I have just modified one of the original Head Nut Tools and sent it back to the customer. In his particular instance, there appeared to be a clearance issue. Job done! Hopefully happy customer!!
I am surprised that there has not been more interest in this Tool. Not just as a supplier, but from the point that I really believe more Alfa Montreal Owners have not checked the Torque on their Cylinder Heads, probably in more than 40 years!!!
After my personal experience, I would go out there and make sure that the Cylinder Head Nuts are properly Torqued up before you have a Coolant leakage at the Head Surface / Block interface. Whether you buy a Head Nut Tool from me or not, please check the current Head Nut Torque settings. You may be lucky and have a friend with one of the tools, whatever...
