Does anybody know the size of the rocker cover bolts

My "mate" has just overtightened and snapped the near rocker cover bolt on my 300tdi. It's snapped just below the bolt ie when bolt is removed the bar fills approx 95%
Can anybody suggest a repair!!??
Thanks in advance

you will need another err4687 as it secures rocker shaft as well ,you can drive it as long as it isnt losing oil

Thanks for that James but won't the replacement fitting not reach the snapped stud?

to fix properly, rocker box needs to come off the snapped stud removed and new one fitting, it has a nut at the bottom end to secure the rocker shaft to head

Once again cheers James
You don't know the part number for the stud do you by any chance
Lol

yes

you need top undo the cyclone 8mm socket ,hose clip on breather pipe, screw driver or 6mm socket, then just remove the 3 or in your case 2 rocker cover nuts, if you lock 2 m8 nuts together you can just nip new stud up then remove and use the proper flange nut to secure rocker shaft,once done smear some silicone sealant around cyclone o ring before refitting it
