Hi, folks. While driving my car today all of a sudden it started making a really loud noise. It sounded like a hole in the exhaust pipe, or perhaps like the exhaust had come off the engine altogether. When I got it home and put it up on stands, though, I couldn't see any leak or hole from below. What I could see was a blue flame occaisionally coming from the viscinity of the #3 cylinder, which is definitely where the noise is coming from. But the flame was only visiblle from above, from somewhere under the tin. Because of the tin I could not tell if it was coming from the spark plug hole or not, but it seems to be below that. The blue flame is not visible from below. The spark plug seems to be tight; when I unplug that plug that flame goes away and most of the noise (though of course it runs rough on 3 cylinders).
Anyone want to tell me this is a cheap, easy fix? |
