Water jacket plugs

[alfacybersite <acs@xxxxxxxxxxxxxxxxx>]

There has been a thread going on the 750-101 Digest regarding the same
problem. In this case, it is one of the plugs in the back of the head.

The fellow tried to remove it and it stuck after about a half turn.
Previously a suggestion had been put forth to use a special Loctite
sealer which will actually work it's way around the threads - even go
uphill. It was added if access is difficult (which it would be in this
case) to use a a piece of wire (or?) and let the sealant flow down onto
the threads.

I've never had any luck removing these plugs. I believe the aluminum in
aluminum much prefers to gall, rather than unscrew.

One other place to look for a water leak before 'fixing' the plug is to
check if any coolant is leaking out from under a nearby head stud nut,
then pooling around the plug.
