Wet rocker cover

Fetched off the rocker cover over the weekend and it was pretty
wet in there - more than just the usual bit of condensation.
Water trickled off the inside when I tipped it up. Lot of light
grey oil emulsion on the rockers. This is a new S3 head which
was fitted a few months ago, the old set up did not used to do
this. I'm sure there's not a serious problem, the sump oil is
fine and has been in there a long time. Rocker cover cork
gasket looks good and is properly fitted. I was thinking of
part-blocking the rocker breather with something like a sponge
or rag, so that it can breathe but hopefully not draw in water.
Anyone else seen this sort of thing and have any ideas?

Have you mainly been doing short runs? I had the same thing with
my 88" a few years back. I got somewhat concerned as it looked
like a lot of water and I'd convinced myself something was
knackered. A job came in that involved ragging the thing to
Clapham Junction Stn and back a couple of weekends on the trot,
decent long runs and it got properly hot. I checked again and
all trace of moisture had gone. 10 years on and this engine is
going strong in my 109" station wagon.

All my journeys are short, work trip is six miles each way. But
it was the same story with the previous head/cover and that
didn't wet itself. Maybe time to resurrect the old Kenlowe fan
- I was thinking about that to improve the mpg anyway!

Don't use a rag to block the breather. I did this once when I
lost the filler cap, six weeks later the oil light came on !
Investigation found that the engine
" breathing" had drawn fibres out of the rag and they had been
pulled to the suction filter that the oil pump draws from,
blocking it enough that the engine couldn't get enough oil to
create oil pressure.

Good point about the rag, thanks. It's a lot better now the
weather is drier so I have a while to think of a cunning plan...
