[TR] oil out breather?

[CarlSereda at aol.com]

John,
Oil pressure at idle seems more normal at 15# than 50# and your oil drip at 
breather pipe - well, seems a little early to tell if a problem... (might 
always have a drip or two). I believe the way the internal engine air circulation 
works is air is sucked into top of motor thru gauze cap and blown (albeit 
slightly) down and out the side crankcase 'draft' tube.. I think the spinning 
crankshaft creates this vacuum and expelling action. At road speed the under-car 
draft also helps draw out crankcase gasses. I'd think you're bound to get a drip 
or two with the oil mist inside being so close to the draft tube. TR4 draft 
tubes are designed to minimize oil loss and have a little baffle inside - not 
sure about your earlier version.

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.
