Thanks guys,

I'll take care with putting the new fittings on.

Tomguy, I'm not sure of the cam numbers, but I would say only the RHS has had work, as those fittings were black not beer bottle brown. Both the oiler tubes were the same the 10mm round alloy ones and the fiitings only come in 8 and 10mm.

My fittings arn't 2mm loose, they just slide up and down the tubes easly and the end caps can fall off under there own weight. This is where they get the feed from.
The old ones were nice and tight. The fittings seem to expand with heat not contract, unless the oil penatrates into them or something like that.

Guess I'll just have to suck it and see.

Thanks

Damian
