Using Oil Already? Help!
 

I have a 99 TJ SE (read: 2.5L), 5spd, with about 66k miles on the odometer.
It's been about 3 months since my last oil change, although only about 2000
miles, if that. I checked my oil and noticed I'm about a half-quart low.
Obviously, something is wrong here.

I noticed a few months back I have a small... drip... at the bottom of the
oil pan on the back side. It isn't enough to drip on the ground, but the oil
collects there. I'm guessing rear main seal. You have to actually touch it
to get the oil to "drip". I read on here someone else had a similar leak and
let it go for quite a long time. Could that be the source of my 1/2 quart of
missing oil? I don't seem to have any other leaks. Although my transfer case
seems to be... wet... don't know how else to explain that. I'm guessing
that's from the oil blowing back when going down the road.

A couple of things to note:

- Been getting a rough idle every now and again as of late (plugs, wires,
cap, and rotor replaced at 45k miles. Cat-back and new, stock, cat converter
installed at about 50k miles)
- When I start it, I get a "pop" from the exhaust. This has just recently
started. Sounds like the exhaust is plugged, and something "pops out" as
soon as it fires. Almost sounds like something is hitting the underside of
the tub.
- Been doing a lot more highway driving over the last 6 - 8 weeks than
usual.

That's all I can think of. Any thoughts?!?

Check the back of the valve cover it is usually the problem and 1/2 quart in
2k is not bad.

That's no oil between oil changes as far as I'm concerned.

Yeah, my Suburban was blowing a quart every three hundred miles. I put two
aftermarket vent caps on each valve cover, connected to three quarter inch
heater hose, just to keep the oil spray off my windshield. This is nothing.
