i set wd40 in the block last night.
tried this morning and it did move slightly.
enough to remove the caps and then the crank and then the pistons were able to be hit from both sides. a few taps each way more wd40 and they slowly came out.
i did use a whole can though and you are right. it doesn't seeem to penetrate much.
now i have another issue.
the no.1 piston looks like it had spun a bearing., the rod has been eaten out on the side not much left of the bearings and the crank journal has a very rough feel to it compared to the other journals.
sigh
so much for cheap rebuild.
hey are 18rc rods the same as 18rg?
i will search but if you are quicker...
