There's some great stuff on here.... having a bit of a nightmare with the soop.
Last BHG - I had the head replaced as well and asked Mr T to sort out the exaust manifold bold holes for 5 & 6... I thought they would tap and use bigger bolts but they just used helicoil and unfortunatley both have now gone again.
So it's back into the shop next week for a fix (and a new clutch) ouch!
Anyway thats why I joined, to get a bit more info and look for any other solutions.
all the best,
well, ive personally done countless helicoils with no failers.i can only amagine did the macheinest drill the hole comletely to the back of the hole ?and did the coil flush all the way in on its own.?were the studs installed all the way in and tightend?
