I got some parts back from the machine shop for a couple of modifications. The pulley is to drive my air conditioning compressor.
I ordered a spin off oil filter adapter made by flexolite, they said, for flaminia and aurelia. It certainly didn't fit my filter housing, being the wrong sized thread, as well not being able to seal with the o ring they provided. It would not have fitted an aurelia either, I felt, as the shoulder on the threaded part would not pass through the body, as intended, because the hole was too small.
Thinking that this was going to be a worthwhile modification, given the frequency of oil changes required (If I am thinking of doing an extended trip this may even be necessary whilst away) I decided to design my own, which you see here. It uses a standard filter seal rather than an O ring and copper compression washers to seal the threaded part.
I finished the parts in satin black so as not to look too out of place under the bonnet.
