I have a 2000 Kia Sportage that has been seriously overheated twice (that I know of). I got it used with 160k miles. It has 252k miles now. The first time it overheated the head warped. I had it machined and all was good for 2 years. The second time (right now!) I got a reconditioned head. When I pulled the old head I noticed some scoring on the front wall of the #2 cylinder. It's fairly smooth until the very top of the bore, but then it's noticeably rough between the area where the upper compression ring and the oil ring would be at the top of the stroke. In the image that's not glare- it's a different texture. With such high mileage I'm really not wanting to put any more money into repairing the bottom end. Is scoring like this common? What problems might I expect if I leave it like it is?
