No, don't use heavier oil. The drip you see is probably part of the 1/2
quart lost. But 1/2 quart between oil changes is not bad at all. You say
you have 66K, tuned at 45K. Your due for plugs again, right. That may cure
your start-up noise. Your engine should last many more miles and I do not
think you have any internal problems.

Definitely check along the back of your engine for oil. If you have
any, it is very likely valve cover. As for the oil itself, you might
want to move to a 20-40 or a synth blend of 10-50. Or drop half a can
of STP in the thing.

Because the leak is also evident covering the t-case, I would suspect
you have blown the valve cover seal. It only leaks when running, the
faster , the more potential for leak. I would take a clean rag and run
it across the rear of the engine head just below the valve cover to see
if there is oil there.

Most of the automakers say that 1 quart per 1000 miles is 'acceptable'. I
don't know if I would agree with that but that is another matter.

More telling is that the oil loss is a recent change. but it is still more
likely that your engine is leaking/seeping oil than burning it.

Carefully check the back of the engine head to see if there is fresh oil
that could be leaking from the valve cover. This is most often the source
of Jeep oil leaks.

It wouldn't hurt my feelings any if you went to a 15w-40 or 20w-50 oil but I
think it more likely you will find a leak

As for the rough running, etc, I see it has been 22K miles since your last
tune-up. While this may be considered 'low mileage' it wouldn't hurt to
throw in a can of a good quality fuel injector cleaner and consider new
spark plugs.

I am not sure about the 'pop' you are hearing. It could be raw gas igniting
in the catalyst or muffler or perhaps an exhaust leak. Have you changed
where you buy your gasoline?
