Back in '16, I was given an engine that I let sit on an engine stand with NOTHING being done to it except for a little cleaning and dismantling. This month I decided to buckle down and try to get it in working order. It was going good until I decided to find out if it would turn over. So using a big DeWalt 1\2", 1100 ft. lb. impact and the harmonic balancer bolt, I tried it. NO GO!!! I've read through several forums and YouTubed several videos and basically came to one conclusion: soaking with MMO, kerosene, ATF, acid, vinegar, etc. for hrs. to several months. I know that, looking back, I've already wasted 7 yrs., so what's another 3 or 4 more months? I really want to get my own transportation and a motorcycle doesn't do me any good in winter. What I'd like to know is: Can I remove the crankshaft without first removing the oil pump (I'm unable to remove oil pump because crankshaft can't be repositioned) and then (if that is doable) knock the pistons out? When I get the pistons out will the engine need to be bored or can it be honed? New pistons?
Thank you in advance for any and all advice.
