1984 330D New Monarks

Hi all at Mercedessource and forum. I put the Monark injectors in "Old Yella today. The instructions were great as usual and every thing went smooth. I had one minor disappointment and one question and would like a little advice on both. First the disappointment: You know how you get a little diesel fuel around the pre-chamber and the wells that the injectors sit in as you expell the air from the hard lines with the nuts cracked a 1/4 to a 1/2 turn? Okay, well I did everything to a tee. I torqued all the injectors at 59 ft/lbs.

1980 240d alternator troubleshoot

car wouldn't start, pulled voltage regulator, inner brush was worn out, while outer was over 1/4 inch. both were worn with same concave profile. does this spell alternator trouble?
i installed a borrowed voltage regulator, and all seemed ok first day. now, at idle, if i turn the lights on, it changes pitch of the engine. the engine bay is clean, and alternator looks newer even though the car has way over 300k.

1984 300D intermittent erratic temp. guage

Anyone ever experience this: "Old Yella" runs great as I have been retired a little over 2 years now and the car has become a hobby to me as well as my daily driver. With the help of this site I have got the vehicle pretty much re-born. There is one thing that I haven't been able to remedy. The car's water temp guage reads right where Mercedessource states it should 99% of the time,(a picture of the guage reading is on this site or in one of the manuals) just around the 80 degree celsius mark.
