Replace 2004 Subaru Outback engine or move on?

I suggest you DON'T shoot a dead horse... Heres' a typical post "I have owned three Outbacks over the years, and this is my second one to develop a head gasket failure. I had the car in to the dealer today because I am moving across the country in a few weeks and wanted a transmission flush and oil change. I told them to check things out while they were in there, and low and behold, I had a small oil leak on the drivers side head gasket." Common issue for many years of Subaru. "shooting a dead horse"means that you are repeatedly doing or saying something that is pointless because of the .the fact its dead already.

Put a bullet in it and move on.

The oil is constantly in contact with the head gaskets on these engines. If the oil gets contaminated/dirty and left for long enough, it erodes the gasket material. I didn't know this until recently. As far as sourcing an engine, 3k for a used engine is insane! Check car- part.com - 3k for a NEW engine.. meh, might be a good price? (just checked - yeah, reman units on rockauto.com are 3300 bucks for 2.5). I would be more inclined to fix it and know that you have a good vehicle for years to come, since you've already done other things to it. Verses buying another used vehicle with unknown history and potentially repeat this scene. The heads are prone to warp with this scenario, but idk about the block.. it has to be checked though. If the block is okay, replace/machine the heads and roll on. Read more here and check out the video: https://allwheeldriveauto.com/subaru-head-gaskets-problems- explained-part-ii/
