  • ekati Jun 17, 2008

    is the engine in the plymouth reliant a 2.2 or 2.5 or did it come in both sizes

  • ekati Jun 17, 2008

Questions No. 1 : will the engine be damaged if the timing belt fails when the engine is idling?

Answer: YES

Nothing could be damage at this point of time BUT if "timing belt fails" as what you've mentioned earlier during idle, it could affect your machine's integrity.

As always engine components must be kept in precise synchronization.Timing belt failure may result in serious engine damage, and can cause an engine to stop running altogether.
This results in loss of engine performance.

As what we all know , replacing timing belt is laborious as it could affect other vital components.

Keep us posted ....

Cheers.

Http://en.wikipedia.org/wiki/Timing_belt
Depending on the design of the engine, the piston and valve paths may "interfere" with one another and incorrect timing in their movements may result in the piston and valves colliding. (Such designs are also called "interference head" or "interference engines", and include virtually all diesel engines. Conversely, non-interfering engines, such as the Mazda B engine, are called "free-wheeling" or "non-interference" engines.)
In interference designs, regular service is especially important as incorrect timing may result in the pistons and valves colliding and causing extensive engine damage and therefore costly repairs. The piston will likely bend the valves or if a piece of valve or piston is broken off within the cylinder, the broken piece may cause severe damage within the cylinder, often also affecting the crankshaft. Some manufacturers, such as Nissan, have switched back to timing chains for the majority of their engines because of the breakage problems associated with belts. However, in some newer engines, timing belts are designed to last the effective life of the engine. Other manufacturers, such as Toyota, use a mix: timing chains on their interference engines and timing belts on their non-interference engines. ..............

Is it an interference type engine, if so it probably will. If it has variable cam timing, then the is an less of a chance to damage it while idling.

    and this model is non interference by design, so it will not be damaged.



  • Graeme Ross
    Graeme Ross Jun 17, 2008

    I got this from here.


    Chrysler upsized the K-car engine in 1986, increasing the displacement to 2.5 L and adding counterrotating balance shafts
    to smooth out the vibrations and harsh harmonics normally produced by
    long-stroke 4-cylinder engines. The increased displacement came from a
    raised deck and longer 104 mm stroke, making the 2.5 engine very undersquare and tuned for low-end torque rather than high-RPM power.

    This is why your engine is non interference because of the increased deck.


  • Graeme Ross
    Graeme Ross Jun 17, 2008

    again from the link I gave you.

    The 2.2 L straight-4 engine developed by Chrysler for the K-cars is sometimes referred to as the 'K-car engine'. After its debut in 1981, it became the basis for all Chrysler-developed 4-cylinder engines until the Chrysler Neon engine was released in 1995.

    The 2.2 was a homegrown replacement for the 1.7 L Volkswagen engine Chrysler had initially used in its Omni and Horizon
    models. Many of the features of the 2.2 are based on the company's
    experience with the Volkswagen engine, including the aluminum head/iron
    block design, the SOHC design with in-line valves, the offset water pump, and the location of both the intake and exhaust manifolds on the rear of the engine.

    To reduce overall length, it is a "siamesed" engine: there are no
    coolant passages between cylinders. The bore spacing is a tight
    87.5 mm, limiting the potential for increased bore diameter.

    All 2.2 blocks were made of cast iron and used a timing belt rather than a chain, but they are non-interference engines. The earliest used a two-barrel carburetor, but fuel injection was phased in starting in 1984 on turbocharged models, and 1985 on normally-aspirated models.

    you will note the 4th last line.


  • Graeme Ross
    Graeme Ross Jun 17, 2008

    Both the 2.2 and the 2.5 dirivitive are non interference, yet I note that you have accepted Ekse solution.

  • Graeme Ross
    Graeme Ross Jun 17, 2008


    there is a great writeup here on the 2.2/2.5l motor, and again they quote Pete Hagenbuch, the guy that designed the engine the engine is non interference

    .....One of the engineers explained: "I always hated belts, but the weight penalty
    for chains was as big a factor as cost." Oil sealing was also a factor. 2.2
    liter engines are all noninterference designs, so they generally are not damaged
    when the timing belt breaks.....

    Sorry to keep pestering you about it, but the truth gotta get through...

    A timing belt failure can be disastrous for an engine that doesn’t have enough clearance to prevent the pistons from smashing into the valves if the cam stops turning. When such a collision occurs, it usually results in bent or broken valves, and sometimes even a shattered piston. What would have been a couple hundred dollar job to replace the timing belt now becomes a major repair expense. At the very least, the cylinder head will have to be removed so the damaged valves can be replaced. If the head has additional damage (like damaged seats, guides or combustion chambers), further head repairs or replacement will be necessary. And if an open valve took out a piston? An overhaul or engine replacement may be required.

    The damage can be really bad.

    It's also possible for nothing to be damaged at all.
    In your motor, timing is everything. That’s why your timing chain
    and/or timing belt are so vital to the operation of your entire
    vehicle. You see, without a properly installed and adjusted timing
    chain or timing belt, the valves on your engine don’t open and close at
    the appropriate times. A sloppy timing chain can result in poor
    running, valve clatter, and loss of power, while a broken timing belt
    can cause your engine to stop running or, on an interference
    application, cause your valves to crash into your pistons. If that
    sounds expensive to you, you’re right. If a broken timing belt can
    cause so much damage, why doesn’t everyone use a timing chain? For all
    its advantages, a timing chain is noisier, less efficient, and more
    expensive than a timing belt. These timing belt / timing chain
    comparisons are particularly relevant on the overhead cam engines that
    are so common these days. Since an OHC timing chain would be so long, a
    timing belt actually has less lash and stretch resulting in better
    camshaft timing and improved efficiency. So don’t think that, just
    because your manufacturer specified a timing belt for your favorite
    ride, they’re looking forward to the day they can supply you with a
    remanufactured engine. In many cases, a timing belt makes more sense
    than a timing chain. While a timing chain may last the life of an
    engine, a timing belt has specific requirements for replacement
    intervals. Check your owner’s manual for timing belt replacement
    mileage and follow those requirements to the T. If you have a timing
    chain instead of a timing belt, signs that your timing chain may need
    replacement include loss of power and noise from the timing cover at
    the front of your engine. Unlike the timing belt crowd, you probably
    won’t destroy your engine by running with a worn out timing chain. You
    might get run over by a semi on the interstate, however, trying to
    accelerate with that clapped out engine and its stretched timing chain!
    Keep me posted,
    Nathan

    Edit: if the engine is running at all and the timing belt snaps it is possible for something else to get damaged.

How to change a timming belt on honda civic


Timing Belt and Tensioner REMOVAL & INSTALLATION 1984–87 Engines
  1. Turn the crankshaft pulley until it is at Top Dead Center.
  2. Remove the pulley belt, water pump pulley, crankshaft pulley, and timing gear cover. Mark the direction of timing belt rotation.
  3. Loosen, but do not remove, the tensioner adjusting bolt and pivot bolt.
  4. Slide the timing belt off of the camshaft timing gear and the crankshaft pulley gear and remove it from the engine.
  5. To remove the camshaft timing gear pulley, first remove the center bolt and then remove the pulley with a pulley remover or a brass hammer. This can be accomplished by simply removing the timing belt upper cover, loosening the tensioner bolts, and sliding the timing belt off of the gear to expose the gear for removal. NOTE: If you remove the timing gear with the timing belt cover in place, be sure not to let the woodruff key fall inside the timing cover when removing the gear from the camshaft. Inspect the timing belt. Replace if over 90,000 miles old, if oil soaked (find source of oil leak also), or if worn on leading edges of belt teeth. Fig. 1: Timing belt and front cover assembly — 1984–87 engines 86833161.gif
    Fig. 2: Positioning the crankshaft and camshaft pulleys before installing the timing belt — 1984–87 engines 86833162.gif
    Fig. 3: Timing belt tension adjustment — 1984–87 engines 86833163.gif
    To install:
  6. Be sure to install the crankshaft pulley and the camshaft timing gear pulley in the top dead center position. Align the marks on the camshaft timing gear so they are parallel with the top of the cylinder head and the woodruff key is facing up. NOTE: When installing the timing belt, do not allow oil to come in contact with the belt. Oil will cause the rubber to swell. Be careful not to twist the belt unnecessarily or bend in a 90°angle, since it is made with fiberglass; nor should you use tools having sharp edges when installing or removing the belt. Be sure to install the belt with the arrow facing in the same direction it was facing during removal.
  7. After installing the belt, adjust the belt tension by first rotating the crankshaft counterclockwise 1/4 turn. Then, re-tighten the adjusting bolt and finally the tensioner pivot bolt.
  8. Replace the other components removed for belt access.
  9. Start the car, check timing and adjust if necessary WARNING
    Do not remove the adjusting or pivot bolts, only loosen them. When adjusting, do not use any force other than the adjuster spring. If the belt is too tight, it will result in a shortened belt life.

Changing timing belt, car wants to start, but won't stay running


what are you trying to do exactly?
when doing timing belts your not supposed to run the engine to see if anything moves. you rotate the engine over 2 full revolutions and recheck timing marks. depending on the car you have to rotate with tension loose or somewhat tight then loosen and retighted once crankshaft has been rotated 2 full times. remember some engines can be destroyed by a timing belt breaking and installed incorrectly. I have books here so list your car with proper engine. note SOHC,DOHC
