I noticed a few oil drips on the garage floor but could not decide where it was coming from so tightened the oil hose clips & topped up. A little oil on the outside of the tank but swollen cap gasket seemed no worse. After a 30 mile run to the distillery on returning more oil underneath. Back in the garage oil dripping off the bell housing & lots on the outside of the oil tank. A shred of rubber had come of the cap gasket but was lying on the top of the level indicator in the tank. Matching the shred with the gasket I think I got most of it.

I made another temporary gasket out of two layers of gasket paper.Gasket paper has now gone into my box of essentials to carry in the car. Its easy to make a paper gasket. Lay the paper on the top of the upturned cap & gently tap round the lip with a ball head hammer. This will cut the paper to the correct size to sit in the lip in the cap.
