It does not look like an SD-22, SD-23, or SD 25.
It looks like a Maxima diesel engine minus 2 cylinders.
I think I need a head gasket for it as I am starting to see black specks and oil tendrils in the coolant.
The head and exhasut code are "W17". The block numbers are covered w/ grime.
I did search and cannot find anything about this, anyone?
