cylinder head.
yah i removed the cylinder head, and i turn the pto to move the pistons etc. and i saw some scratch just on one cylinder block, the other one looks like in great condition. / the oil filter tho is empty, means no oil goes to the cylinder. i'm just so stupid not to put oil on the reservoir because i saw that there were still half inch of oil inside it so i ignored it.
the oil inside is green in color,wonder what kind is it????
