Is your engine wet or dry sump? If dry sump than there should be a breather on the separate oil tank. As far as I know, that's the only one. I'm impressed that the cover over the fuel pumps seals well enough to push the mist out of the breather hole: on my engine the gaps around the cover must be an order of magnitude greater area than the breather. It's probably worth removing the cover over the fuel pumps and checking the two little wells at either end. They catch any diesel leaked from the pumps and emptying them is a service item. If they are full that might be the source of oil mist. Obligatory plug again: try asking on the Lister FR mailing list: we're not numerous and it's not high volume, but the more FR owners on there, the more useful it will be: <http://lists.thekelleys.org.uk/cgi-bin/mailman/listinfo/lister-fr> Cheers, Simon.
