1938 1941 Buick Special Century Roadmaster Nos Oil Filler Cap 1304628 on 2040-parts.com

This fits:

• 1938 Buick Special, Century, Roadmaster and Limited (Series 40, 60, 80 and 90), with Regular air cleaner only (not Heavy Duty)
• 1941 Buick Special, Super, Century, Roadmaster and Limited (Series 40, 50, 60, 70 and 90), but only some (see below)

In 1941, Buick did some changing during the model year with their engines, partly due to compound carburetion, partly due to octane problems (war-time), etc. As a result, some engines are essentially a closed combustion/crankcase type, while some are vented. What that boils down to for this cap is that it resulted in Buick having to list a range of engine numbers in their parts catalogs where this cap, and some other engine parts were used.

This is the list of engine numbers for 1941 that this cap was used:

• Series 40 (Special) with single carb - before engine 4158776
• Series 40 (Special) with single carb - between engines 4158999 and 4173506
• Series 40 and 50 (Special and Super) with dual carb (compound carburetion) - after engine 4152147
• Series 60, 70 and 90 (Century, Roadmaster and Limited) - after engine 4120000 PLEASE LOOK AND READ. NICE SHAPE.
