Question about wires and cop boots
I pulled the plugs in cylinder 1 to have a look and noticed when I took the coil off that there wasn't a distinct feel that the connection inside the boot was very good. Also the ceramic outside the cylinder has a brown ring right at the metal. The coil just lifted off with no resistance to indicate the plug and boot are making a good connection. Should I feel a click when pushing the coil back on like I do with the regular boots on the wires? It is an 05 GC 5.7L. All plugs were recently replaced before I bought it.

Re: Question about wires and cop boots
i thought the same when i got mine, however its normal. the coil only has a spring that keep pressure on the plug , no "snapping". the brown that you're mentioning, is it dirty(normal) or wet oil? the valve covers have "o" rings that seal the plug area, sometimes they seep.

It's not oil or dirt, almost like a burn ring
