It is an interesting one. It has m44 style oil pan and timing case and m44 style oil filter housing with plastic cap. It also has blank boss for the rear crank position sensor.
Timing case has extra bolt hole around the oil pickup point.

I need to check the oil pump and see if it has a bigger one like the m44s do.

Everything else looks like standard m42.
