Default Flex hone

Have a LY6 block I'm putting new rings in and going ahead and flex honing it to help the new rings seat. Just looking for opinions on how my crosshatch looks and any tips for me. I just did one cylinder so far.400 grit flexhone, 30 weight oil, cycling for about 12 seconds. Thanks

Looks pretty decent to me. Be sure to clean it really well afterwards with acetone and then ATF on a paper towel.

switch from oil to diesel fuel. Rinse a coffee can out and put enough in it to get about half an inch over the top of the hone when it's sitting still.
The deisel is easier to clean out and when it runs down it carries a lot of the sediment the stones are scraping off with it.

just make sure to keep that up and down action fast and to not sit still. Also, do your best to not run way past the bottom of the cylinder or you can damage the stones.

other than the little bit left at the top, you are doing fine.

are you having the crank polished and putting in new rod and main bearings?? What about cam bearings?

since you have it that far torn down, may as well do the job right and go ahead put new ones in. Peace of mind!!

I think after 15 months, he would have either found it or moved to a different block had there been a water jacket crack.
