The movement of the piston from BDC to TDC.
Blow by is caused when combustion gases get past the piston into the crank case. The cause will be piston, rings, or cylinder wall.
piston slap is when the piston inside the cylinder is somewhat smaller than the cylinder bore. when the piston moves up and down, it ends up moving side to side too. this causes a knocking/slapping sound as the piston slams into the cylinder walls.this can cause harm if the play between the piston and bore are significant, otherwise it's nothing to worry about. if the car is hammering you might want to take it to a garage.Piston slap is the piston lose is the cylinder and it is making a rattling noise.Hope this helps.

Yes, a scratched piston will cause problems with compression. It scratches the cylinder wall and causes wear on the rings.
Yes a 1998 mercury 200 efi outboard vapor can lock. Most of the time the issue can be traced back to the quality of fuel put into the engine that can cause the vapor to lock.
No. Your piston(s) are hitting your cylinder wall. No. Your piston(s) are hitting your cylinder wall. No. Your piston(s) are hitting your cylinder wall.
Oil !
One cause is that the cylinder the caliper piston moves in has scores - grooves worn in the cylinder walls that the edge of the piston is catching on. One of the easiest approaches would be to replace the caliper with a remanufactured / rebuilt one.
excessive piston to bore clearance means that the gap (tollerance) between your piston and the sidewall of your cylinder/block is too large. usually will cause blow-by. the burning of oil, and dark exhaust smoke. also may cause the engine to have a weak compression stroke
A hole in piston is caused by extreme heat! most likely cause is coolant being introduced into the cylinder during combustion from a leaking head gasket,faulty intake manifold gasket or a defective cylinder head!
sounds like your engine needs a valve job worn piston rings would also cause low compression ,but not cause the backfireing
