? I've got a 1996 Subaru Legacy L with 250,000 miles and it seems to be leaking oil from everywhere at this point.i know it's leaking oil from some of the cam seals as well as the valve cover gaskets. Not sure if HG are leaking as it's hard to tell with all the oil everywhere. I'm getting misfires and its running rough on occasion. i feel like I'm at a crossroads with this car. I'm not sure the best plan of attack for fixing it? Here's some ideas I had And your input would be appreciated. 1. Pull the motor and essentialy rebuild it and put new engine gaskets in. 2. Buy a used 2.2 with less mileage and drop it in (if I can find another decent 2.2 with low mileage around here). 3. Buy a different ej motor as long as it's plug and play and bolts in. 4. Find a ej25 and build a frankenmotor?
