New spark plugs without new wireset?

[Stuffy]

Is it no good to just change the spark plugs rather than changing the spark plugs as well as the wireset? One's cheap, one's not. If you don't know already, you can guess which.

Also, has anyone heard of the Technical Service Bulletin for the 93 Rodeo V6 4x2 automatic about oil leaking into the spark plug tubes, and an upgraded wireset being required for some reason? Tell me what you know?

Thanks!

If the wires have over 75k I would change the wires too.

yes. a common problem. isuzu came up with the 'upgraded' wire set as a way to avoid replacing the sparkplug tube seals under warranty which would have required removing both valve covers, an expensive proposition considering all the 3.2 v6 engines. so they came up with these sets which have a larger diameter connector which also has some sealing ridges built in. i suggest you definitely get them. they will keep the oil from reaching your plugs and shorting them out and giving you fits trying to track down the cause of the miss(es). afaik, it's a dealer item, but i've read they may be available other places now.
when you install them, coat the inside with dielectric grease, and put some antiseize on the *outside* so it will be possible to get them off later (this last tip from JLEMOND isuzu xpert.). also make very sure when you install them that they are fully seated onto the plug, it can be difficult to tell sometimes.

good luck

Do you reckon I could talk to JLEMOND about finding out if I already have the upgraded set, and maybe get them from him?

i reckon you could. it's easy enough to tell whether yours is the socalled upgraded set -- remove one and look. if it's like a 'normal' connector that's on many vehicles and has plenty of room to fit in the tube and is easy to remove and doesn't have ridges that just fit into the tube, then you don't have the upgraded set.

Borg Warner also makes the upgraded set. Available from Parts America for less than 40 bones.
