I was actually trying to get the camera to focus on the electrodes, but just didn't work out that way.

I had to look up the procedure for replacing them. That's machine shop duty. Or will replacing the seals take care of this?

I'd say the passenger-side seems to have more fouling/deposits.

Thank you for pointing that one out. Now I have something to compare against in the future.

I want to get an opinion: I am thinking of cleaning these plugs off thoroughly and using them one last time just to see where the oil/deposits end up. Or do they look just too far gone?
