The following pictures are of a very fine 1955, 100 + mph, Alvis "Grey Lady".
Sadly this much enjoyed car arrived with a little tell tale "knock" on occasional start up and running, despite a healthy oil pressure. The owner, very wisely, felt it should be investigated a little more. Unfortunately the bearing shells are quite worn and several journals too. The oil pump will require an overhaul as well as a few small details to attend to within the engine. The cylinder head is in very good condition after a lot of hard work by the owner of this lovely car.
Initial investigation with a bore scope and an externally pressurised gallery to show any abnormal clearances highlighted by copious oil flow from the offending areas.
