I posted my issue in another department however this seems like a better place to address it (hopefully I don't get in trouble) 89 RS 305, long story short I gained a knocking noise after changing plugs, wires and distributor. I discovered that when disconnecting the EST and timing to 0 there is no knocking and then after plugging EST back in still no knocking. Turn the key to off and then start it up again The knocking comes back. What is happening here??????

 

Check the timing once the ET/BYPASS is plugged back in and the engine restarted. It should move advanced, the timing mark should go toward the passenger side of the car. If it moves toward the drivers side the pickup coil in the distributor is wired backwards.

Also check the firing order of the spark plug wires.

the line does go to the passenger side of the car once I plug the est back in and firing order is all in line. motor man things the main bearing went bad, pulled filter off and oh boy was it full of dirt and there were some metal shaving however I am not so sure it wasn't from cutting the filter open. as I am currently looking for a good used short block I am not going to give up hoping to find some answers
