Have you checked the cooling system fan
I had a similar problem once with a friends 1600 beetle. Turned out that the
fan had unscrewed itself
Different engine I realise but maybe the same problem.

Subject: An Introduction and noise question

Almost immediately I noticed a grinding type of noise once it warmed up. To
me it
sounded like the flywheel rubbing. I do have a cylinder running at 65 psi,
all others are about 90 to 110 which is actually another question but I
don't think it is
related to the noise. I've got a tempature gauge and at first startup the
engine runs beautifully
at about 210. After about 20 minutes the noise starts and the temp slowly
rises to a n overheat. The noise seems to only appear at idle or very low
engine loads.
