Thanks both of you. An exact reading will help some more. I've got an issue.
My k301, is 44 years old, and has never been apart. I can't afford a proper rebuild, so the piston can not be removed IE: ovaling of the cylinder, etc.
It has a head gasket problem, where the area was leaking for so long, it left a rusted depression in the block, and even a new gasket after minor filing didn't fix it.
If I send it out to be decked, I'll most likely have to gut it, which is a no no.
So, I had this crazy idea.......duct tape the crap out of it, use my small hand sandblaster and clean the rusted depression, then furnace cement and when hard, file, and plate sand it.
I'm not positive about how it will work, but despite the redneckness of it, it may work.
If not, I take it to the machine shop.
I just don't have the time to go without it for more than a week, and unless decking can be accomplished without tearing it down, It just won't happen.
The cement I use holds up to my stove hitting 650-900f regularly, and doesn't breakdown.
