Re: Cap'n, #5 is down, 'n I can't hold 'er any longer!

Another thing that I've experienced on my old n/a 5ks was the fact that
when the head gasket blows, you'll also end up kissing your 5th cylinder
exhaust manifold gasket goodbye. The exhaust is very hot in comparison to
the coolant. Head gasket blows, coolant that is (relatively) cooler rushes
in and out of cylinder. Thermal shock cracks em gasket's metal backing.  
That's what that notorious clicking noise I hear on soooo many other
Audi's is.
