Easy No-Sweat Spark Plug Change... Mabye?
If you've run a good brand of gas since day one (Chevron, BP, Shell) then it shouldn't be too bad. A few might be stubborn and make scary noises, but they should ease out. And don't forget the pb blaster.
seafoam them down a few times the week leading up to the plug change & you will cut the amount that break in half. Did mine at 95K miles & only broke 3, another buddy with almost same mileage broke all but 1. ouch
Plug change
Just had mine done at 130,000 kilometers, the was some squeeling on 1and2, the mech. used aero Kroil on the threads and the rest came out, gotta love it when a plan comes together. FS
Turning the engine over may be ok but I wouldn't start my engine on 7 cylinders.The unburned fuel from other cylinder could wash down the cylinders or collect in the catylac converter and ruin the cat.
