So I went to do another plug change. Pulled one to see how they looked. Didnt look great and were near .07 on gap so I figured I would change them. But got to love kansas... a storm blew in from no where so I only did one before the rain hit.
My issue is that I have done plugs before but its been a while. It sure didnt seem that the spark plug went in all the way. I mean I know I am not cross threading cuz I start the threads 3 or four turns with a fuel hose. but it just doesnt seem like i am getting near the turns down as i did in the removal.
I drove bout 150mi not long after and it seemed to run fine. Should I be worried or has anyone else had this problem?
I am going to start in on the rest of them in the morning. if it seems they all do this.. then idk. lol

 

How many miles do you have on your truck before you change the plugs?

Thanks,

 

Last changed them about 50k ago. have 187k now

 

I thought the same thing about mine, so I called Ford and they told me that there is a small tapper to the hole, so once you get them finger tight and put a wrench on them they don't run down much more and they are tight, so it seems as tough you are not getting them in all the way compared to most other vehicles.

 

With your technique of the fuel line, you've put plugs in before, what is your gutt telling you? I'd bank on your experience and being concerned or cautious tell me more.

 

after i drove it some last night, im gong to remove that plug again today and see if i can tell if there is a line or any indication in the threads that they were not fully seated.
