Hello guys, got a vehicle with no history. Overheats after 20-25 min of driving on highway, or 10-15 in the city.
Subaru Legacy Sedan 2006 Automatic Non turbo.
Pulled the engine, took off the heads and found the crack in two heads in "unusual place for cracks". Was wondering what you guys think, if it's a big deal or not; repairable or fixable, can I get just the top parts?
1A: looks like a crack, don't know if it's deep or not.
1B: looks like a tiny hole, don't think it's deep, also not sure how important it is..
Also, first of all I want to do it right without spending much money (as we all are), but.. How important is it to take the heads to machine shop overall? (adjusting the valves, checking the pressure, cleaning) In my case do I have to do it, or I can just clean them up carefully, change the valve seals and good to go?
I guess I would say if you can put yourself on my place, and ask other questions if there is
Any suggestions would be really appreciated!
