our problem seems to have temporarely went away. we went to the part store and picked up some cheap spark plugs and put those in and the smoking seems to have seized for the moment. i dont see how the spark plugs could have caused the smoking. our leak down test was inconclusive because we could not get any consistent readings. we had one cylinder that was 17 percent and then the next two cylinders left us scratching our heads with a reading of 0 percent. as of now the smoking is not there, we will see if it comes back. thanks for the ideas and help fella's.
