Can someone give a helping hand thanks? I hav a damage(deep scratch ) in one of the cylinders and it appears no over size pistons or liners available. Wonder what is the material of the liner, iron(cast iron?) or something else? If get the info maybe possible to repair/ resurface...or even install new sleeve? The part number is 880504A12 and these are the said to be the same blocks as on the older 4cyl Verado engines. Any help highly appreciated.
