Can someone shed some light on reason my 71 Scout II 345ci`s oil pan has 2 drain plugs, one in the front and one in the back. Is there 2 oil pick ups dippin into each reservoir on the pan or what is the reasoning behind this configuration?
 
On a Scout II IH uses a different pan to clear the front axle. The pump lives above the small front bump out and the oil pickup extends back to the rear larger sump.
In order to fully drain the oil, some have two drain plugs.

This configuration is special to only the Scout II's and like bodied travelers.
 
The extra (front) plug was deleted on late scouts. Probably saved them 50 cents. If you ever have the pan off, it's not that difficult to weld in a cut-down nut for the plug that should have been there. Otherwise, you never get a true "drain" and about 1 1/2" quarts of dirty oil are left behind. Drilling pan.jpg

Don't forget the 1967-71 Scout 800, 800a & 800B with v8 as those also used the same oil pan configuration.
 
I have a 1973 jeep commando but the guy I bought it from put at 1971 IH engine in that has the dual drain oil pan. The front oil pan actually sits right on top of the front axel and got cracked after I hit a pot hole when the hot each other. Does anyone know if they make a single drain that would work for this engine without the front compartment?

Original engine was likely an AMC 304 V8, which has a rear sump oil pan and the oil pump is outside of the pan. Interesting choice by the PO to go with an IH SV8 in it's place. Could he have been under the mistaken impression that the AMC 304 and the IH 304 were the same? If so, he eventually discovered that they aren't. That's been a common misconception over the years. The Scout engine bay is very shallow in comparison to the Commando engine bay.
