4.3, cylinder 1 cracking spark plugs
My 08 Sierra with the 4.3 has 41,000 miles on it. I recently got the the truck 3300 miles ago. I have since replaced the spark plug plug from cylinder one 3 times with a crack in the ceramic. Is this a problem anyone else has had happening to them. I searched the forum for any answers to no avail. A google search I found a discussion from equinox owners have this issue but no talk of which motor they all had in common.I'm assuming the 4.3 possibly.
