[Farmall] F20 question

[birddog]

As I recall our 1938 F-20, John, the valves still depended on manual 
oiling through the spring loaded caps on the top of the cover.  1938 as 
far as I know was the last normal production year for F-20, although 
some were assembled in 1939.  The only other holes in the cover were for 
the primer cocks, also in the top.  These may have doubled as fasten 
downs for the valve cover.

Hope this helps.

Did later F20's have some arrangement to supply oil to the valves. The reason I'm asking is this.  The regulars and at least the early F20's depended on the operator loading oil into the wicks in the oiler trays through fittings in the covers.  We needed to replace the cover, it had rusted out sitting outside for who knows how long.  We wound up with two replacements. One with a dent and another in very good shape but with  extra drilled holes in it. They look as if they were set up for oil lines that ran up outside of the engine and perhaps flooded or dripped into the head area.
