Thanks Bill... at the moment I have black fibre washers. I will replace them with copper before resorting to loctite.
This what I use: Dowty washers. I tried fibre, and copper washers neither of which sealed effectively. These sealed well.
where do you get those dowty washers from
Hi K1100, I had the same problem as you after engine rebuild. I eventually put a dab of green thread lock on the bolts. The bolts never loosened and the leaks stopped. I used red fibre washers behind the oil union and flattened the rear face of the union on a surface plate. Cheers Erico
