One block looks like I had a repair on outside from a past light freeze situation is my guess, has no effect and clearly been that way for a while with no issues but does get a little "wet" outside there you can easily epoxy it and be fine or leave as is, I run them, post compression tests, also have videos of scoping cylinders I can also send, I am as thorough as can be. No idea the hours but looking at cylinder and oil is very clean, can't be many, Located Olmsted falls Ohio for pickup 5800.00 each cash, 11,000.00 for pair I also have another set of marine big blocks here you can also search my ads to see them or ask for the ad.
