ET: Engine (Twin) Anyone know what this is?

[Bill Thomas]

We were told some time ago , Of a chap that had a damaged Oil Filter Chamber ?,
And made up a detached one ?,
Looks like the thread is for the big oil filter cap ?,
I don't use an oil filter , I prefer the oil to flow better , And any heavy rubbish will fall to the bottom ! ?.
Cheers Bill.

Hi again, today I have mounted the ‘unit’ on casing bolts alongside the oil filter. I laid out all the breather pipes ( non crimped ends ) that were in a box. The engine has 3 breather caps on the heads. Without modification or bending, the breather pipes fitted to the ‘unit’ as shown in the photos. There was a breather cap in the box and I have screwed that on with a banjo that had a small length of pipe on it. This pipe sits under the primary casing and looks ready to have an extended pipe pushed on it to breathe behind the rear wheel. Does this look feasible as I have no experience of Vincent engines and may be on the wrong track altogether. Putting this bike together is like doing a jigsaw without the picture on the lid , very interesting though.

Well it sure looks like you have solved the mystery, the only question that remains is, why would anyone go to all this trouble to solve a problem that should not exist.

Peter, couldn’t agree more

I would say " Overkill ", Vincents like to breathe ,
The old Race bikes, Fast Ones , Had a Single big pipe out the Timing case, About 3/4",
So for me yours is Too much, But interesting !.
Cheers Bill.
My Comet is a bit Worn / Loose !, But this pipe out the top into a separator is enough.

I agree with the previous three posters. It is interesting but just should not be necessary. It has several banjo bolts and a breather cap which will come in useful at some stage so my recommendation is to consign it to a box of potentially interesting items to be used as conversation starters and remove much of that extra pipe work. The rest of the bike looks like you are doing a nice job.
