been opened up awhile

barbee6043, this is some shady stuff that I'm telling you!!!!! but it works! have done it many times!

My first mechanic job was working for a Japanese wrecking yard. he would sell motors and i would install then for the customers.

What the customer didn't know was that a lot of these motors were frozen up from siting all winter with out a carb or a air cleaner and they were rust welded.

we would pull the head, spray the head and sook the cyl with atf, pry the motor back and forth until it was free.


Used 36 grit sand paper and hand build a new cross hatch in the cyl, removing the rust. It worked every time except the time that i decide that 80 grit would be a little bit less harsh on the cylinders.
It came back a week latter smoking pretty bad.

when you have the rust removed, even if its pitted, you simply just keep adding oil to the cylinder and wiping it out when the piston is at bottom dead center, until the oil stays clean.

What you got to loose, but a set of gaskets.

The cam.........i have no trick for that, just replace it.
