The Land Rover has been pushing oil out of the rocker cover breather. I am not sure if it’s coming out around there the breather mounts into the rocker cover. In this joint there is a sealing arrangement which doesn’t not fit snuggly at all, in fact it lose. I’m surprised that the breather has remained on the truck all these years. I used a bit of hose and a breather thingy that I was given by the father-in-law to hopefully prevent oil from bring blown out so much and also made an aluminium insert that means that the whole main breather housing fits very tightly into the rocker cover.
My only concerns about this are that it now means that the engine may not be able to get rid of oil so readily. This oil has been protecting the chassis quite nicely thus far.
