I will send out the breather bottle as this engine was built before we did away with the bottle.
The cooling layout is correct. On the latest sigma engine cars we no longer fit a breather bottle.
I have been looking into the cooling layout to get my head round it before embarking on cutting any pipes. Using a combination of the manual and a few build blogs have come up with the following routing.
Can you check that this is correct?
Also, page 93 mentions two breather pipes that go to a bottle located at the front LH. I can find one pipe (already fitted) and see whether the other one goes (cam cover), but haven’t found a bottle or where it goes.
