I have a 230 flathead for a 1955 truck c3
I'm looking at a resovior on top that is round and do not know what it is for.

Can you help a dummy

OIl filter?

Round things around a 230 engine would be:
1) Oil fill cap (just slides over the fill tube
2) Air cleaner (On top of carb with a wing nut when it left factory0
3) Oil filter (Beside the engine with two oil lines coming to it. Bolt holding cap onto a canister)
4) Power steering reservoir (Just behind belt driven pulley) two hoses going to the pump itself
