True Classic
I understand why some people think that the 17mm head bolts used on some 1500 engines are TTY. The Fiat workshop manual specifies that the torque turn method is used to tighten them.
But even though the Fiat workshop manual is very comprehensive it does not specify that those 17mm head bolts are TTY, or that they shouldn't be re-used.
Does anyone have any information, other than the torque turn method is specified in the workshop manual, that definitively specifies that the 17mm head bolts that Fiat used in the 1500 engines are indeed TTY?
If they are TTY - fine - everyone should know that. But if they are not, everyone should know that too.
