Thanks Mike for the information,
I was using Fram filters and the lifters would clatter on hot or cold
start 
ups. I now use AC Delco or Mobile One filters.  The lifters still clatter 
but only on cold starts and they
quiet down after a couple of seconds. I figure if they clatter at all this

can't be good and it will just get worse so that's why I thought that they

should be replaced.

I also suspect it could have a bad head gasket. It's using about a quart
of 
anti- freeze a month. There are no obvious leaks and I can't figure out 
where else the anti-freeze is going. There are no other clues of a bad
head 
gasket.
We bought the Jeep new so I know that it has never over heated which makes

it hard to believe that the head gasket could be bad.
But where else could the anti-freeze be going except out the exhaust. 
Recently got a check engine light saying the cat. converter was bad.
 I understand that coolant in the exhaust can cause the converters to fail

prematurely.
If it is burning coolant then I need to get it fixed before it destroys 
another catalytic converter. This vehicle only has 70,000 miles on it. 
Shouldn't be having these problems.
Any thoughts or guidance would be appreciated. ( Please don't say buy a 
Ford, my wife loves her Jeep)

Thanks again,
Dennis
