Hello all,
K75 is slowly coming along, Getting ready to fit a replacement cylinder head, the manual states to torque to 30 Nm give or take 4, then to wait 20 minutes, then torque to 45Nm give or take 5.
Any advice on re torquing after, say wait for 24 hours then re torque to final figure, or after x amount of miles up the road?.
Previous experience with alloy car engines, Reliant in particular, I would re torque after 24 hours, never had an issue there.
So, just wondering what's best practice for the K, are they good to go after the second torque, or do they need re torquing again, just to be safe.
Thanks,
John
