I think vibration would bee about the same if I weighted the crankshaft correctly.

It would take alittle time to experiment as to what size would work or be needed.If it was small enough it should reduce pressure. If you can do machine work you could also cap open end and o-ring it to stop leakage. also drill and tap hole on pipe to have in and out connections.
I tried something kind of like that after I made my first engine but it still leaked to much. I also did finally find all the valves I need.

ya i'm probly just going to get a gas engine for it cause a friend of mind is going to sell his full size boat and I want to beat it with this one before it's gone. i'm going to try and build an engine though, I can't get it cnc milled any more now though
