exhaust design responsible for water in oil?

Further to last post, here is photo of exhaust. It was rebuilt last spring when prior version leaked at spring launch. Tried to replicate prior design.

Could this be responsible for water in oil? According to Moyer manual (chapter 7), design misses by a few points:
1) Water discharge fitting in hot section is not 4 inches below highest point of hot section
2) No anti-siphon valve installed at top of water output hose

Water could have been in oil by a slow start in spring with raw water thru-hull open. But want to also makes sure exhaust design passes muster if that could be culprit.

BTW, I did "thumb" compression check last week and all cylinders passed. A4 ran fine at haul-out and winterizing.

thanks as usual for all wisdom
