Hi All, Looking for possible solution,
2001 F-150 Smaller V8 "4.8L", "Triton". Driving the vehicle underload "Camper" heard what I though was a loud exhaust leak! Inspection showed that the coil on passenger side/3rd fromt front was dangling on top of the engin block...not a good sign..Turns out that threads are striped and hot gases melted the remaining thread to mount spark plug. I had a local chap come by and re-tap the thread and install a Helix-Coil ?. Have not fired the engine up yet as two things are not certain. 1).Turned engine (without spark) over with new plug in place and a slight leak still present between helix and old thread - not good. 2) how long will this type of patch maintain itself?
I would like to add some type of putty material that could harden would assure a proper seal to this new fix. Can I use a material in conjunction with a spark plug that has a compression washers to further prolong the inevitable...replacement of the head. As this truck has many miles on it ~135k I don't see that value in spending $2000.00 in fixing it. Would like to keep it runnin after a fashion for use on the farm.
Your thoughts.
