Question about Chevrolet Silverado 1500
Enging missing - #6 cylinder is gunked up w/ oil
The engine light is flashing because it is detecting a misfire. Is it a model with individual coil packs, switch the coil with one of the others, see if the fault follows the coil, if it has a distributor and plug leads, do the same with the leads. try to eliminate components. If the fault stays on number 6, then the problem is on the cylinder, need to do a compression test, possible piston rings worn.

If the insulator was cracked the plug would have been misfiring, unless it was broken while trying to remove it. If this oil fouling is an ongoing problem, and you have to keep changing the plug, buy a spark plug that is designed to fire when oil fouling is a problem. You may have to order one from a part catalog, such as JC Whitney. This would keep you going until you can get the problem repaired..

Testimonial: "Thanks, I am hoping I found the problem last night, the intake gaskets on the lower intake were bad around #5 and #8 by the coolant jacket. "
