Title: Crank case breathing? Post by: Angle Grinder on 04 December, 2012, 02:21:44 PM My Flavia is now in winter hibernation so I am tackling a few jobs that I've been outing off, so....
The oil filler tube has a rubber pipe running into the air box for the Carb, but is there anything "clever" in the crank case breathing on a Flavia that I should consider servicing? For example a PCV valve that might need testing or a gauze filter to trap oil droplets that might need cleaning? Title: Re: Crank case breathing?

If cleaned due to heavy deposits I would reoil!!

On a Fulvia you can sometimes spot the telltale brown deposit at the bottom of the breather tube, indicating nasty bits of rotten brillo-pad working their way into the sump ......
I think I did every Fulvia I that I had over the years, so at least 5 or 6 and they were all rusty to some extent or another I wrote an amateur's guide to repairing them a few years ago which was published in Viva Lancia (I am sure someone can find a ref. to this if required - I can't remember, but about 10 yrs ago !)

Unlike all later Fulvias my 2c never had this fitted, just an open to the atmosphere breather pipe, If I remember correctly the wire mesh was replaced by a stainless steel pot scourer?

Post by: lancialulu on 07 December, 2012, 04:10:26 PM Its differently organised on a Fulvia - the mesh is in a pot that gets all the condensation from short runs and when it rots (I havent seen it on my Fulvias but did change every one for stainless mess as a precaution) it drops into the crank case.
I think the lttle mesh on the Flavia is in the breather hose between the oil filler and the air box. Still a potential problem but less worrying. Tim |
