Identify this Engine

[achico]

Hi everyone,

I bought this 1975 Land Rover Series 3 88" diesel, but I see that it is not the original 2.5L diesel engine. Now, I would like to identify it to see the parts needed in the future such as: engine oil, gasket set, etc. I have tried to look for some photos of the model on the internet, but I have not found anything similar. Can anyone here help me identify this engine?

Attached engine photos, as reference.

Thank in advance!
