    P0432—is there any way to get rid of this code without replacing the cat

    I have had to tighten mine several times. 2006 Rubi with 245,000 mi, original owner. I still have the original cats on mine. When it throws those codes, I crawl under and tighten the bolts. I meant your tailpipe emissions. If you have emissions testing where you are, you will fail. You...

    P0432—is there any way to get rid of this code without replacing the cat

    1st be sure the cat to manifold bolts are tight. An air leak there will lead to P0431 and 432. If the cats not melted and restricting flow, all it means is your exhaust is dirtier than it should be. How many miles on it? Yep, converter prices are through the roof right now.

    Were any of the strands cut? I couldn't tell. If it's just the insulation, I would just tape it or coat it.

    Proper break-in for new rocker arms and pushrods?

    It's critical for cam/lifters and you need break in oil for them, probably not for rocker arms.

    I would use liquid electrical tape.

    2006 4.0 has no crank, no start, and no power to starter

    Here's the schematic. FSMs are available under resources. Yeah, this is what I was remembering, PCM is involved in starting which complicates things.

    Nice. I put new split loom on mine as it all crumbled.

    Check all the wires; around the dipstick, back of the head in particular.

    Based on those pics, your cam gear should be OK.

    2006 4.0 has no crank, no start, and no power to starter

    I seem to recall some oddity with the 05 and 06 key having to be in the start, not on, position even if you jump the starter for it to fire. If you have a helper, worth a shot. Check the ignition actuator pin. Common failure point. It can be started with a screwdriver if the actuator pin...

    2005 with P0344 issue

    The contact points should be smooth and shiny on the OPDA gear and the cam gear. Not this:

    Pull the OPDA and inspect the cam gear through the hole.

    Help Diagnosing Engine Knock

    I think they should all be at the same height. If that is the only one at that height, I would guess burned valve or seat which means the head will have to be pulled.

    Check the wires first. Also, keep the OEM sensor, as they are the best. If the cam gear is shot, you are looking at replacing the cam and lifters.

    Help Diagnosing Engine Knock

    He's removed the pushrods and rocker arms, so not connected to the cam.

    Who rotates the spare tire?

    If they all match, yes. But at times I have simply put the best old tire on the tailgate when buying 4 new ones of a different style and of course didn't rotate it in the mix.

    Locker Wiring Mess

    Wow! Some people. You can pull up the wiring schematics in the FSM under the Resources section on this site.

    Hard bucking when accelerating, cutouts at high RPM (parked on side of interstate)

    I think there was a run of the Bosch assembly recently, but they may all be gone.

    High Elevation Gear Ratio - 33's - 6-Speed (NSG370)

    For '06 the 4.0 specs are: 190 HP at 4600 235 ft lbs at 3200 Note that 3200 is straight up on the tach. My 92 Jeep tach is straight up at it's torque peak as well. It will be fine running 3100 to 3300 all day long and you will be at or near the tq peak.

    Normal Oil Pressure for 4.0

    Yeah, that's my thoughts exactly. I have seen some folks put in a tee so that they can keep the PCM happy with the switch and run a real gauge. I haven't done mine yet.
