    3b crank bolt??

    I plan to do my cambelt some point soon. However i have been told the crank bolt of nla.
    Its an m18 1.5 pitch 65mm. I thought they were the same as a t4 but they are 110mm.
    What do you guys do, cut it down?

        Wicked. Ill get onto febi.
        Yes they should be changed as they are stretch bolts and under massive torque.

          They are not stretch bolts. It has been discussed before:
