[TR] oil out breather?

[John Gillis]

Hi all, got my carbs back from Burlen after full re-build, very  
pleased BTW, fitted up and set up to run, I have noticed a drop in oil  
pressure which was 50psi at tick over, now down to about 15 when fully  
warm, looking around I noticed a very small pool of oil under the  
engine breather pipe, does this suggest any particular condition, this  
is an engine that has yet to go on the road, all running has been in  
the garage to date.
