I know what ya mean there BlueOvalFitter there are techs that look the other way but they just dont know no better. LOL
The gasket problem was with the head gasket material and design. The cast iron block and aluminum cylinder heads expand at different rates as the engine heats and cools causing the gasket to move or slip between them losing contact with the head or block eventually causing failure. This happens on almost all aluminum head cast iron block designs eventually. Some like the 4.2 more rapidly than others. They have revised the gaskets but I think the engine design has a lot to do with it.

COP's May be fixed this time???
I may have discovered the fix for so many COPs going bad. It seems to be in the 2 small control wires that plug into them. This is especially true for #4. The heater hoses lay right on top of these small wires thereby heating them to the point that the voltage is dropping below what is required to fire th COPs.
I have loosely tiewrapped the heater hoses back and not had the #4 problem return for 9 months.
However I have had several #5 COP's fail on other (neighbors) Tritons and have yet to find the cause. On occation I have simply removed and pulled (lenghtened) on the spring inside the Cop's...... reinstalled with no misfire. This was a suggestion for a Ford tech.
Hope this helps,

Update: The #4 coil fix is still holding. I haven't had it come back to date, so this looks like the fix at least for #4 coil anyway. It seems the COP failure has died down, I only get 2-3 a year now, in various cylinders. Cleaning the connection at the spark plug has solved most of them. Stretch the spring and use dielectric grease.
