Great point, Paul; As both Dave and I have said in other threads, the Drive=
n/Joe Gibbs oil we use dissolves the Permatex Aviation cement popular for r=
ear main cap side seals and some have indicated they use on the fo8 gaskets=
.

FOT,
I have one thought to add to the sealant conversation and I am not intendin=
g to restart the entire oil debate by commenting on this. =C2=A0 I know tha=
t many on the list feel that Brad Penn is the only oil, and that is OK if t=
hat is your belief.
However, there are many good race oil choices on the market and more being =
added every day. =C2=A0Some of the synthetic and synthetic blend race oils =
have an additive package in them that is very aggressive to some of the tra=
ditional sealants. =C2=A0They will actually dissolve them even after they a=
re cured.
My tought here - =C2=A0if you have interest in trying a particular oil you =
should check with the oil manufacturers tech support regarding sealant comp=
atibility. =C2=A0Do some homework upfront and it will save you from having =
to tear down a fresh engine to re-seal your rear main gasket, oil pan, etc,=
etc.
Just my two-sense on the sealant subject.
