I am new, but I have a few of questions. First, I can not find the oil filter (1985 280 SE). Where is it? This is a Euro model.....

Second, on the oil pressure guage it has a 1 2 and 3. Where should it be reading out at idle and what should it read when driving?

Third, my dip stick o-ring looks warn. Can you get a new one at any parts store?
