removing spark plugs.

Post by wschneid »

I have an 86 32' FB sedan with the twin Chrysler 318's as usual. I recently got the boat and want to check the spark plugs. I am having a lot of trouble with removing the spark plug wires from the spark plugs. I'm afaid of breaking somethings. Is there any secret to getting these wires off? I have removed spark plugs off of many auto engines and never had this much resistance.

Try giving the plug wires a twist at the plug boot to break the seal. When reinstalling use some dielectric grease on the plugs to make it easier to remove in the future.

They make a spark plug wire puller "cheap" . Try that.

If you had that much trouble, I'd suggest replacing the wires as well. They might be damaged.

Jeff,

Back on the old site you talked about replacing wires with a GM set (extra long?)so that routing wasn't a major issue (routing - I'm not sure...). Could you detail that again. I'm sure others would benefit from any and all info you could provide.

Thx,
Bill

I used wires for a big block Chevy. You need to take an existing wire with you to your parts store to be sure you get the same type connectors on each end.

Routing them around (instead of through) those super close manifolds reduces errors and misfiring.

Good luck!

Okay, I bought a spark plug wire puller and it worked fine. Now the two sockets I have used on automobiles won't fit. I have the std. Chrysler 318, 240 HP engines. What type of spark plug socket have you guys used to remove the plugs?

Up until the time that Ford introduced the 4.6 L in the Crown Vic, all domestic spark plugs used a 5/8" socket or 13/16". Small two cycle engines may have used odd-ball sizes, but all domestic big engines used these sizes. If you go buy a set, make sure they are for spark plugs, as a good set will have a foam rubber insert, to protect the porcelain part from being cracked, while tightening the plug. Note of caution: the 5/8 plugs seal by the machined bevel at the seat of the threads, where-as the 13/16 ones have a little stainless steel gasket/washer for the threads. Washer HAS to be installed or the plug won't stay tight and possibly blow out the head. Mike sure not to drop the little washer in the bilge too, or it may get sucked into your bilge pump !

One more thing. What spark plug do you guys use on the Chrysler 318 engine?
