[Mini] Oil spitting

[belvenfish at yahoo.co.uk]

Hi Anne,

I don't think you ought to block the crankcase breather, you have
obviously got too much crankcase pressure, so fit a hose into an open tin to
get the fumes out, alternatively into the inlet manifold if you can or
similar. I don't remember what you said about the state of the engine, could
be worn piston rings.

[Mini] Oil spitting
 

After the fuel issues was sorted sorted and the clutch
keeps working fine
with the washer installed, it was time for the Van to think
of another
symptom to come up with.

First it tried to impress me with a
fairly lack of improvement in bhp or
torque (+ 4 and + 10 after fitting the
charger), but as that did not work,
it started to throw out the engine oil.
Although initially not directly a problem, I had a look at where all that
oil
was coming from.
>From the pattern it looked like it was being pushed out of
the dipstick
hole. The stick was not really sticking anymore; just lying in
there.

After I 'solved' this by plugging the dipstick hole, the oil found
other
ways to get out of the block.
Somewhere behind the distributor and also
a bit past the oilfiller cap.
That did become a problem, and not just because
it really DOES need oil,
but also because it was now spitting it over the hot
parts of the engine,
resulting in nasty blue smoke getting into the cabin.

Or
at least I think that is what that smoke was. At least it is very clear
it's
spitting out the oil in places it shoudln't.

Pictures as always can be found
here;

Assuming the remaing crankcase breather (on the
clutch side) was blocked I
took it off the carb nd checked it. Unforunately
(would have been an easy
fix most likely) there is no blockage on either the
engine nor carb side.

Any hints as to what can be done to figure out where
the problem is?

Anne.
