Early GTO oil filler caps

[60sStuff]

1966 was the first year of the “Smog” unit on a car sold New in the state of California.

Option #616 (A.I.R.) is the #614 and #612 combined.
There were three model GTO’s built with the #616 option.
WV, WW, XE.

614 = Special PCV with sealed oil cap and hoses going to the base of the air cleaner.

612 = Air Injection Exhaust Control.

The two color photos show a complete working unit (WV = Tri-Power / 4 Spd.) of which 1550 were produced.
This rare GTO once belonged to my friend Grant Baber.

The black and white photo is a magazine test car “WV” with 3x2’s and #616 option.

The last photo shows another ‘66 GTO test car with a 4BBL. and #616 option.

A few ‘66 Car Billing History cards show the #616 box pertaining to the “WV” engine code.
