tune up for MH

[jagcb750]

I am getting ready to do a tune up on Nancy I was going to change out the:

1 oil and oil filter
2 spark plug and plug wires
3 air filter
4 distributor cap and rotary button
5 coils (this thing does have coils on it doesn't it? 454 gas engine)
6 transmission filter and gasket (pan is leaking a little)

What else should I look into? I am going to look around for a maintenance schedule pamphlet. Seems like I saw one with my paperwork. I read on a post in this forum somewhere about fuel filters, so I am going to try to read up on this to see how many and where they are. Are there any smog control type filters or egr valves or anything? Anyways any advice on this would be appreciated as always. Thanks

Reference item 5, your motor does have a coil, and it is probably mounted on top of the distributor cap. Coils are not usually considered maintenance items though.

Item 6 - A new filter won't hurt anything, but you may want to let a reputable transmission shop replace it. A skilled technician can tell you a lot about the transmission simply by looking at what has settled in the pan.

Are there any smog control type filters or egr valves or anything?

Inside the carb air filter housing, on the left-hand side, is a small, sponge-type filter. In a new engine, air is drawn through this filter into the passenger-side rocker arm cover. In an old or ailing engine, engine fumes & oil are blown into the filter (not good). Clean the filter and make note of which category your motor falls in.

The PCV valve is mounted on the driver-side valve cover. Remove & clean it with carb spray, or replace it.

What shape are the belts & hoses in?

If it has been more than two years since it was done, deain and refill the coolant. It will eventually turn acidic, and cause things to go bad on you. A couple of gallons or so of coolant is cheap insurance.
While you are doing this, if you already haven't, it woulod be a good idea to \change the thermostat and gasket. Check the end of the fan clutch to make sure it doesn't have oil oozing from the center, and replace both fuel filters if you haven't gone it recently. Also, check the level of gear lube in the differential, and make sure you grease everything with a grease fitting. Some fittings are in places you wouldn't think to look.

Electronic ignition does not have breaker points.

thanks to all that replied. I plan on getting at least some of the items done this weekend.

I changed the rotor, ignition module, condensor, and distributor cap and coils today before I went into work today. I read the sticky in this forum and got the ignition module and condensor the other day. Now I need to change the plug wires still and do the other basic type tune up items. I noticed that the wires I got which are not factory do not connect to the plastic ring-thing that sits on top of the distributor cap. I guess they should work o.k. other than that. They are, I believe, AC Delco. Anyway, awesome sticky, Thanks for the great pics.

[jagcb750]

Anybody know the part number for the original spark plug wires that snap into the retainer ring that sits on top of the distributor cap is?

Here is a picture from the web of the ring.

[richinny]

i would think that any delco set would work?

[jagcb750]

I tried two different ac / delco sets and neither snaps onto this ring. I kinda like the idea of being able to lift the ring off and take the distributor cap off without having to mark my plug wires to work on changing a rotor or ignition module or capacitor.

[richinny]

maybe you could try bringing the ring to the place where you bought them and see what they say? my experience might be getting dated :-(

possibly a new ring might fit the new wire and the old distributor.

Have I gloated lately about not having to worry about tune-ups ?

Tell me Gracie: Why do you not have to worry about tune-ups?

Chaplain, you crack me up!! Ha Ha!

Here is an update: After I installed new spark plugs which were ac delco 10's which are a rapid fire plug, I went to start her up. Ran like the choke was stuck and could hear a weird clicking noise in the distributor. Then it backfired really loud and stalled itself. I took off the new components that I had on it (distributor cap, ignition module, capacitor and rotor button) and put the old stuff back on it and runs fine. I do believe my choke is sticking a little. I am going to replace one component at a time to figure out which is faulty. I suspect it may be the new ignition module.
