1931 RN saloon 2 bearing crank.
From running perfectly fir the last two years, last week developed a buzzing noise from the front of the engine that migrated into a knock during the day.
Looked into the sump. No signs of any damage. Front crank bearing has been upgraded with bolt on lip.
Dynamo bearings were both a bit loose, replaced them.
Put it back together and now there is a knock only at tickover coming from the area of the front camshaft pulley.
Engine runs well otherwise.
Would I be right in suspecting play in the front camshaft bearing leading to interference with the dynamo drive gear?
