Early 240z oil pans

[billgtp]

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.

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.
