Hi, I've just changed spark plugs, leads, distributor cap, rotor and coil. I now have a loud knocking noise coming from the motor mirroring RPM's

I have a reco 3s-fe motor which has done 40000 and there was no noise before carrying out the work. Car seems to idle alright and there is only one way to install/aline distributor shaft. Not sure if its a timing issue although distributor was reinstall in the same position and don't know why it would make such a loud noise even if timing was out? Any help would be much appreciated

It sounds like when you changed the spark plugs, something may have falling into the cylinder
