I had an MG1100 in the mid 60's in Germany. It loved to rev and cruised regularly on the autobahn at an indicated 80-85, but the bearings didn't like it! I had an oil pressure gauge fitted and it got lower and lower until time for my journey back home. Eventually it was reading 5-10 (familiar to a Seven! )but far from the 60 normal. I staggered to Ostend & got it off the ferry. Made it to Canterbury where at a traffic light NOTHING registered! I was opposite Caffyns ...Main BMC Dealers. ...they immediately got at the sump to find that the centre main bearing had disappeared, even the bearing housing was scored and worn! They said the block was scrap and not fit for reconditioning, but as the car was only 14 months old they did wangle an exchange engine...which I had to pay for!
That A type crankshaft must have had a folk memory of a whippy Seven two bearing crankshaft!
I fitted an oil cooler and the engine never dropped below 50 psi in the next two years I had the car.
