jimmy_neutron Posted February 12, 2008 Share Posted February 12, 2008 Whilst doing a bit of engine work recently, i noticed a little bit of oil in my air filter. I just wiped it out like normal as it was only a little bit and hadn't contaminated the air filter. Cos the sun was shining i thought i would replace the o-ring on the oil/air seperator fitted on the rocker. Whilst there i thought i would clean the gauze filter. There is no gauze. So, no wonder i'm getting oil in the air filter. I went to see someone i know to examine their's. No gauze either. Surely this makes the black thing on the side of the rocker a totally useless item ??? Is this why we all suffer from engine oil in the air filter ??

Lars L Posted February 12, 2008 Share Posted February 12, 2008 I think the idea is that it should trap liquid to get that to the sump and let the fumes pass. Maybe not the most effective design... Quote Link to comment Share on other sites More sharing options...
jimmy_neutron Posted February 12, 2008 Author Share Posted February 12, 2008 Every other car that i've worked on has had the same item, but stuffed full of wire wool kind of stuff to collect the oil from the vapour. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted February 12, 2008 Share Posted February 12, 2008 I think land Rover call it a separator - fumes go back into the inlet hose and the oil is SUPPOSED to drain out of the bottom and back to the sump but as you know it doesn't all go back. I've noticed on the 300s that the breather fume pipe join the inlet hole further down the line probably so as to cure the filter contamination problem.

Is this why we all suffer from engine oil in the air filter ?? the breather is a Cyclonic type so it causes the vapours to spin & drop the majority of oil back into the sump via the drain tube, you'll always gte some oil in the filter, it's virtually unaviodable & doesn't cause any long lasting harm.
