Broken exhaust stud removal...

[Gerard]

Hi!

Well, on Saturday I was test fitting the timing belt covers on my MC
engine along with the pulley and bolts and testing the fit of my crank
locking tool (2084) that I had made up a while back.

I hadn't paid much attention to the exhaust studs before, but looked up
and noticed one was indeed broken off in the head.

I just bought some stainless steel studs (+- $12 for 10). They had some
nifty stud extractors, but they wanted over $50 for them. I then bought
a new set of eezi-outs *cringe* and a new bit.

I need some advice on how to proceed seeing I already experienced the
broken off eezi-out *cringe* story when rebuilding my turbocharger.

I have a 3mm bit, but was thinking I should get a 5mm as well in
order to
use a slightly larger eezi-out *cringe*.

Would it be wise to also attempt using some other method of getting the
stud out? I was thinking I'd get the engine on its side, flood the
region with penetrating spray, let it soak, drill the hole and use a
wide enough screwdriver to get the stud to move. This worked well with
some stuck bolts on my alternator. Just jammed the screwdriver into the
pilot hole and it gripped and turned the bolt out.

Made me wonder what I paid the mechanic for!
