It was exactly what happened that I was so careful to avoiding
happening! Anyway I will drive the 140 diesel for a few days until I
can figure out the next thing to try. I still think I might try just
using that unused adjoining hole in the head.

I pulled my 98 e300 in the shop yesterday for what was supposed to be
a simple belt shock replacment. I knew the hole was stripped out so I
already had the proper size helicoil on hand. I drilled out the hole,
tapped it and inserted the helicoil. Put it all back together and
after running a few minutes the damn shock popped of the rubber
mounting. This was a stabilus from autohaus az but not the dealer
part which j guess is supposed to be better even though it is made by
stabilus. So I took the bolt back out and the helicoil came out with
the bolt. So I drilled it again, tapped and put new coil in. For some
reason bolt was somewhat hard to turn then snapped off all the sudden
flush with the head. Great. So I pull the radiator. Spend all morning
drilling on the bolt. At one point broke off a drill bit in the hole
but managed to get it out. Finally get it drilled out enough to then
drill the final hole size for the helicoil tap. Do that. Install
another coil and for some reason even though the hole was drilled and
tapped and the coil is the right size the bolt will not thread in,
it's like the hole is just slightly too small. So I pull the coil
out, drilled again, tapped again, ran it down and all the sudden the
tap breaks! When it does the only thing I can figure is the other
price shot off the wrench and the punctured the condenser, I start
rapidly losing the entire ac charge. So at this point the car is
screwed. Now needs a new condenser also. How the heck am I going to
get this hardened tap out of the hole? There is another slightly
smaller hole right next to the shock hole, I wonder if I can just
bolt it to that hole? I am concerned with it rattling though since
the bolt is slightly smaller. This is a nightmare. There is nothing
further I can do with this car at the moment until I figure out how
to extract this tap and get a new condenser here. I guess I should
now start on the glow plug project for my 97 but I suspect it's got
dorm fuel leaks that need to be replaced while its apart and I don't
have the parts for it.

Wow! that is bad.
I have a 240D I'd part with for a ridiculously high offer!
Maybe you should drive that nice 124 300D.
