Pistons frozen to cylinders in a 1600dp

Hi,

Working on that `71 Ghia, I have the engine torn down, but pistons 1 and 3
are rusted/frozen to their respective cylinders. Any reccommended methods
for working them loose? I tried the rubber mallet on the fins but it didn't
make them budge.

Thanks.

-Alex

Frozen to the "pistons"? What happens if you turn the engine
pulley? If the cylinder lifts off the case, slide a block under
both sides of the cylinder and crank it back.

Your pistons are frozen to your heads, then?
My bug experience is limited but I recenty stripped my engine down and the
heads came off easily.

A couple of months ago I did rebuild an outboard engine and would imagine
the same applies to bug engines.
It also had both pistons stuck to their cylinder walls. Spray it with good
penetrating oil first. Place a block of wood on top of the piston and tap it
down with a rubber mallet all while turning the flywheel with a wrench. Be
careful with the already liberated pistons: if they are floating around,
guide them back into the engine as it starts moving. Eventually it will
break loose and move freely.

Pistons frozen to cylinders, I mean -- Sorry, my brain is jammed in park.

Thanks for the replies, will try the penetrating oil later this week when
exams are out of the way.

Yeah, pistons 1 and 3 are frozen to the cylinder walls, or vice versa, and
the cylidner travels with the piston when I turn the pulley. Was also
surprised that gasoline shot out of the fuel pump as well, the car's been
sitting for sixteen years and was drained of everything else.
