Re: Gasket Questions
Ok. That does not fall into the category of the engines I was talking
about. There should be no knock with your TJ. If it sounds internal to
the engine, try taking a piece of garden hose and using it as a
stethoscope to try and determine where in the engine the knock is coming
from.

Re: Gasket Questions
Ok. That does not fall into the category of the engines I was talking
about. There should be no knock with your TJ. If it sounds internal to
the engine, try taking a piece of garden hose and using it as a
stethoscope to try and determine where in the engine the knock is coming
from.

about. There should be no knock with your TJ. If it sounds internal to
the engine, try taking a piece of garden hose and using it as a
stethoscope to try and determine where in the engine the knock is coming
from.

Re: Gasket Questions
Will do if I ever get a chance. The trouble being the intermittent nature of
the problem. It won't do it if I'm ready for it with a stethoscope in hand
or mechanic nearby. It's usually a stoplight at a busy intersection or
something like that where it crops up.

something like that where it crops up.
