I will dismantle and check the Rolt crankcase but suspect that it will be too distorted after the crank breaking.
The original oil pump system with a modified Austin pump was not satisfactory. When I was first racing it was necessary to change the centre main for every meeting, sometimes between practice and race as well.
For the last couple of seasons I ran it with a remote Burton Ford Kent pump supplying oil to the crankshaft at 100 psi. and the Austin pump supplying just the camshaft bearings at normal Austin pressure.
The crankshaft has the rear end modified to take an Austin flywheel and the front extension ( 1 inch dia. ) in place to drive the ancillaries.
