There is a hole that goes up to the rear main bearing, then it has a drilled crankshaft that feeds the rods and other bearing. The oil does splash around from the rods to get on the cylinder walls. The oil then drains back from the bottom down to the engine oil pan. All compressors have this configuration.Ive looked thru the TM to try and understand how the stock compressor is fed oil. I couldn't find anything I felt was definitive, but it looks like there is an oil jet from the compressor bracket. They appear to be splash lubed. And a gravity drain back in bracket as well. I'll know more once I get it apart.
I forgot to mention that there is a metered orifice to the first bearing. Don't drill it out ! I made the mistake of doing this (for better performance) and ended up flooding the compressor with oil and dropping my engine oil pressure to boot !
