Crossflows are notorious for leaking oil, which might have been acceptable in th 1960s but is now a bit embarrassing. I decided to try and do better, and a close look at the sump flange showed that at least a third of the holes were pulled proud of the mating surface. Some attention with a hammer brought them down slightly below flush, which means the bolts should now pull the flange down on the gasket.

With the engine inverted on an engine stand, it's also really easy to see what you are doing. I decided to do the bolts up by feel rather than using a torque wrench. I took this really slowly, going round the bolts at least 10 times. It brings home the fact that it's very easy to get the sump on slightly skewed or wedged, which must become more likely if you are lying on the ground under your car.

Time will tell how well I did.
