General Discussion / 302ci. backfired when starting.

« on: September 14, 2019, 01:25:03 AM »

69 Z-28 302ci. backfired through Carb. and now making metal sounding noise? Pulled covers and push rods, look good. Pulled Distrib. and looks good except for excessive play on shaft, Up and Down, aprox. 1/8 in. play ? ? Pulled Plugs and #1,#3,#2, Carboned & Fouled !!!   #6 Semi Carbonded !! #4,#8,#5,#7, Cylinders real Clean ! Will dump oil tomorrow and check for metal Filings. This is a low mileage original paint,#'s matching  RS Z with only 13,600 miles, and I haven't changed the plugs in Years! But it was running pretty good that day of the Car Show,not missing or anything noticeable.Turned it off when I got home to let it cool down for about 30 min. and when I went to start it up ,it backfired through the Carb. . Shut it down and restarted ,and noticed this Metalic sound ? I kind of wondering , maybe it's the Smog Pump or Diverter Vavle?
