My 8/71 240z has its original oil pan which is in good shape.   I just got my hands on a early oil pan which is supposed to have more capacity. Is this true? I think I read somewhere they had issues with the oil pans

Not familiar with capacities changing or problems with the oil pan itself. Where did you receive that information? 

I dont remember thats way Im asking. Could not find it again on the net.

This is old so the link to zhome is no good but we have the guy that wrote it, @Carl Beck might have time to respond.

 

Indeed the early oil pans are different; the drain plug location and a 'reinforcement' plate on the side of the pan.  I am not aware of any capacity differences.  My service manual lists engine oil capacity of 5 liters or 1.3 US gallons.  My parts manual list a part number change around 5/71.

Thank you 26th-z That was the big thing the reinforcement plate. Like your Gurney for president button. Got to meet him at the shop in Santa ana . Great person and driver

My oil pans are from real early cars, of course.  I don't recall seeing them on late 70 models.  The "issue" was with the crankshaft of L24 engines.  Technical Bulletin TS70-28 of 8-21-70 notes the crankshaft change beginning with engine serial number L24-3607.  I understand that the engine vibrations caused cracks in the oil pan otherwise I have no explanation for the "patch".  Notice that it has a notched hole in the side face.  No idea why.

I met Dan a couple of times in Daytona.

My 7/70, engine number L24-010178, came with one of the the brazed oil pans.

 No brazing on my 10/70 pan.
