I don't know what engine you have, but Continental says 'thou shalt not use
permatex'.

When you squeeze parts together with liquid gasket material, some of the
excess material goes out (where it can be wiped off), and some of it goes
inside (where it can't be wiped off). If this material breaks loose and
finds its way to an oil passage, you will end up with "less than optimum"
lubrication.

Assuming you have a Continental engine, look for  Continental SIL99-2B,
http://www.tcmlink.com/pdf2/SIL99-2B.pdf. This specifies the various
sealants and lubricants recommended for Continental engines.  If some other
manufacturer, they will have an equivalent document. You can also call their
support line and ask them.

Continental 800-326-0089
Lycoming 800-259-3279

Good luck,

I've got some oil leaking around the mag hole cover plates.
Permatex Aviation form-a-gasket was used originally as the sealant.
Anybody got a better solution?

Thanks,
