finding the manifold crack

["John C. Gottstein" <gottstein@erols.com>]

Hi,
  After getting a lot of suggestions from the list on how to fix the crack
in my manifold, I'm going to try MarinTex, a super strong epoxy that says
that it will withstand engine temperatures.  Now the problem is, I can't
find the crack (someone else discovered the crack and told me about it).  Is
there a way to find it, like maybe it will be blowing a lot of exhaust out
of the wrong place?

I wouldn't be so obsessive about this whole manifold crack thing, but it's
gotten really LOUD.

Thanks a lot,

John
