    Detonation - 01 Disco

    OK. Its detonation. If I put colder plugs in it almost goes away. Still there just less severe. Its not a cat, or an exhaust leak. I don't have heats shields, those rusted away at 280k. Same for the starter heat shield. I am not a master tech but I know what detonation sounds like. What...

    Detonation - 01 Disco

    So knock sensors, when I tested them they did spike in voltage when I would tap them when hooked up to my meter (that was my "they are doing something" observation) at $63 for two, I ordered the knock sensors, at 312,000 miles I think I am due anyway and can rule that out. The biggest...

    Detonation - 01 Disco

    Good points - so I took the knock sensors off and tested them with a meter, they are doing something. If that something is what they should be doing, I don't know it seems they are hard to test. I have gotten mixed feedback from techs on if an unplugged knock sensor will throw a code or not -...

    Detonation - 01 Disco

    Thanks for the replies. After 2 indie mechanics and a trip to the dealer (with some seasoned techs) everyone is stumped. No codes, no running issues, lots of power, great gas mileage (350-375) per tank, no other obvious issues, knock sensors working, no MAF issues. Had an upper engine intake...

    Leaking Roof

    The headliner is not that difficult to remove - in order to follow the water trail (which can head in a multitude of directions) much like trying to trace a leak from the top of the motor to the bottom, the headliner needs to be removed, all A-pillar trim, B-pillar etc. Then turn on the...

    Detonation - 01 Disco

    01 Disco - been trying to resolve this for some time. Pinging and detonation (sounds like drivers side) marbles when accelerating, worse when warm out. No noise at idle or revving. I replaced a number of accessories thinking that might be the culprit. I use 92/93 octane. Have never heard...

    A/C Compressor - Repair, replace...?

    01 DII - Have determined bearing noise is coming from the A/C compressor pulley. A/C works fine, clutch engages etc. Is there a kit to replace just the pulley and bearing assembly? Or is it a whole compressor replacement? In looking at new compressors - $269 from BP Utah is not bad, but...

    Tracking down a tick when cold and put in gear..

    I have had the cat deal - doesn't sound like that. Very rhythmic tick...only in gear and moving and when cold - like 2-3 minutes it stops. Forward and reverse...does not do it in neutral when revving the motor. So flex plate - how to diagnose and what to look for? If it is the flex plate...

    Tracking down a tick when cold and put in gear..

    Folks - stumped on this one 01 Disco 310k miles, ticking/clicking when cold and first put in gear...ticks for the first half mile and goes away when warm and then does not resurface. Does not do it in park, and revving engine does not make sound only when put in gear and moving. Changed all...

    Can't Get Air Out of Heater Core / Considering Vacuum Kit

    I think you will find there is no real rhyme or reason or specific method for getting the air out of the system - everything mentioned will work, it just needs to be done over a couple of full warm up and cool down cycles. I had similar issues but after replacing the reservoir and cap with OEM...

    Exhuast Gaskets DII Proper Orientation

    Does anyone know the proper orientation so they don't leak - I was reading an article (engine rebuilding site) which I cannot find now that illustrated the proper way they go on - both for manifold and y pipe since one side has raised indents. Thanks -
