[urq] Re: Exhaust manifolds

[JShadzi at aol.com]

I have seen quite a few with the only crack being underneath the collector,
including the one I just took off my car.

 I've never seen a one-piece manifold cracked in only one place.  Every
 one I've seen has been cracked in two places, and it's always the same
 two places.  The configuration and loads on the thing make me happy
 that the front crack is a direct and immediate result of engine mount
 failure - but I wonder on occasons about the back one.
