Oil breather hose

the motor should be briken in by now unless you put synthetic oil in it right off the bat. yes turning the filler up will stop it from driping, I doubt he used total seal rings in it they seal real well for a very long time. as for the neck it may have a gasket ,but I replace the gasket with a big "O" ring.are the valve covers vented? it may need extra venting, a small vent hose will push oil up through it where as a big one will not, or 3 smaller ones usualy wont. I use 2 , 1/2" vents coming off the valve cover tops going up to vent filters. I have the angled filler neck, much easyer to fill.

A 1915 should have a good breather system; is your car equipped with one? I believe you should get the valve covers vented, etc. This is what I have on my 1915 and it works like a charm:

By the way; if I remember correctly 600 miles was the mileage where a new motor was deemed as broken in.

well that old berg unit is pricey & not a good idea to interduce oil mist/fumes into the combustion chambers, I just finished a motor with that on it, it still has a single hose.I wasent impressed with it.neither was the owner as it had to have some mods done to it befor it would work on his bus,I dont know why I didnt do that part.& just vent off my valve covers.yes the oring may let you turn it farther, or you may put a 45 or 90 degree fitting in it aimed up, it,s just 1/4 pipe thread.brass, stainless steel aluminum or even plastic fitting,( I have plastic fittings in my valve covers) the mettell ones you can drill out farther so they have less restriction, mine are 3/8 pipe so there biger any way& I have 2 of them.

TDR,

You should be able to take your fitting to just about any hardware store or even an auto parts store and get a 90 degree fitting as the threads on the fitting are most likely regular pipe (NPT) thread.
