Distributor Cap Hole Plug

[chrysler1941]

What’s this hole in the distributor cap for? There's a rubber plug for it, 8-27-75

I can’t imagine it’s for setting dwell?

marine engines had a hole in the cap to vent it. the hole is not needed for automotive application. lots of Chrysler engines were used in boats.      capt den

What about army and air force engines?

And all those National Guard engines.

Apparently the army, Air Force and national guar don't need as much venting as the Marines do.  ... No mention of the Navy.⚓️

The Army and probably all branches of the Military had engines designed to run completely submerged under water used to ford rivers, rice paddy's and such. Doubtful they had vented distributor caps.

I know submarines have engines in them that are designed to run completely submerged, the trick there is to keep all the hatches closed.

And have lots and lots of compressed air.

I spent 7 years in the Submarine Service, but never saw an engine that could run underwater. We always had to have the snorkel mast up so the engine could get fresh air from above the surface. The snorkel mast had a valve that closed if water covered the mast, when that happened the engine would suck all the air out of the boat in a heartbeat. Big diesels need a lot of air.

   Navy engines run just fine, thank you very much. As for the Marines, we gave them a ride whenever they needed it, and to wherever they wanted to go. And, when they were done, we were there to bring them back home. Obviously, I’m a Navy vet, and I have a lot of very high regard for my Marine partners. To quote them: “Semper Fidelis” – “Always Faithful”. ‘Nuff said!!!

[Niel Hoback]

So, I would be safe calling my old Plymouth "Semper Fidelis" as its always been faithful.

   Being a Navy vet, that doesn’t pose a problem for me. But, just to be on the safe side, you may want to check with a Marine – he may take exception to it, and then again – maybe not. Thx.

  It's obvious to me that it would be an insult to every Marine.  I was just saying how dependable the old car is for me. Merely a comparison of reliability. 

  I apologize to any and all service men and women for any perceived inference that any car could be described as worthy of the honor of any member of our armed forces .
