    Muffler removal

    I would try to use heavy wire and exhaust clamps to "refasten" the broken parts together so that most of the exhaust blows into the muffler.

    A/C compressor leaking oil from center of compressor body ?

    Under some conditions, during normal A/C operation, condensation might form at the end of the compressor, causing exterior corrosion after years of good A/C performance. I've seen frost on plenty of suction lines...but I can't remember a time that I saw frost (or unexpected condensation) on any...

    Nickb2....just wanted to say I totally enjoyed that video "Green River". Thank you for posting it.

    So ... Test 1, Passed................................Test 2, Failed....But not a total failure, just not "up to specs". ........................Test 3, Failed.....But not a total failure, just not "up to specs". I say, "Two strikes, You're Out."and that getting a new coil is well worth a try.

    A/C compressor leaking oil from center of compressor body ?

    If the leak is at the bottom of the compressor, and oil "rests at the bottom" on the inside of the compressor, oil might leak out without refrigerant loss. Example...straw in a drinking cup...if you blow into the straw, no air bubbles in the water UNTIL you have pushed the water out of the...

    A/C compressor leaking oil from center of compressor body ?

    Pressure in an aerosol can is able to push in dye when low side pressure is low enough (engine running, AC turned on, compressor turning).

    Also...look back at my reply #8...I added some more info.

    A/C compressor leaking oil from center of compressor body ?

    Yes, the compressor body is kind of like a sandwich. The oil would be like Mayo squirting out between the meat and the bun. Does your AC system have dye in it? If it does, then the oil may be engine oil leaking form the front edge of the valve cover. What color is your antifreeze? Sometimes...

    This schematic is JUST AN EXAMPLE if you are asking about tests you can do to see if the coil has failed internally or is not getting the power it needs to operate. There are voltage and ohms tests that can be done.

    no spark issue

    If you have a good knowledge of how electricity works (and I guess you don't) you could get the job done with a jumper cable with well-insulated handles. This could be pretty simple, actually. Clamp one end of a cable to engine metal, hold other end 1/8" from coil "post" and crank engine (gonna...

    no spark issue

    Special pliers like this can perform the same test by using them to hold a spark plug wire (or coil wire) close (about 1/8th") to a metal (grounded) part of the engine and look for spark. Then slowly move wire farther away from engine to see how far the spark will jump. Disclaimer: this is...

    no spark issue

    One of these will test A. Is it working? and B. how "strong" is the spark? Turning the red knob increases the gap that the spark must jump...a healthy coil (and related components) will be able to jump a gap about 3/4" wide.

    Happy holidays

    Today is a rare day for me. I'm enjoying the second half of a two day vacation. Yesterday was very productive. I replaced our front door knob with a shiny new "lever-style" opener. It was quite a challenge to re-key the lock to work with my old key. It looks and work's great! Goodbye crusty old...

    1998 5.9limited 46re howling like a b!tch only when accelerating or holding throttle steady...... ????

    My suggested test would be most meaningful if the result was "Transmission/Transfer makes a bad noise." If there was no bad noise heard, you have consider the fact that rotating parts were spinning, but there was no load on those parts. So, a bearing problem might not be noticeable (got...

    Another variation of this test would be to start engine, quickly shift to Low, and then you can control the upshift by moving shifter to 2, 3, D.

    1998 5.9limited 46re howling like a b!tch only when accelerating or holding throttle steady...... ????

    I suppose you have listened for transmission noise if you put transmission in "D" with transfer case in neutral? I would expect that at idle speed, trans would shift up through each gear. CAUTION!! Shut off key to stop test and let engine and drivetrain parts stop rotating and come to a...

    That's a big Jeep. Is it 4WD? AWD? Some kind of suspension lift? If so, a transfer case, driveshaft, u-joint, or mount could be the source of the noise. I'll bet your tires make a different noise.

    I was a Dodge/Jeep mastertech in 1998- 2001. Lots of noisy rear differentials in Grand Cherokee during those years. Many were still under warranty.

    FIXED! P0455 - 2017 Honda Pilot, 60k miles

    Those slots may be normal. I think this pic shows replacement parts.
