snapped a bolt!!

[vwmk3jon]

Snapped one of the bolts that bolds the camshaft down. Its snapped halfway down so should be easy to get hold of. Is this just a stud like the exhaust manifold or is it a drill out job?

Nearly bloody there too

[dub-disaster]

Think there studs get a hold of it and carfuly remove it.

[Jezza-7]

yeah there just studs.

[vwmk3jon]

Thank jebus job for tomorrow.

haynes and torque wrench to buy next too

[vwmk3jon]

Sorry, i'm still on spot the dog. I'll send them your way when im done  

Yeah, just wondering if me ole mans got a torque wrench hidden somewhere? He does have the worlds weirdest 14mm socket tho!

Going to need a 0-10nm wrench John. I think these nuts go down to about 6nm.

The studs are M7, so abit of a pain to get hold of, M7 helicoil kits are about £35 if you need one. Not the end of the world but a pain none the less.

Remember the nuts are torqued, then angle tighten.

[Jezza-7]

i think i need this kit for my new head, where is best place to get them from?

[Yoof]

Local engineering supplies sorted me one, here's a pic of the buggers:



Sods law means I only found out once the engine was fully built...

Try to get the full helicoil kit, so you've got the coil insertion tool, and a little punch to snap the tang off at the end.

[GAF2]

heli coils are ok but you better off with going to a cylinder head specilists with the cam cap and get them to put an "insert" in the are a solid tube threaded on both sides and fitted with small hand tool. Much better than helicoils.

cheers grant

The thing i found atad scary was the fact it was very easy indeed to get it out. Only needed 2secs with a pair of pliers and hey presto. Surely they must be abit tighter than that?
