C180 Breather problem?

[cuparboy]

Hi.
I have just acquired a 1995 C180 automatic; 92,000 miles and generally very good condition.

The other day I was on the motorway doing about 85 -90 and there was suddenly a large cloud of blue smoke behind the driver's side of the rear of the car. (it's a UK right hand drive with the exhaust on the passenger or left hand side. I'm assuming that the airflow turbulence at the rear of the car caused the smoke to appear to be issuing from the opposite side to the exhaust.)

This continued for what seemed ages but was likely just a minute or so and then just stopped.

My thoughts are that there might be a blockage in the crankcase breather filter, causing some oil to force its way past the piston rings - this phenomenon ceasing when the blow off relieved the pressure in the crankcase.

Can anyone please point me at the location of the breather filter, so I can check?



I had an oil and filter change about 100 miles prior to the incident.

Hi

Can you put up a few pictures of the engine

The sump breathing is just the small pipe that goes from the sump to the air intake

Malcolm,

What is your opinion?

I think that it is quite possible that a splodge of oil work its way up the breather into the intake.

When you are driving at a constant high speed any pressure or blockage could slowly work its way up.

Yes it sounds quite plausible to me

Thanks very much guys.

So it's just a breather tube/pipe with no filter?

Unlikely to reoccur, then, I hope.
