FOT,

I have one thought to add to the sealant conversation and I am not =
intending to restart the entire oil debate by commenting on this.   I =
know that many on the list feel that Brad Penn is the only oil, and that =
is OK if that is your belief.

However, there are many good race oil choices on the market and more =
being added every day.  Some of the synthetic and synthetic blend race =
oils have an additive package in them that is very aggressive to some of =
the traditional sealants.  They will actually dissolve them even after =
they are cured.

My tought here -  if you have interest in trying a particular oil you =
should check with the oil manufacturers tech support regarding sealant =
compatibility.  Do 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.

Paul Ricco

Clean it up good and then use your sealant of choice.
