5.4L problems

[sxyxc]

okay this isn't on a mustang but its still a modular motor.
i have a5.4l Triton in my 01 f-150 (miss my mustang)
well i dropped a COP, drove on it back from school and got a used on put on for free, so cool. well about a week later the same symptoms showed up so i believe i lost another one. but this time i actually was stupid, don't have much money, and i have to drive to school and back. well i have have driven roughly 400 miles with a cop out (i know stupid)

i was wondering about the chances of fuel blow bye and if i may have caused damage to my truck. i know there is fuel in the oil, i can smell it on the dip stick so i need to change that out when i get new COPs..

also i was wondering, with just stock right now (tow alot) if getting some aftermarket COPs will help anything, nothing too expensive (Christmas gift) but something like an Accel if i would notice any better performance for towing over replacing with stock COPs (they are around the same price if i buy the COPs from the dealer)

well by the sounds of it you may have "washed" a cylinder. thats not a good thing. getting a set of aftermarkets COP's may help a little but not much over stock on stock HP.

you are going to have to pull all the plugs and let it sit like that to dry out the cylinders. reinstall new plugs and new cops and see what happens.

You have also been dumping raw fuel down the exhaust. you are ruining your catalytic converters and your 02 sensors. those are expensive.

You may see some improvement from aftermarket coils, but probably not enough to justify the cost. Get a set from a junkyard and keep them around for cases just like yours when one fails you have another handy. You would probably see a better improvement in HP from a quality catback exhaust than fancy COPS.

the truck is currently bone stock with 120,200 miles,
this all happening really makes me mad because i put some new plugs in it not too long ago, about a month, then everything started to go to crap with the cops, i am thinking that the ones that went out where probably the ones that were supersoked in coolant when my heater core went out and i had to cut the heater core lines, coolant got everywhere.

and the Aftermarket coils are only like $180 for a full set.. so i don't think thats too bad..

as for the possibility of ruining my cats and o2 sensors what can i do about that??
