[QUOTE="dfb, post: 123882, member: 11792"] Great to see your progress getting through this motor job. There is no magic in there but attention to details are key. I searched on Rockauto for that Hastings number, they do list it also in bore oversizes of .020, 030, 040 and .060, no standard size listed. You will need to know what size to order the correct one. If the bore has not been oversized you will need to check and likely file fit each ring to the bore it is going into checking it's end gap at the smallest dimension{most likely toward the bottom of the stroke}. For the topic of conversation, a proper crosshatch pattern is necessary for oil retention on the cylinder walls to provide for good ring sealing. To clean up the grit after honing you want to scrub the bores with hot soapy water and a brush. you know you are done when you can take a paper towel sprayed with carb or brake cleaner and wipe a dry bore and get no dirt{the towel will remain clean}. It can be time consuming but will yield long lasting results. [/QUOTE]
