Howdy All,
As part the head gasket replacement project, I need to address a =
wallowed-out and stripped cylinder head stud hole in the block.
(If you were standing on the manifold side of the engine, it would be =
the one furtherest to the front, on the manifold side.)
A stud goes in straight up and down until the top of the threads are =
even with the block, but it wiggles like hell.
As you tighten the stud down further, the wiggle starts to go away, but =
the whole thing starts to cant back toward the rear of the block.
This make it impossible to slide the head down over the canted stud.
To fix this I intend to install a coiled insert. (drill just 1/32=E2=80=9D=
oversized, tap, install insert).
I am hoping that someone from the list knows of a drilling jig/guide for =
the drilling phase.
I know better than to attempt drilling out cast iron without a steadying =
device of some sort.
Any and all tips and advice are welcome.
The hole is 1 5/16=E2=80=9D deep, and the threads of the stud measure =
3/4=E2=80=9D.
It is basically threaded top to bottom.
Thanks in advance.
I hate it when you have to fix the unknown thing to fix the known thing.
Kind Regards,
Guy D. Huggins
