Is anyone still running a Rolt 3 bearing engine in it's original Rolt form?
I was thinking of resurrecting mine but and I can't remember how Stuart arranged the lubrication system.
Mine has been altered over the years (by me).
As supplied by Stuart it had an overbored Austin oil pump and a remote Crosland 493 oil filter.
I'm sure the oil gallery was blanked to give a full flow system?
There is a tapping from the oil gallery to the centre camshaft feed via a waisted block/main bearing stud.
How did the oil get to the centre main bearing? Was it from the modified centre camshaft feed?
