1928 Oil Pan
 

I have a 1930 engine in my 1931 Mail Truck with its standard oil pan. I gave an excellent 1928 oil pan with its large flange drain hole. Wondering if using the 28 pan would be advantageous regarding oil changes, cleaning gunk, better access. Also, wondering if there was a reason other than manufacturing cost for changing to the small plug pan? The Mail Truck will always be my driver so I’ll use which ever pan makes its maintenance better/easier. Thanks for any advice!

If the engine is clean inside and you use detergent oil and service it regularly I see no advantage in replacing the existing pan.

Yes, but its a valid question - what if you have not been using detergent oil? Would it enable cleaning of the sump without removing the pan?

Re: 1928 Oil Pan
 

If offers marginal help in cleaning as it is still too small to get your hand in there to ensure all the sludge is gone. Another draw back is the cork gasket for the access cover is prone to drip and weep as it is trying to hold back the entire contents of the oil pan.
As was said if you are using a detergent oil and changing on a regular program, you shouldn't need to get it there that often.

That's kinda what we ran into with our Sept. build '28 Roadster. I think the post 1928 oil pans with the small drain plug are fine. If you're running a clean engine and modern detergent motor oil it seems to work out well.

On our 59AB Flattie, with that gargantuan oil drain plug you have to use a spanner wrench to change, there is enough room to stick your fingers in and feel along the bottom of the pan near the drain plug opening. Since running Motorcraft semi synthetic oils each year that engine is clean as a whistle (blower??) inside:p:p

The circular lip surrounding the oil pump access plate is raised high enough that, in my observation, the early pan will not allow as complete oil and contaminate draining as the later pans.

Thanks for the great advice. Think I’ll stick with the later pan. Using quality oil and changing annually or 500 miles.

I can fit my hand inside!
Cleaned out much sludge that way.

Giant peoples results may vary.

Re: 1928 Oil Pan
 

The dipper tray has baffles, so the pan needs to be removed to clean ALL the sludge, no matter which pan you use.

I agree !
