I've used AC or Fram.

From the air intake to valve cover: fresh air inlet for the CCV system.

Borla quit making headers, so you'll have to find another brand. It's been on there over 20 years, so I don't really remember if it felt different. IIRC, the factory pipe went down to 2 in or less under the trans.

The biggest choke point is the crossover pipe under the transmission if you still have the OEM one. YJs were rated 10 HP less than Cherokees due to this. My Borla header included a full size cross over pipe.

10w-30, 5w-30, 5w-40, 10w-40 etc will be fine. I run 0w-40 M1 Euro in mine. A 40w will have more ZDDP for the cam than a 30 as the EPA limits it in 30W and below to save the cats...

Probably the oil rings.

It's probably the valve seals if it smokes mostly at hot idle, but not driving down the rd. Mine doesn't smoke at all on the rd, but if it's hot and I just let it idle for several minutes, you can see some smoke. Also, if it smokes briefly immediately on start up, as that is oil that ran down...

Possibly. If you don't have just one oily plug, hard to know.

No, the valves are closed on compression. The valve stem seals are just rubber and prevent oil from leaking down the stems. My 92 needs them replaced, they are original. Can smell oil burning at idle (high vacuum), when the oil is hot and thin.

Could also be the valve stem oil seals.

Check the fuel pressure. But when my pump was weak, it was like hitting a rev limiter when running through the gears. I'm thinking plugged cat.

Turbo mufflers are similar to factory, but are built with less internal resistance. Usually shorter paths, larger tubes, more places for pressure to shortcut the path. Dynomax: The Banks is a straight through design. You can look through it.

I've had the Dynomax Super Turbo on my 92 forever. It's not stainless, so maybe not the best for IL. With the soft top, 3.55s, and 30s, you can hear the exh up until the point the wind noise takes over. :ROFLMAO: Mellow low tone at idle. Great burble on decel. I've got a stainless Banks...

Fuel pressure regulator leaking gas.
