sorry but thats bollocks, chuck a cup of water on the floor, then add some oil...mix it around a bit, and see whats left when the water evaporates.....
if you mix water with oil it turns to white goo, if you then evaporate the water from it...it doent turn back to nice clean oil......you need to stop the oil being so heavily contaminated, so it DOESNT turn to goo...you will never stop it having some moisture in it when cold...
the point is, condensation is evaporated from the oil as it warms up,fact.......and this moisture always gets caught and held in the breather tank...dont forget,this is the tanks job right?seperating fluid from air.... this is where oil gets mixed with the most water,and where most contamination happens,small ammont of oil, fairly large ammount of water in comparison ......
run your car for 5mins, then remove and shake your breather tank....it WILL have water in it. infact,id edge bets on more water than oil after 5mins!
getting the tank as hot as possible as quickly as possible helps prevent condensation forming and being held in the TANK, a turbo can run at 600+ degrees,so the tank will get over 100degs easily(i have burns to prove it) and the condensation doesnt settle in the tank,or on the cooler tank walls,it goes out with the air....
it minimalises the water and oil contact,which is all you can try and do and it does work.... the first engine in my saff when stripped had alot and i mean alot! of white goo in the sump which was draining in from the breather return, so i did some testing, and played with position of tank ,and breathing position and the last strip after 50k miles...i had zero white goo, clean pipes....
alot of the better breather systems are mounted on the hot side of the engine
it will eventually burn off the moisture anyway, after a long riun... , but by then its contaminated more oil then if the tank never held the moisture that it does. over a period of time, this small ammount of oil contamination adds up, and end up with lots of goo...once its there it stays there..sitting in the sump
all imo ofcourse
and as for it effecting the cooling.....how exactly? the air breathes away to atmosphere...and how much oil do you think passes through a breather tank...enough to raise oil temp
