Is your question around the oil piping coming from such a sandwich plate fouling the A/C compressor?
Yes. I discovered the remote oil filter is an Earl's kit that can be seen in this picture.
And again here

I would like very much to fit the standard SW20 Air conditioning compressor to this new Gen 2 engine and can see that the dump pipe may be another issue.
So next question "Is anyone running air cond with a after market dump pipe"
Main reason I want the compressor is to experiment with getting intake temps down and doing away with an intercooler.
