From that description I would say unlikely.
Exactly what happened?

well first off its my wifes car not mine ( a VW). And its under a aftermarket warranty. So I cant get my paws on it too much, Well I will be pulling the plug/wires etc. I am getting P0304 so its cylinder 4 misfire. The freeze data shows that at the time of misfire the fuel trim was at -100.4 which is a lot. But I am not getting any fuel system codes at all. So I am leaning towards the plug or wires, hopefully not a gasket. Anyway I havent dealt with many misfires in my time, just never had them. But when the car runs its jerky, which is about right a #4 being out, but there is a distinct tap/click noise which makes me wonder if there is valve or lifter damage.

What kind of car? Don't rule out injectors or even throttle position sensor (losing signal causing a misfire sensation)

po304 i would check the connections to the fuel injector and swap the spark plug,wire and coil with #6 and see what happens,
is this a 6 speed car, i have seen some bent/broken pushrods from overrev, usually mis-shift.
