    What oil should I use?

    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...

    Burning oil

    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...

    Burning oil

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

    Burning oil

    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.

    94 Jeep YJ Check Engine Light Issues

    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.

    1992 Jeep Wrangler YJ 4.0 (Manual) – Exhaust Recommendations

    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.

    1992 Jeep Wrangler YJ 4.0 (Manual) – Exhaust Recommendations

    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...

    Spark plug gap after performance coil

    I had one on my 92 when I was having coil issues. Chinese junk just like the store brands and the new MOPARs. Only one that has lasted is the Blue Streak by Standard Ign, made in Poland.

    Code 27: injector circuit malfunction (what would you do?)

    Nobody ever wants to test/inspect the wiring... You're gonna have to inspect the injector wiring for chaffing.

    Stock windshield wiper size?

    They are all GM columns. You'll need a wiper switch with the delay.
