Wheeping diff plug

Just replaced the washer on the drain plug from a Station Wagon tank.
It was a solid copper washer rather than a composite or folded one. It took a while to get cherry red and still seemed to be fairly hard after quenching, annealed a second time keeping it red for longer.
Fitted and no petrol leaks.

Jeff,

LR1953 hit the nail on the head. Loctite 567 is THE thread sealent for drain, filler and level plugs etc. It also stops them from coming loose, but they are still easily undone with standard tools. The other sealants mentioned also work, but were designed to be used as flange sealants. The leaking brake pipe probably has a damaged flare. I had the same problem myself. New steel Bundy tube with the appropriate double flare should cure the problem, unless the seat in the cylinder is damaged. There are fibre washers on the nipple in the base of the reservoir that can leak also. Good luck!

On my 80" I found cracked seats in the cylinders & one was so bad it had completely come out.
