I have recieved a b18a block for free with a hole in it where coolant leaked out that you would have issues fitting a dime through. I am planning on resleeving the block as long as it is possible to just weld the hole up and continue to use the block. Is it worth it to get this hole fixed or should i just get a new block. If so any recommendations on where to find a good ls block in the Phoenix metro area. Thanks a bunch
