Noise, Starter or flyweel Options

[914itis]

I changed my oil today using 20/50 brad penn, and I changed all the gaskets for the exhaust. the exaust sounds beautiful.

My friend was helping me and I decided to take him home. After driving 5 city blocks, I heard a weird noise like the fan is touching something (squeeking). pulled over turned off the car. I try to start the car, the noise is there as the starter is spining.
Pushed the car back home, double check everything, even try to loosen the exhaust, the same thing.

The noise looks like its coming from the starter or flyweel. I removed the coil cable so the car wont start, try to start it and there was no noise. I put the cable back, the car started and the noise dissapeared. but each time i start the car i hear the noise as the starter is spinning, except when the coil is unplug.

during the oil change, I removed the round plate next to the oil plug by accident at the bottom. I put it back the same way.. is my flyweel loose or is it the starter solenoid? why would the solenoid come out as i am driving?

Can this round plate shown in this picture cause my issue. what is the function of this plate and how tight it has to be?

The answer to the first part of the question is maybe (notice maybe, other things need checking first). That nut screws onto a the oil pickup tube and tightens the sump plate up. Unfortunately, VW's design was in my opinion kind of weak since an eye on the top of the oil pick up tube is capture by 8mm case bolt. The problem with tightening it more that the 9.6 ft/lbs of torque is that it can break the boss for that case bolt and that boss is integral with the center camshaft journal. It may be that the cam bore is not true now.

There are probably a bunch of other possible cause to pursue first. I can think of 2 I would start with, checking the area near the fan for something loose, checking the tension on the alternator belt to see if it is slipping.
