Ive got a 109 block I want to use for my current buildup. Only problem is its pretty rusty. Can the machine shop get all of this surface rust off the block and its passages??? I would hate to have a piece of rust go thru a bearing.
a good mach shop can put it in an oven and "bake" the block really good removes rust, paint,and all the other grime on it then you will see the damage if any the rust has done. if it is light bore and line hone may clear it up
