nice guide man ! just wondering i got a pair of bolts that said that I nead to just do the 40 nm first then start it and get it to 80 c then loosen it and then do 60nm and so one. Seeems quite strange for me to that that they say. cheers
Peter I have seen similar procedure for connecting rod bolts to ‘set’ the bearing before applying the clamping torque but never for head bolts. On large industrial engines we’ll set to a nominal torque first to set the bearing, back fully off, and then go up in torque steps alternating between the bolts to ensure even clamp.

Thanks. Sounds very particular, are they for a VW?

Video reversed?! Just looks weird seeing head bolts done backwards!
I think its just because of the way i had the camera facing and i had sped that part up
