Don't know the official name, but that's the cover for the VANOS. It's not surprising that it gets hot, there's lots of spinning parts and oil under there.

Bingo!!!! That's the valve cover and it runs all the way back as one single piece. The BMW plate on the top just covers the coils.

Why is it surprising that a part of the engine is getting hot?

its very hot , cant even touch it , i think something wrong with it , maybe its not oiled well , some fraction causing heat , im just guessing , am i wrong .
also can you tell me what is the average time to get your coupe 323 warmed up o\in the morning ? mine in 1 min gets warm and ready to move , the temperature meter reach abit after the first blue sign .
maybe im just paranoid from my previous coupe as i had lot of cooling system problems

To use your words....yes, you are being paranoid......so just relax since this is perfectly normal. The valve cover should be hot to the touch and these cars do heat up within a couple of minutes.

Yes, normal......a bunch of lights remain illuminated when the key is in the accessory position and then go off once the engine is running.

You should close the hood and let your mechanic do his job.

That's the VANOS unit which has two pistons in it.

Look at this so you can see what's in there
