Greetings, Fellow Listers,
Thanks again to The Lists! Based on suggestions from all of you, I did a
little more investigating of my exhaust leak. First, I tried disconnecting
one plug wire at a time to see if things changed. When I pulled the #3
wire, the noise stopped. None of the other wires affected the noise. Next,
using the old "rubber hose as a stethoscope" trick, I was able to find the
noise at the bottom of the manifold gasket right under the #3 pipe. I also
checked at the collector to see if there may have been a crack there - no
noise. This morning I pulled the manifolds off the car. The gasket showed
a black (carbon?) strip across the face of the gasket right under the #3
port. Looks like a leaking gasket to me! A new one is on the way. With
luck, Lazarus will be purring once again before the weekend.
Anyone care to venture a guess as to why the gasket decided to leak?
