Still couldnt get that Continental F-163 engine unfrozen, so had to
pull the head....yes..it had at one point gotten water in it...

Nothing seems to be badly damaged...but some valves appear to be
frozen, as well as at least one piston..the worst is #1..the one with
the fluid in the bottom of it in the above pictures.

I left 5 studs broken off in the block getting the head off...but
there are a fair number of threads standing above the block, that I
can probably weld nuts on them and work them out...Crom..I hope so..

Any suggestions other than threading on nuts and then welding them on
and hoping the heat loosens them up? I used a pick yesterday to clear
some of the rust around them, and sprayed PBlaster in the gaps..along
with the valves

I took a chunk of wood, and a hammer and tapped each piston firmly,
repeatedly spraying PBlaster around the sides of the pistons. Two of
them appeared to not be frozen, the third (far right) may be so, but
the far left one is still pretty much solid.

Cylinder walls on the right one, is smooth, has no ridge, no scratches
and is well polished, may have been honed at one point with a ball
hone..or there is no wear at 2400 hours. Left cylinder has surface
rust, not real thiick and a quick pass with a wire brush in a circular
motion got down to polished wall . Down low...shrug..it may well be
pretty pitted.

At this point..I think Im going to have to put the machine up on
blocks so I can drop the pan, disconnect the conn rods from the crank
and drive out the pistons from the bottom....I dont think they will
come out the bottom, will they?

Ill get a fine wire wheel and wire "bob" and do the faces of the block
and the head, and get out the crud and carbon from the various
recesses. Unless someone has a better idea?

Im not an engine guy...this is the 2nd or 3rd one Ive ever pulled down
this far by myself, fortunately this is a stone simple engine


Any suggestions at this point would be greatly appreciated

Ugly, but seen worse. Above advice spot on,
Get the block out & on a stand/bench. Get it
stripped out and hot tank it.


Possibly rig up a hyd jack/press over the stuck piston,
..
Carefully press down on piston. Seen a brute
bust out stuck pistons, try and avoid that..
