I've got all but one spark plug out of my 5.4. But for some reason I can't get cylinder 8's spark plug out. I have the extractor tool but that is not my problem. Every time I hook up my 9/16 thin wall deep socket (I don't have the special spark plug socket) it feels like it's on it and then as soon as I apply pressure it slips off. It feels as if it is stripped out. I ran a flat head around the plug and blew it out good to see if any thing is lodged in there. I had nothing. Any ideas out there on how to possibly get it out with out running it to a mech?

 

try tapping the socket onto the plug a little, but then you may get the socket stuck in there...the spark plug tool would be great right now...it’s all one piece ...

 

Lol I will give it a go thank you

 

My 4 and 8 did that because water was running down onto the engine from the cowl and it caused the spark plug bases to rust. Had to have a tech back the plugs out with a pick.

 

Its never the no. 1 or 5 is it. Like techrep said but if you tap on it with an extension and it gets stuck you should be able to in theory tap on the extension side to side and get it "unstuck"
