Two outings this year, both under 15 miles, two soft plugs blown out of the "F". Now I am afraid to drive it anywhere other than around town. After 31 years of total reliability, it has now become totally unreliable. Maybe coincidental? But I'm not willing to gamble on it. This fall I will be (hopefully) be able to replace the remaining 8 plugs -- that seems to be the only remedy that is practical now. In the meantime, the (heresy, I know) Chevelle will do car events.

They fit in a champfer and bottom out with the curve facing up. Then they are hit down flat which expands them. There is a tool for this so they don't get pushed too far and loosened again. Same thing happened to me. The shop that did the heads just used a ball peen hammer. ----- Original Message ----- From: Michael Reed Date: Sunday, May 23, 2010 5:55 am Subject: [Chrysler300] Soft Plugs Revisited -- Two Losses To: "Chrysler 300 Club Intl." > On its first drive this year, the "F" popped a soft plug (left > head, front) about 12 miles from town.
