I found a piece of automotive plastic on the roadside, it was the right shape. Took it home cut it to length, fitted the spine of a (4) lever arch file, trimmed the arms and covered them with small diameter fuel hose.
The arms needed a spacer to keep the pressure on and make a snug fit. I also fitted a length of 5m bolt into a casting sleeve on the cam cover and fixed it with a butterfly nut.
Low cost solution and no water ingress!
All the best
Tony
