1972 Oil fill cap?
On my small block valve covers, I was wondering if the oil fill cap was chrome painted or what?
Any pictures of OEM ones would be great too. Thanks. |

Re: 1972 Oil fill cap?
It should be a rubber oil fill cap. If you had power brakes then you also would have had the oil fill extension tube on the drivers side.
I don t believe the metal oil fill cap is original to our trucks. |

Re: 1972 Oil fill cap?
Although the extension is an add on. I have a metal cap near the fire wall. When the engine was replaced with a re-manufactured 350 long block, back in 1990, all the existing parts were re-used with the long block.

Re: 1972 Oil fill cap?
Certainly don't mean to mislead. My truck did not originally have the brake booster (i added it along w/ power steering and TH350 during a frame off this past year). I switched the valve covers which put the oil fill on the front right instead of the driver rear to allow more room. However, i don't have any reason to believe the fill cap isn't original as it was an unmodified family vehicle.

Rubber oil fill caps on my '72 C20 with a 350.
Does anyone know where to buy a new rubber oil fill cap that fits under the A/C bracket? |

Re: 1972 Oil fill cap?
According to my Chassis and Body Parts Catalog, the correct cap for 71-72 is part number 3980273, a push in oil cap, made of rubber. These are widely available in NOS form and reproduction. GM used these on lots of cars & trucks beginning in 1971.

The rubber cap is available in the HELP section of most parts stores.

Re: 1972 Oil fill cap?
Neither should I. Wasn't aware there were differences year to year.

Information regarding other years is great, but slightly off topic. |

Off topic? Maybe slightly. But, I think the info was relevant for future readers. Sorry if this caused any confusion. Does anyone know if the rubber caps were painted? I've seen them both ways. I'd think not since the oil tubes (when used) were black. Or, were the caps in the valve cover when the engine was painted and the tubes added later on the assembly line?
