Best to use a 1/4" drive torque wrench.

Carlo,

If these studs shown in your photos are 6 x1.00mm thread pitch (as they are on virtually all DOHC Ferrari engines), the torque figures I'm supplying are correct...

If still in doubt, call another dealer, to be safe.

David

Carlo,

In theory, the torque figure should be the same, as the thread diameter and pitch are the same. However, the nuts and washers used on the cam journals are of a higher grade than what is typically used on the valve covers.

So, to best answer your question, I use a slightly lower torque of 72 inch-lbs on the valve covers and end plates. It is very easy to over-torque the valve cover studs...and pull the studs out of the aluminum heads, so caution is in order.

Saldy, in all of the work shop manuals that Ferrari has produced over the years, they have been somewhat elusive as to the precise torque required on these fasteners. Standardized torque tables and common sense come into play here...

Regards,
David

Yes there are Torgue values fo

Yes there are Torgue values for the Bolts you mention & yes I use Locktight (Blue) on the Cam gear bolts & a small swipe of copper silicone on the oring (mostly as a lubricant to prevent the oring from galling & as a touch of extra protection against leaks), locktight is not neccesary on the tensioners because they use locknuts and spring washers.

I'll have to look up the specs as I don't try to memorize some things, because a smart guy once told me, unlike the human memory, the book always remembers things exactly the same no matter how many times you look at the page!

Have you been able to find the torque specs for the cam bolts and the timming belt bolts.
