Seen this piston drop out on 12 cylinders big ship engines, know it will work on 6-71, Detroit. Easy with access panel.
Thinking about a 6.5 Detroit, pull oil pan, loose two bad piston, with water damaged rings. Route injectors back to tank, pull push rods.
Any ideas?
 
A problem that comes to mind is the firing will be uneven around the 360*, presumably, will that increase vibrations ?
 
Don't forget the hose clamps and strips of rubber around the crank shaft so as to maintain oil pressure. I have done this to an engine it ran for many hours.
 
The engine will vibrate more. I would keep the rpms down and not long term. The crank isn't designed for imbalance. The missing cylinders are normally powering cycles in other cylinders.
I did this on a 6 cylinder Enterprise. It ran with more vibration, but was only for a few hours. In Vietnam I ran a 671 for about a half hour that had taken a direct hit from an anti tank round. It didn't run good, but it got us home. Low air box pressure. Only did about 1000 rpm.
