'98 legacy with a 2.5 replacement engine source?

Asked by Mar 31, 2012 at 11:32 AM about the 1998 Subaru Legacy 4 Dr GT AWD Wagon

Question type: Maintenance & Repair

My Legacy overheated bad and melted some plastic parts.  Mech said should replace engine, which I am fine with
due to miles and age.  Jasper doesn't have any 2.5l to fit  my car.  Mechanic doesn't have confidence in any others.  
Are there other good rebuilders for Subaru, or factory replacement sources?  I like my mechanic but don't want to
give up on my old Subie.

I'd get a second opinion. If all that was showing was some melted engine cover and any shrouding in the engine compartment, it's worth the couple hundred bucks to have the internals of the motor scoped (kind of like an endoscope for motors). Either that or have the cylinder head completely removed for a visual inspection of the cylinder walls and piston rings. The scope is far more accurate in terms of find hair line cracks in the block or cylinder walls.

Radiator crack caused the coolant to drop below the thermostat, so it was reading fine, but the engine was real hot. I know the gaskets go bad, the mech said heat resistant plastic pieces near the plugs had melted. Not an engine guy myself, but would a scope show warping of the cylinders? Just dont want to sink money into reassembly if a new motor that doesn't have 150k on it can be bought.
