oil in the air filter!

[hermeneuti]

I have a Micra 1 litre 2001 motor. It has a lpg conversion. I continue to get oil in the air filter. I have had a new air flow sensor fitted but this doesnt seem to have cured it. For me the only source for the oil is the hose coming from the rocker box cover and into the air filter.....but i am open to any advice and suggestions....


thank you for your time

Michael

i,ve had no problems like that with my many years of running on lpg michael, maybe you have too much crankcase pressure ? (you could try removing the intake pipe and fitting it to a catchtank maybe)
