i dont see any hole in the block. when i said "hole" i meant the cylinder. im hoping it just needs to be bored over and have new pistons and rings.

im going to talk to a mech tomorrow about it. im hoping that i can pay him for some of his time and he will help me put it back together. he loves merc and has a shop full of tower of powers.

Evan,
It seems very strange to me that a piston can go thru a cycle and not put say 30 or 20 on a dial. If it`s the no 1 maybe a crank shear? Not trying to be doom n gloom here.

i know. maybe i need to inspect the head a little better. maybe head gasket is destroyed? im still hoping nothing serious because all the pistons move.

Ok that was a dumb thought. If all the slugs are moving how do you get no comp. #?

I feel the comp # should register if you have any crank # if not sheared.
I`ll be pulling my PH next week and let you know how things go. I love twisting and learning.

Cheers and let me know if I can help,
GFS

Even with no rings you would still get something on the dial. I paid $300 / $50 per hole 4 years ago. Went 20 over. I put about $2000 in it including bearings.

I take that back. I did a little experiment. It takes 30 psi to open the valve stem in my compression gauge. You probably have compression just not enough to open the valve stem on your gauge.

what did you put in it for 2k? i want to try to reuse the crank and rods probably. just pistons bearings ans=d gaskets and those reeds esd was talking about and remove oil injection.
