I am attempting to do a spark plug change on a new to me 2003 Tundra with the 4.7l V8. I was told it has the original copper plugs in it and it now has a little over 100k miles on it. It still runs well but I would like to change the plugs as preventative maintenance.
Upon attempting to remove a couple of the plugs, I am able to break the free, but I can hardly turn them before they start to bind in the threads. I have never had a spark plug not just spin out relatively easily once being broken free, so I just torqued them back into place for now.
Any ideas on how to get these plugs out without breaking them or stripping out the threads? Considered some PB blaster, but thought I would check here for any ideas first. The plug holes are about 6" deep, so difficult to really see the plug at the bottom of the hole.
Thanks
