If you have crank case pressure or overfill the oil pan it's likely that the
plastic oil fill tube is leaking where it slips over the steel tube.
You can remove the plastic extension tube, clean it thoroughly, clean the
steel tube and seal the joint and make a few test runs at 70 mph after the
sealer sets overnight. That should fix it or rule it out.
You can also be leaking through both the front and rear seal and the oil is
blown away before it reaches a measurable point.

Hi,

One question. There is a lot of oily crud next to the fan, where the
oil-filler pipe goes through the rear warm-air plate - I have a theory that
if I am leaking oil out of the oil-filler.pipe.junction, what happens is
that it is sucked into the cooling air, and burned on the cylinders, as well
as blown away as a fine mist - that could explain why I am loosing oil, (one
liter / 350 km) without big clouds of blue smoke, as well as without a BIG
poodle under the engine - that is VERY odd- it doesnt drip, it is oily
underneat the engine - but is does not drip/poodle)

Any input?

Best regards

Jens Jakob
