What have you done today with your Austin Seven

[Alan]

Steve, You don’t need to tap the crankcase. Presumably the stripped thread has left a clearance hole, so what you need to do is remove the camshaft and tap the locating hole in the bronze bearing. Make sure you tap the right hole not the oil feed one. You don’t need a tapped hole in both the crankcase and the bush. You will need to take out the valves and tappet blocks to get the camshaft out but all of that is possible without removing the engine. Good luck.
