Have been having fits with one plug on my 92 5.0 L motor. Broke off plug flush with head. Got porcelain and electrode out, been hitting it with Kroil off and on for about 2 weeks, tried a torch to heat head # 5 easy out and the lisle tool. Still no luck. With the lisle tool, is that generally used to pull the portion below the threads for the 5.4 L 3 valve engines ? I believe it is and since I needed the reverse thread, tried to use that on the inside of the plug surface. Well, I managed to simply have it thread all the way into the cylinder I believe, no luck breaking loose from the threads. I no longer see the spark plug tip, so either bent that straight or broke it off in the cylinder ....

How SOL am I now ?? I did read a couple other threads re: using the straight flute but this is the front cylinder and the exhaust manifold is right there on the 4 sided extractor only able to get an adjustable wrench on it, but not square - because of the depth .... Suggestions, short of removing head ??

Thks

 

Ok guys nevermind. Got my answer from a tech at Lisle. Since I could get to the shell of the plug with heat - he recommended go ahead and make it hot. I did and now a happy camper again, now going to replace all 8 plugs with antiseize and no over torque ....

 

Yep, I antisieze any plug I put in. Any new vehicle I work on I always remove them and gob them up. Someone will thank me somewhere down the line.
