Mike,
I have never actually seen a 16 or 20V-149, but I'm familiar with them on charts.
How did that 16V sound? I would love to hear one run.
Detroits have always been leakers. I use Conoco HD Fleet 40 in mine. Last time I bought a case, I believe it was about $2.25 a quart. Mine really doesn't leak that bad, altho I need to replace the valve cover gasket soon.
Bill
