I removed my recently refurbed dizzy to find 2 small screws have come a drift in the actuall distributor body,Now there is a metal disc in the internal of the dizzy with 4 pegs that stick out/down and the screws have got caught in here and the pegs !!

I stuck on a new dizzy yesterday,Car fired no problem but has a really promenent ticking/knocking noise !!!

I'm just after opinion on this ?

What else should I be looking at to see where the noise is coming from ?

Could the force of the engine turning(car cutout at about 50mph) and the screw jamming the dizzy have caused the timing to jump ??

My first reaction was bent valves ?

If it were the valves,What other symptoms would be showing ?

I'm going to go out and do another compression test today,I did check yesterday but my head was in it !!

where is the noise coming from? is it the dizzy or the engine? top end? bottom end?

Sounds like topend and coming from the head area

Did you remember and give the replacement distributor a tiny spot (n.b. tiny ) of oil before you fitted it --- if a distributor is dry of lubricant it will tick..

Normally way to this put a single drip of engine oil on screw revealed when the rotor arm is removed also two drips of oil below the base plate. best to allow a few minutes for excess oil to drain down before starting the engine.

I never oiled the distributor at all !!

I've just done a compression test and the compression is down on what it was.

Before I had 185psi across the 4 cylinders now I have 185/170/170/150.

I have also just timed it back up and the timing seems to be in the original position !!
