- Mark the distributor cap and the distributor
body to make alignment easier when re-installing. Take the distributor cap off of the distributor. This is an excellent time
to inspect the distributor cap and rotor button. If they need replacing, do so at this time. I recommend to leave the spark
plug wires connected if at all possible. If you do have to take the wires off to perform the following steps or if replacing
the cap, mark the wires and the corresponding receptacle that they plug into so as to limit confusion when re-installing.
- Clean the edges of the distributor and the cap
with a spray cleaner such as brake cleaner, carb cleaner or a comparable cleaner that will evaporate quickly and not leave
an oily residue.
- Most distributors have a rubber plug that the
wires pass through on the side of the body. You should be able to, using caution to not nick or scar the wires,pull this plug
up and out of it's seat. Clean this plug and it's seat with the same spray cleaner used in step #2.
- If your distributor cap has a vent cap on
the top, you will need to either push this cap out from the bottom or pry it off from the top. Be careful to not break the
vent cap body on the distributor cap itself. If your cap doesn't have this vent cap, there are 2 opinions concerning this
next step. The first opinion is that you need to drill a hole in the cap in a location to not interfere with the inner workings
of the rotor button. The hole should be big enough to slip a piece of rubber hose tightly through just far enough to apply
ATV Silicone(resist oils) to the top and the bottom of the cap around the hose to seal it off. This will allow any moisture
that may enter the cap to evaporate as well as prevent pressure build up. The hose should be big enough to fit the line fitting
on the breather we will discuss later. The second opinion is that you don't need this vent. My opinion is that if you didn't
need them then why did they start putting them on newer caps. If you are replacing your cap, chances are that it will have
a vent already on it, so it might be worth it to just replace the cap. They are cheap and it will prevent you from having
to do this again anytime soon. Always replace the rotor button when replacing the cap, they are cheap also.
- Apply a liberal amount of ATV Silicone(resistant
to oils) to the seat for the rubber plug removed in step #3 and re-install the plug into it's original seat. Then apply the ATV
Silicone to either the seat just inside the edge of the distributor body or the seat located just inside the edge on
the cap. You want to apply enough to seal it but not an excessive amount.
- Let the ATV Silicone skin over as per the instructions
on the tube and re-install the distributor cap. Line up the marks you made in step #1 on the cap and distributor and re-install
the cap. Tighten down the fasteners for the cap. Re-install the spark plug wires if they were removed.
- Next acquire vent filter P/N 4612901 from your local
Dodge dealer. This is a great vent filter that has a large line fitting, built-in mounting bracket and a good paper filter
inside. I think it is for a Plymouth Breeze. Find a location as high as you can above the distributor and relatively close
on the fire wall to mount the vent filter. Run a hose that will fit tightly over both the line fitting on the filter and the
line fitting on the distributor cap. Attach the hose to the distributor cap line fitting and secure with a hose clamp. Now
run the hose to the vent filter you mounted on the fire wall being careful to leave enough slack so it can move with the engine
but will not kink, get hung up on anything or get into any rotating components. Slide a hose clamp over the hose and slip
the hose onto the vent filter line fitting and secure with the hose clamp.
- Apply die-electric grease to the insides of all spark plug wires at both ends
and the coil wire at both ends. Any auto parts store should have this grease. It will keep out the water while not conducting
