Cossie-Iain: Yes got the radiator cap from Graham Goode, but Demon Tweeks also sell the same cap. It’s a Stant Racing Radiator Cap with lever release. £18.32 plus vat from Demon Tweeks.

Azrael: The only problem in putting a swirl pot on, is that you need an out let for the air release. Therefore need a fitting into the header tank. The oil is separated in the three port separator, and then the oil is fed back into the sump via the standard oil return feed from the standard oil separator. Look under the inlet manifold towards the back of the engine where the block joins the sump.
