Rebuild or replace engine on 2012 Subaru Legacy
3 Answers
The problem with a seized engine is you won't know how bad the damage is until you tear it down. A bearing could have spun damaging the bearing surface and require machining to repair. Just to prep the block and heads for rebuilding a seized engine can mean extensive cleaning, checking and potentially machining. A remanufactured engine can save you a lot of costs and time in the long run.
I would probably buy a new short block from Subaru. You can rebuild the heads and install them on the new block.
If it has less than 100k miles on it take it to a dealer. Subaru is replacing our 2013 legacy engine. They did an oil consumption test on ours and it failed. That is why they are replacing it.
