Spark Plugs
« on: February 13, 2019, 05:05:50 pm »
Rainy day in San Diego... so I have changed the plugs in my 69 more than a few times.  The first time it was a bee-itch.  Asking questions and reading what some of you guys were doing it got progressively less of a bee-itch.  Extensions, swivel sockets, with or with-out valve covers still gotta be the hardest car I have ever changed plugs on.  All the while trying out what ever tool was handy to speed up the process.  Biggest problem plugs, for me, are 7 and 8.  Now I have a sure-fire method for getting a socket and ratchet on those guys and thought I'd share.  Using a shorty 3/8's swivel head, a plug socket and a socket it is actually possible to get my hands and tools in there to do the job.  There is no need to remove the valve covers.  So now I have a satisfactory method for the plug removal and install.  Next hurdle is the wires and boots.  Getting the wires and boots off and on is another bee-itch operation.  Currently using a pair of long handle pliers is the best I can manage.  Once off and prior to re-installing I squirt the boot and wire with Boeshield T-9 so I can get the boot to slide back down over the plug end.  Of course this requires a combination of hands, fingers, pliers and some liberal verbal coaxing.  I don't have any smog stuff on my car and that makes a plug change a bit easier ?  Some of you guys do this with smog in place and don't seem to think it's a big deal.   Still takes me an hour maybe even two ?  Anyone have a better method for dealing with the wires and boots.  Thanks, Brian

The chrome covers on my 68 make it easier than the aluminum covers on my 69 and the no brake booster really helps . I hate changing plugs on the 69 .
had many 428 CJ and SCJ cars over the last 30 years.I currently own a 68 1/2 coupe and a 69 R code SCJ Coupe and a 70 R code SCJ Cougar Eliminator .I am looking for a 70 428 coupe if anybody knows of one for sale.

I picked up an impact swivel socket. Some say that makes it much easier but I have yet to try it.

If you have smog it is way easier with the tubes removed as well as the valve covers.
They can be a big pita other wise.

In the mid 70s we were drag racing a 67 fastback with a FE in it. #8 cylinder was giving me trouble, could change it between elimation rounds. Using a swivel and a long extension that would clear the brake booster, to remove the plug. Then slip a rubber hose over the new plug to start the plug in the head without cross threading it, and then use the same tools with the long extension to tighten.

I can change an entire set in about 15 minutes. Now this is with pent roof aluminum Le Mans covers on my Shelby. I use no short rachets. I don't have smog.  Does your vehicle have smog?

Thanks for the input.  Yes the long extension is a favorite with some of the guys and I have used mine before.  I don't think I would use an impact anything anywhere near my heads ?  I like the looks of that S&K 3870 rachet and will see If I can scare one up somewhere.  Although I suspect the handle length may be a problem ?  The wires and boots are a ' just do the best you can ' ?  Brian

FYI. Harbor Freight sells a clone for 20 bucks.

They do? Which one? This is the closest I was able to find, and it doesn't pivot around the ratchet head like the S-K wrench does.

+2 - on using vacuum hose to turn the plug. There is new thinking on using anti seize on the threads (especially on aluminum heads) as the reduction in friction can over torque the plug and damage the threads.
