The first thing I thought of doing before a run was give the car a service. Changing the oil It's a little different to what I am used to. There is no external filter, just a mesh in the sump. So sump off. In doing this I found that one of the sump bolts had been sheared previously. Carefully using a left handed drill bit I managed to get this out. Inside the engine looked good - which made me happy. The filter was OK, but worth changing. Here is the filter before and after: Unlike a more modern ('50s onwards) where you would just put on a new filter I had to made one up. There was a little sludge in the bottom of the sump, but it cleaned up nicely. I also fitted a new sump plug. In the end it got all new gaskets, new sump plug, new sump bolts, new gauze filter. I topped up with Millers Oil Vintage 30. I've used Millers a lot and, after research, saw that this was the best grade for a Seven. Unfortunately I put slightly too much in, so had to drain off a small amount through the plug.
