Some pitting on cam shaft, but no other sign of wear.
The Gauze type oil filter was almost completely blocked..
Replacement filter obtained from Meteor Spares service Ltd.
Re fitted sump, ran engine with flushing oil, then drained and refilled with SAE 30 oil from Witham oil and paint.
Oh nearly forgot, went to Goodwood revival and picked up replacement SU carburettor kit so now the petrol doesn’t overflow from the float chamber.
Engine sounds sweet although there is a bit of smoke from the exhaust. perhaps a top overhaul at some point but that can wait.
Please comments or questions here.
