      The parts needed depends on how many parts (or how few) are supplied with the new engine. Is the new engine a used one or remanufactured?

      Typically, these parts are needed; belts, hoses, vacuum hoses, engine mounts, filters; oil, fuel and air.

      Free - if the labor is all yours to perform the work. Reference the 'How-To-Guides' on the AutoMD website for the specific steps to replace the spark plugs. Also,this website;

      Be warned, very few repair shops will allow the customer to supply the parts upfront. Most shops will turn away this work.

    My vehicle starts sometimes and then it runs rough for a while and settles out, after that it runs great on the highway.
    The problem is when i turn it off and try to restart it after about 15 min. it will not start. I was told that the fuel pump was bad so I replaced it but I am having the same problem

    Could it be a the clutch fan in my Disco that is causing a loud noise?
    We replaced the water pump in July 2014, the rover seemed to be running better, now all of a sudden there is a terribly loud sound coming from under the hood in the front of the engine bay. It almost sounds like a loud lawn mower, not a ticking sound. It gets ...

    Engine pecking after engine gets hot
    I have a peck that starts in engine after it runs about 15 mins and gets the oil hot. It sounds like its coming from the driver side upper part of engine.It had this peck and we went and rebuilt the engine and its still got the peck.Any ideas of what it could be???
    • Jimm
      9/28/2014 Jimm
      Please describe this 'peck' - is this a click or tick sound? If yes, there are several possibilities; collapsed hydraulic lifter, worn engine valve, worn lifter, worn camshaft.

      What parts were replaced during the rebuild? How extensive was the rebuild? How many miles since the rebuild?
      9/28/2014 dirt
      It has a new cam and lifters.rings , bearings, oil pump, It has no miles on it. It sounds great when cold and after 15 mins or so after the engine gets up to temp it gets a loud peck that sounds like coming from driver side but still runs smooth.
    • Jimm
      9/28/2014 Jimm
      Were the valves adjusted for proper clearance when the engine was cold - just after the rebuild? There is a specific valve adjustment sequence for both the intake and exhaust valves and the camshaft lobe position - to achieve the cold clearances required, so that when warmed at operating temperature - the valves and upper engine components are quiet and will wear correctly.

      do you know those clearances??

      sounds like its flooding,have you checked your pcv valve?crank case ventilation through the valve cover ,as far as the thump sound,the only thing i can think of would be your starter selonoid,maybe a loose connection,hope this helps.

    Possible fix
    Misfire causing excess emissions

      Retrieve any codes that are stored in the computer and report them here. Alternatively , you can search that code on google and see what may be causing it.

      Ignition misfire may be caused by the following:
      Fouled spark plugs
      Faulty spark plug cable
      Faulty ignition coil/coil pack
      Faulty ignition control module
      Faulty rotor/distributor cap assembly
      Burned exhaust valve (in which case you would likely have backfire)
      Clogged/faulty fuel injector
      Worn piston rings (low compression)
      Blown head gasket or warped cylinder head
      Cracked engine block
      Cracked piston
      Bent pushrod
      Loose rocker arm
      Collapsed hydraulic lifter
      Worn valve springs

      These are only some of the possibilities. I've lists the most common causes of misfire (concerning a single cylinder)

    I haven't started my vehicle in 2 yrs, and dmv requires a smog certificate. What should I do to begin this process?
    Charge battery? Reboot the computer system? (Hand held code reader) Add a liquid into the gas line? Run vehicle for a half day?

      Charge battery or replace to be safe if it ran good before you let it sit then its still a good car get some fuel treatment to clean old gas depending on your fuel system its mite start up with a little pumping on the gas turn the key all the way but not to start just to get the fuel pump ready on and off a few times then start or you may need a can of starter fluid, the vehicle computer will program itself after you drive around for 30mins-1 hour good luck

      I failed smog test because of the moniters.
      Two (moniter readings) never booted/responded for reading, though my LR passed
      All the emissions. The AAA service jump started the vehicle but didn't charge the battery.
      So I was forced to drive around for the alternator.

      Here are the codes (p1536 & pO560) SYSTEM voltage?
      Dmv will not give me a registration until i pass smog,
      and it will not pass until the moniter reads correctly.
      Now im in for an interesting process of events...huh?
      slow rider
      4/14/2014 slow rider
      the battery mite be dead it mite be the issue for the code P0560
      P0560 - System Voltage Malfunction

      Possible causes

      - Loose or missing alternator drive belt
      - Faulty alternator
      - Battery defective
      - Open or short system voltage circuit
      and the other code p1536 mite be your Parking Brake Switch

      So check batt for full charge.
      Check the alternater belt drive for firm fit?
      Basically... just take it to the mechanic, or have one check for these issues?

      4/15/2014 slow rider
      you may need to let your computer program more and boot all systems some cars take longer then others a obd2 is a good tool to know when systems are ready I don't think the codes failed emissions ,if you have a fair mechanic and want to fix the code issue sure they should be really minor if you can't check the Possible causes your self tell them to check them ,also next time you go to do the test ask them if they can check if your systems are ready

    Vehicle fails to retain charge, discharging a fully charged battery within a hour. Occurs about every two weeks.
    Mileage 80K. Occurs in hot or cold. No faults found by dealers. Usually preceded by proximity sensors not working/coming on at random.

      You may have an intermitent draw on the battery. I can't imagine why the dealer can't find anything.
      Did you mention the proximity sensors coming on at random?

      You'll have to be more specific. Do you mean when you turn the key to start it does nothing?
      Or is the engine cranking over well and not starting? Let me know and I can help you better.
