All good - he took it back to the machinist in question, who admitted he did it and fixed it no charge.

We're putting the motor in on Saturday, and hopefully starting it also!

Gidday all!

Thanks for accepting me onto this forum, much appreciated

My father is doing up an FC sedan. He's progressed fairly well: the bulk of the body is done but for a few patches of cancer, he has his interior sorted, wheels/hubcaps etc.

He's run into a bit of a pickle tho:
He recently had one of the rocker gear bolts seize in the head. He got someone local to drill it and tap it out. Other head work was done (valve grind etc).
When he re installed the head, he saw that some water was leaking out of the rocker gear bolt, almost like the drilling had pierced a water jacket.

My question to you gentlemen is: is this likely what the problem is, or is there something he hasn't done that needs to be done, to prevent this happening when re assembling a grey head?

Thanks in advance!
