2000 Dodge/Plymouth/Chrysler Spark Plug Tube Replacement

I have created page to chronicle the repair of a failure point on higher 2.0L Dodge/Plymouth/Chrysler Neons of the plug tube seals. seals nearly always on higher mileage 2.0L causing oil from underneath the cover to pool at the bottom of the plug tubes. Neglect of the Crankcase Ventilation (PCV) can accelerate this failure by pressure to build up in the crankcase, oil past the seals.

Another failure that shows the same symptoms is the separation of the plug tubes themselves their seats in the cylinder

This page is not an official on how to complete the required repair. It is for purposes only. If you choose to the repair using this as a guide you do so at your own risk.

job does not require exceptional or access to special tools a torque wrench and a seal With slow, careful and attention to detail the job is not difficult at

The vehicle shown is a 2000 Neon with a 2.0L cylinder engine and five manual transmission with miles on it. It has not been altered stock form in any meaningful

The spark plug tubes migrate out of the head, resulting in

In order to correct this, the plug tubes must be in the head and ideally the rubber at the tops of the tubes should be also. To access the tubes and seals, the valve cover be removed. Begin by unplugging the plug wires and igntion harness from the ignition

The harness is secured by a plastic that must be disengaged it can be removed. Take notes of of the plug wire order they are removed as well so can be reinstalled in the same order. remove the ignition coil, is by four bolts, one at each Be aware these can sometimes be up, and that they screw metal inserts in a plastic cover, so take care in removal. excessive force may break the bolt, or damage the cover.

Use a good penetrating oil and let it sit for a if it looks like they not come free easily.

the ignition components are removed the two PCV system hoses from the and rear of the valve cover, the valve cover can be removed. It is to the cylinder head by ten bolts, at the front and rear of the cover. For the plastic emblem showing 16 Valve that is present on engines may be removed by gently upward on it to disengage the retainers.

will grant additional room for removing the front bolts. Once all ten bolts are the valve cover should free of the cylinder head. If it not, strike it lightly a rubber mallet to break the between the gasket and the sealing Be gentle, it’s only

If the spark plug tube have migrated especially far out of the head, they may come out of the with the valve cover.

the tube seals will free with the valve

With the valve cover it can be seen how bad the problem is. Often the plugs will be completely in oil, especially if the tube free of the head with the cover.

One or more plugs may be submerged in oil.

The spark tubes are interference-fit, they are pressed into the cylinder and retained by friction. If they are this is obviously a poor so they will be re-seated the cylinder head with the of sleeve-retaining compound: the same used to retain cylinder and other press-fit components you do not want them to vibrate

Unforunately the surfaces of the press fit must be clean and reasonably of oil in order to use such a compound, so the oil be cleaned out of the spark plug seats. This is nearly to do with the rocker arm assembly in the unless you have incredibly hands. If a means is available, or absorb as much of the oil as possible around the spark plugs.

If not, the plug can be removed it to drain into the cylinder, but will cause the vehicle to severely for a while the next it is started as all the oil gets burned Once as much oil has been as possible, remove the spark from the vehicle and store in a clean place if they be reused.

To adequately clean the sealing surfaces the rocker arm must be removed. Before is done, very careful must be taken to ensure they are reinstalled in the exact as when they were Also, piston number one lefthand one if facing the engine the front of the vehicle) must be set to before rocker arm removal.

To this, remove the spark from that cylinder and a probe other clean and tool into the cylinder it makes contact with the Using a wrench, slowly the crankshaft pulley and watch the in the cylinder. Turn engine and for the probe to rise out of the cylinder.

At the where it no longer rises and to sink back into the that cylinder is at top-…-center.

The rocker arm assembly is secured to the head by ten bolts that run the camshaft. Starting at the outermost and working inward, slowly each one by one quater of a turn at a until certain there is no left on the valve springs. If number one is correctly set at TDC, all the should be closed and there be minimal spring pressure.

any pressure is relieved from the loosen, but do not remove the rocker arm bolts. If the bolts are removed all of the rocker arm assembly components can off of their shafts and it is critical they all remain on each in precisely the same order as they came off the vehicle. removed, place each arm shaft assembly in a clean, place.

Keep the rocker arm in a clean, secure place.

the rocker arm assemblies have removed, access to the tube is much easier. Working clean as much of the oil as possible out of the seats, and as much out of the surrounding as well so that it does not or run into the tubes while the is underway. If necessary, use a residue solvent to remove any varnish or on oil that is present on the tubes or in the seats.

Once the tubes and are as clean as possible, apply a bit of sleeve retainer to the bottom of a and place it into the seat. a soft-faced hammer, or a block of drive the tube squarely the cylinder head until it is Repeat this for the other if they are being reseated as

Once the spark plug have been reseated, the seals can be replaced in the valve Working from the underside of the cover, use a seal pick or tool to remove the seals their bores. They can be stuck pretty well, great care to not scratch or damage the bores attempting to pry out.

Take care not to the seal bore when the rubber seals.

Once the old have been removed, the sealing bores as well as and press new rubber seals them. Then, if it is still in its remove the valve cover from the valve cover. the gasket has been removed, clean all dirt and traces of material out of the sealing groove. working from the ends the new gasket into the bore it is uniformly seated and there are no

Do not use RTV silicone in combination with the unless it is recommended by the gasket

After all the new seals and gaskets are in and ready to install, position the arm assembly on the cylinder head. a torque wrench begin the bolts in this sequence:

each fastener to 20 ft/lbs. working carefully to not pinch any of the or seals, reinstall the valve onto the cylinder head. the valve cover bolts in a like the one used to install the arm assembly. Tighten each to 105 inch/lbs (approx 8.75

Then reconnect both PCV hoses to the valve cover, and the ignition coil. There is no spec for the ignition coil but do not overtighten them. Also the spark plugs, tightening to 20 and then reinstall the spark wires in the same order in they were removed. all components are reinstalled, make a check around to make all parts have been installed and all tools are free and of the engine.

Then start the and check for oil leaks. If any oil was allowed to into the engine while the were removed the engine may upon first start up.

All done properly, the spark tubes should be clean and of oil for quite a time to come.
