cleaning crankcase of 4.6
 

Hi guys,
this will be my first post on the forum. here is my question i have a 98 f150 2wd 4.6 the truck began showing signs that it needed a head gasket about 2k miles ago, my coolant reservoir smells like gas and the coolant is a rusty brown color the truck smokes slightly and the oil cap has chocolate moose like substance from the oil mixing with water. I dont care to keep the truck to much longer however i need it to last me to the end of year. I purchased some k-seal and new oil/coolant etc but after thinking about it all of that chocolate moose up in the valve covers will still be in my motor after i perform the oil change and coolant flush. How should i go about attempting to clean the motor out ? seafoam scares me because i do not know if my rings are already damaged from driving while needing the headgasket, Or should i just keep doing oil changes until it looks clean? any help would be much appreciated. :-jammin

Welcome to FTE.

End of the year might be a stretch.

Is it missing or running poorly? Water on a plug?

wasnt missfiring at first, however it just started running alittle rough. was throwin p0302 but i found a loose plug wire and the codes gone. still runs rough tho, i think a plug might be fouled. i dont have the money to fix the motor properly im just trying to get alittle life outa her.

so should i try ATF, diesel fuel or seafoam????
