I have a fancy "special tool" for removing the cylinder head---it comes in pairs and is called "right and left hands"---seriously, you do NOT need a special tool to remove/refit the cylinder head.I've got the fancy shop tool; I bought it for its rarity value but I've never needed it.
Personally, I would first of all fit the rocker back into the pushrod, tighten everything down, check the tappet clearances and see how things go. The torque for the rocker-shaft nuts is:--18 ft lb (25 Nm). The problem with tightening these 2 nuts up with a torque-wrench is the length of the stud above the nut----a 13mm socket THAT long will be difficult to find. You might be able to make up a simple tool utilising a box spanner and, with one end closed up to accept the drive of the torque wrench. I must admit, I have built enough of these engines up that I just do these 2 nuts up--tight! Never (yet!) had one come undone. When you refit the rocker-shaft, make sure that the part that goes over the oil-supply (to the rockers) tube is sitting correctly---I have seen it where the top casting for the tube has not been fitted over the tube, with a consequant loss of lubrication to the rockers.
Thanks for this. I got to the bottom of the issue:
That was the problem w/ my head, shown in my link.
Wingless,
I use "self-tapping steel inserts" for this type of job.This is a proceedure that the careful mechanic can carry out himself very easily. They are very strong,and in fact "Abarth factory" used these inserts themselves, I accept that you are not probably able to buy them from the same companies that I do (MEMFST or "The Steel Insert Company), but there must be companies that sell similar products in the USA. If you get really stuck, contact me directly and I will see what I can organise for you ( [email protected] )
I may need to see about getting one of those tappet tools, that looks slick!
