Well, that's sort of NORMAL ! I have them break off frequently no
matter how careful I am. So, now you will have to get out the drill and drill
bits and start drilling them out and insert Helicoils. You will need to
source 35mm long Helicoils or stack the common short ones. The ones at the
front are not that hard to attack with a small air drill but the ones at the back
- WHOA !!!! I have a very small right angled air drill and a whole series
of cut off drill bits to do them ! Time consuming for sure but can be done
with the engine in the van. The other option is to remove the heads but then
your into a complete reseal job ! NO FUN ! Get the surface good and flat
before hitting the broken off bolt with a centre punch and try to get it as
centred as possible. Start with a 1/8" drill bit and be careful not to break
it off ! Then go up in size maybe 2 or 3 sizes so that you can rock the bit
back and forth to get the hole centred if it was not at the beginning.
Eventually you will get to the proper size bit that will allow you to run a tap in
there for the Helicoil. Be careful to not drill past the original depth or
you WILL go into the coolant chamber and then the head is scrap metal ! Use
only carbide drill bits !! Keep the drill bit in the bolt and DON'T let it
wander off into the aluminium (NOT EASY) especially at the rear !
>>>>>The worst has happened. After very patiently removing the nuts and
bolts =
on my wbx I twisted 2 off and still have 1 to go. They are flush with =
the head and have nothing to grab onto. What are my options with out =
removing the head. They are obviously not grade 5 or 8, but good old =
garbage grade 2 considering they twisted off with a minimum amount off =
force. Is it possible to helicoil these while in the van?<<<<<<<<<
