Hi Tom,

Attached photos of the info on the valve after I chalked it up:

Donaldson Crankcase Ventilator
Take apart every 250 hrs or 10,000 miles
Wash in varnish (remover?)
Install arrow up
Donaldson (Mfg?)
St Paul (MN?)
Made in USA
US, Can, Br patents
Part No. V4 15

As an aside, Williamsburg VA? I spent 2 years in Newport News at the drydock 1969-70. I was there at the building of the USS Nimitz and the repair to the USS Enterprise after the tragic hanger deck fire. Really loved VA but wound up on the other side of the world.

Cheers,
