    #4 spark plug blown out

    This is the second time the #4 plug blew out. I had to Loctite it in last time but it blew out anyhow after about 2 months. Is there any hope to fix this without pulling the engine?

    coil over plug question

    Thanks for all the input folks. The bottom line on this is I think the New COP was defective. The plug gap was correct, I did not drop the plug (did that in my early years too). Anyhow, the expy is running better. OBTW it was #6 cylinder- easy to replace. TTL. C YA, till next time
