head bolt question
what torx bit do i need for pinto head bolts, the new bolts have the 6 pt star pattern not the multi-point pattern like the old ones did.
is it a t55 bit? i measured from the inside edge of opposite points and it came to 11.24mm if thats any help.

Make sure that you've got a good bit. I used a Halfords Pro bit for my Pinto head bolts and then discovered the design fault - no matter what
the size of the bit, they all neck down (or up) to a (6mm I think) hex which is then permanently mounted in its base. The hex on mine snapped doing
the head bolts - luckily I had another one in a cheap set that doesn't have this problem.

sorry alex,
talking about head bolts do you think arp bolts are really worth it,
i mean its 13quid or 80quid
with arp do you tighten the head bolts more than you would with std bolts

im not using arp head bolts, mine were £12 from local motor factor, can't really see the point in spending £80 on arp's for a standard
pinto! if you are going to turbo yours it might be worth the investment.

ARP bolts are a bit overkill. IMO
I have a couple of snap-on torx bits (the only snap-on stuff I own lol) specifically for doing pinto head bolts and sierra diff rear cover bolts
