Trim Cylinder caps stuck

I noticed some oil around the dust seal on my trim cylinder. I replaced the trim motor today. When I push in on the trim rods I see a very tiny amount of fluid bubble up around the dust seal. I assume this means I have a bad seal? Since I already have the trim and tilt off to replace the motor I figure its time to replace the seals. Unfortunately the caps are not coming loose even with the spanner tool and a large breaker bar. What are my options here? I already have new caps so I have no problem butchering up the old ones if need be. I was thinking maybe large channel locks or an air chisel to knock this thing loose. I read a post somewhere that said some yamaha techs actually know how to cut them out? That would be a last resort of course. Is heat ok or could that cause other problems? Any help would be appreciated. The motor is a 96 yamaha 250.

If the mtr is used in salt water, you may want to try some heat.

I to have found the Mapp gas works pretty good. I never use Propane.
