front plug is starting to leak. Question is how do you remove it,and how do you install a new one? Haven't scraped off the paint yet to see if it's brass or steel. Which is the better type to install?
Drive a flat tip screw driver in the center of the old plug and pry it out. Be sure and clean the ridge in the hole down to bright metal with a knife and use the sealer of your choice on the new plug. Use the back end if a punch to set the new plug.
Both brass and steel will work, even a nickel cupped in a socket will work, but a steel plug may rust out again just like your old one.
I always use a nickel. After all, that is where the statement "It isn't worth a plug nickel" came from.
Now that I LOOKED AT ALL OF THEM, THEY ALL HAVE RUST AROUND THEM WITH THE FRONT ONE LEAKING MIGHT AS WELL REPLACE ALL OF THEM ! ARE YOU REFERRING TO GASKET SEALER?
I have used red hi temp RTV on brass plugs in the past with good results. One downside I have found with brass plugs is that although they don't corrode, engine paint doesn't seem to stick to them very well over the long term.
Thanks Mark and rest of you that took time to reply. I'm going to go with the brass.
The Dauntless Geezer has my favorite plugs. (The local bank saved me a few [for only 5 cents each] ) so I am ready when the time comes.
Look at the pictures here for ideas....
