VCU repair

Some time ago I remember reading an article (Australian I think) That told of how to repair a VCU unit it listed oil type and quantities etc. But I cannot find it again. Has any body got a link to the page. I have access to a full engineering workshop so was going to have a go at fixing one.

Was it Ianh1? He hasn't been on in a while so shouldn't be too hard to dig through his posts.

I remember something about the 84% fill volume of the silicone.
