I had drained the oil a few weeks ago so I thought there would be nothing in the sump, I've rebuilt quite a few engines in the past but I didn't expect to see sludge an inch deep filling the entire sump bottom! This engine ran perfectly when it was in the car, great oil pressure and no unusual noises at all-I don't think the sludge appeared overnite, and engines that have been left for years don't go like this. When I drained the oil and removed the filter&housing, the oil was cleanish with only a few particles in it,it says a lot for the resilience of Morris engines if it could work through that crap with the mesh oil pickup strainer buried in it.
10 minutes with some rags and parraffin got the sump back to its original condition, can't wait to take the cylinder head off.....
