Hi All,
Ihave been noticing a little blue smoke after long periods of idle also when the engine is under load. I have checked the cylinder compression which is ok, i have checked the cam breather pipe that goes to the intake pipe and noticed that there is oil in there.
my understanding there should be a crank case breather too which could potentially need cleaning however i havent got a clue wher to look.
anyone got any ideas where this pipe could be located?
I have a 156 1.8 CF2 engine

many thanks in advance

could it be possibe that the valve stem oil seals are shot?

Hi, I posted a thread a couple of days ago. I cleaned out the vapour separator located inside the cam cover on a CF1 engine. It was solid with gunge. I can only assume that it created a sort of vacuum holding the oil in the cam housing and not letting it drain back to the sump quickly enough. After cleaning there is now no oil coming out of the breather pipe. Hopefully this will help with emissions as there is less getting fed back into the engine. Not sure if this helps but it cost nothing to fix. I have an oil catch tank fitted also, sort of belt and braces job.

Any pics and details of the oil catch can?
