just finished installing my rebuilt motor and upon starting i have a knock. the motor was test run by the rebuilder and he said it was fine with no noise. i had to remove the distributor in order to install the ignition lock cable and when i went to take the distributor out it like "sprang" back into the block. i rotated the motor slightly with the crank and it came out.. i put the cable in and reinstalled it with the rotor facing the same place as when i removed it. i started the motor and i have a knock. the rebuilder says it was fine when it left his place and i must of done something like maybe the timing was off. i am confused because if i took the distributor out with the rotor facing a certain direction and reinstalled it in the same place how would the timing have changed. any suggestions i am super stressed and dont know what to do.
 
also i had to push down on the distributor shaft in order to get the distributor to go all the way down into the head
 
Bingo
Should not have to push down on the distributor to get it in better be checking what you have going on down in that little hole

I had a problem with a new repo front crank pulley hitting the front engine mounting yoke. Sounded real bad The yoke left marks on the spokes of the pulley.
 
not familiar with that part i think there is a spring that the oil pump floats on and the rebuilder says that the distributor was pulled down by that spring

No magic wand here. You need to get the engine back to the rebuilder so he can hear it. Just load the car on a trailer and zip on over to the rebuilder's shop. So what if you're out some time and money! That goes along with this hobby and is to be expected from time to time.
And remember, you catch more flies with honey than vinegar!
 
i remember back about 50 years, when i said to my dad, i should have a mechanic work on this for me, my dad said to me, "you may as well fix it yourself because you will likely have to redo the work anyway.

i hate when someone gets told "it was fine when it left here" the answer should be "ill have a look at it for you". it would make me want to deliver it back through their front window.
sorry for the rant.

knocks are horrible things to diagnose.

stethoscope or a pc of hardwood to your ear to try to narrow down the area it is in.

sorry i cant help more.
