My 1955 B31 is remarkably free from oil leaks, but I have noticed a small leak from one of the screws fixing what I now know is called the "valve rocker inspection" (little plate at the top of the pushrod tube).
All 4 screws are done up tight.
Any suggestions on best way to eliminate this leak?
Ideally a very thin aluminium washer - if you could turn one up, under the head would do it or a small thin O ring.
Another method would be some PTFE tape on the last few theads nearest the head of the bolt so the oil couldn't track up the thread.

I hadn't realised that oil was coming up the screw thread, but it's obvious now you've said it.
