hello.
You are a lucky one since you found the manual. I would be grateful for you to give me the address where you found it.
Well, it will be easier to help you with the knowledge you have, I got to work for disarmament.
To penetrate the crankshaft, a special tool is introduced by a side plug of the cylinder block that the crankshaft locks that lock is fair with the position of the piston nº1 in its PMS, and for the cams axes they remain with slots that carry in their ends horizontally parallel to the upper surface of the cylinder head, that slot is not in the center of the axis. That has to do with hearing.
To do a good work of the cylinder head, you must first lower the oil carter, disassemble the crankshaft pulley, the water pump, and the distribution front cover. With all this disassembled it will be very easy to disassemble it. The head of cylinder heads are "Torch" do not try it with a hexagonal dice.
Good luck and then we continue ...
