How often do you replace your msd cap/rotor, coil and wires?

I'm just wondering how long we can expect our sixlitre tune ups to last.

How many miles/ years would you do another tune up?

There really isnt a solid answer to that question given variables like:
Mileage driven
Driving conditions
Vehicle type
Life of individual parts, quality of parts etc..

I inspect the spark plugs, cap, & rotor about every 15,000 or so (two oil changes for me), and replace as necessary.

im with sig but i check my stuff every oil change then replace when needed

I know to replace the caps when there is no contacts left and the rotor looks worn. any cracks, you should also replace.

what about wires? how do you check them?\

What about coils?

you can all ways ohm your wires

and the coil has has a bar code scanner that needs to be scanned and it will tell you the expiration date

It used to be a tune-up every 30,000 miles. With copper plugs, I would say they would be done by then, but as far as the cap and rotor and wires, I would just visually look them over.

When it quits running good :toothless :goodfinge

I'd say check everything over every 10k miles or so. Change stuff out when needed. :shrug

It also depends on the quality of the parts you install. I dont trust any part enough to just let it go for say 50k miles. I check that stuff about every third oil change. I thought you would know this chit Need4racin...

maybe on the latter part, never heard that. But checking resistance in your wires (ohms) is easy if you have a gauge. You can then compare to what should be decent for your length of wires.

Other than wires, I'm roughly with Sigepblue on cap/rotor/plugs on miles. My Jacobs wires have been in since 55k or about 10yrs so I can tell you they are good wires, and I should check them, but the've been perfect, and the truck is idling smooth, so I hate pulling on them when I don't believe anything is wrong with them. what a quality product they were.


so I hate pulling on them when I don't believe anything is wrong with them.......

And Steve83, don't go misquoting me on this, I know it's election time, but this would be taken out of context.:goodfinge:toothless

I know i haven't met my quota on stupid threads.

 

[95thebroncoman351]

there is a certain amount of resistance allowed for the length of the actual plug wire,

bar code :histerica

and the coil should show 12 volts.

I must of been bored when I started this thread.

I'm going to put this thread in honor of Rednek.
