Subject:Re: Heli-Coil an Engine Oil Drain?

Folks,

Firs of all thank you to all that responded.  I
enjoyed all he comments from the kind to the pithy.
Regarding the "poor bastard" comment - no worries  I
took that as it was intended.

So any rate, to the task.  After reading the comments
I ended up taking Mr. Ricardo's advice and it seems to
be working just fine.  The bolt I bought at the FLAPS
was a self tapping type so I plan to replace it with a
regular bolt at the next the next oil change to
minimize the chance of cross-threading.

You folks are a great resource.

Barry
