Hi,
Does anyone know the exact procedure for putting on a cylinderhead of an M130.920 engine? (6 cylinders, gasoline)
Anything else after applying the torque (in steps), for example?

Hi Martijn,
for a 280S :-) (and all other M130 engines) cold engine M10 (14x) bolts 10 mkp = 98 Nm warm engine M10 (14x) bolts 11 mkp = 108 Nm
small M8 (5x) bolts torque with 2.5 kpm
1 mkp = 1 kpm = 1 kg*m= 9.8 Nmoil the thread. + heads + rings lightly.
Order: Work from the inside out. fasten the outer site of the engine the latest.:
First inner 2 than the 2 next to it starting with the distribution site. (that is bolts fastened)
2 bolts directly next to the fastened bolts at the distribution site again and then the opposite site.
- fasten in the correct order (torque for cold engine) 20 degrees Celsius)
- start the engine heat water temperature to 80 degrees Celsius. keep it running for 5 minutes. retighten in correct order to the given torque for warm engine.
- retighten again after 300-1000km, untighten ONE bolt and retighten to spec. then the next bolts ONE by ONE.
Good luck,
Maurits Obbink
