im really not a mechanic and dont know as much as those before me (picture me bowing to those with so much knowledge) but i recently had to get another h22a about 2 months ago because of a broken timing belt...pistons values and value springs all smashed...i also though i could save the head but once the engine was opened it was all bad so the engine swap was the logical choice she can easily get another engine with 130k for 400 to 600$ depending on what is equipped and what she can salvage
