well, the coils are out, the aero-kroil has been sprayed, and the new SP515's and boots are ready to be put in. thought about starting tonight...then i realized it's friday the 13th. better wait until tomorrow.
couldn't take the suspense. waited about an hour with the kroil soaking. then took my Milwaukee M12 cordless impact on low setting and buzzed them all, had about a total of 12" of extension/universal for all but the back plug on each bank. they didn't move, so I buzzed them again on the high setting, just till they started to move, some might have gone a full revolution before I could stop. anyways, pulled #5 out, all in one piece! better quit while I'm ahead and let the kroil work it's magic of creeping into places 1 millionth of an inch
