Common sources for wet plugs/cops
Common sources for wet plugs/cops
5.4 V8
Bought the truck 2 yrs ago and the COPS were bad after the dealer detailed the engine and got everything wet.
I replaced all plugs and COPS and truck was running great. Lately it's been missing only under load, overdrive, under 1500 RPM. Everywhere else it drives fine. No check engine light.
When I look under the hood the valve cover on the passenger side isn't wet, but it looks clean as if it's getting wet then dries off. I'm assuming I'm getting moisture from somewhere but I can't seem to locate it. AC lines don't seem to drip directly on the valve cover and COPS.
