Thanks, for some good advice

I alrady thought that those chrome timing vovers are crap, but what about those aluminum one's? I just got one cheap from ebay-germany and thought if I just sand it a little and then put the rubber-seal on it with a little sealer to get it not leaking anymore.

Any nummber of that 3-M yellow trim cement so I can get that stuff here in Germany? What kind of RTV is the best since I do not want to change the oilpanseal again!!
