Torquing up headbolts

[Lunner]

IIRC these have to at some point be done to 25Nm, but all the 1/2" torque wrenches i can find go from 30NM, mine included, can't impagine an extra 5 Nm is gonna make that much of a difference.

Also my T55 bit is 1/2" drive and i can't find any 3/8" drive, whihc the smaller range wrenches seem to be

[Coops]

i blagged mine, bad practice i know but its been safe as houses for six months, and i used a 30nm min torque wrench

thats good enough for me

over tight is better than undertight

i have a 3/8 drive snap-on (oooh check me!) torque wrench for engine building, goes nice and low...its all thats needed.

machinemart do similar at very low cost.

u might have trouble getting a 1/2" T55 socket down the hole if the cams are in place. Could only use a 3/8" on mine.

Halfrauds sell a "professional" 3/8 torque wrench that goes from 5-60 iirc, very good and cheap. u could always use it then take it back say it was wrong one lol.

Bit or cardboard??

I have a spinning piecxe of plastci that you hold with your finger

It fits down in there as i removed them with it, cams are still off the head, will just fit them when the head is back on, hard doing everything with the head sat on end so as not to damage the skimmed face
