It's a good simple engine design. Odd cracked ring in the engine, but can happen with bad gas and detonation and numerous other reasons, but is the cause of the taper. The less tension and more blow by, heated that cylinder more than the others. added more carbon to the cylinder walls and crankcase to pollute the oil and micro abrasives on the cylinder walls. Snowball! LOL!
If you like the truck, it's well worth it if the rest of the truck is good. Makes more sense with the retarded car prices now!
