Stuck Spark Plug

[willfxp]

There's a spark plug I can't get off. It's on there TIGHT. The other ones came out fine. I was wondering if I could spray some WD40 down there and see if that'll loosen it up?

Sure wouldn't hurt. What plug is it? On the 5.3L passenger side rear plug is hard to get off due to it's loaction.

Cylinder #1. Nope, WD40 didn't do it. I sprayed a lot in there heh. SEALED. I'm afraid of ripping the top off the spark plug. That would be a bad thing.

I would try some PB Blaster, that stuff is the BEST I've been able to find for losening stuck stuff. I would let it set for awhile then use a breaker bar, making sure the socket is on the plug squarely. Remember, you can always try and tighten it a bit to break it free too.

I second the PB Blaster recommendation! That stuff is just plain awesome.
