... so here's the deal. I've had the SS boat out a couple times and both times ended up with more moisture in the valve covers/heads than I'm used to seeing. I didn't build the motor, but did pull the pan/intake and look everything over before I ran it. No traces of water in it and it looks to be a very nicely built motor. All I did was add a water pump and put it back together.
After the first time out, I saw a lot of moisture in the valve covers so I thought maybe I screwed up the intake gasket. I pulled the intake off and checked everything again. Didn't look like it was leaking so I put it back togehter. We tested the boat again over the weekend and after 2 10 lap sessions, pulled the valve cover and again quite a bit of moisture in the head/valve cover. The oil filter is clear and no water or water/oil mixture in the pan either time.
I've never seen this much condensation without a problem, but also never tested in 55* air with about 70% RH and 40* water through the oil cooler/engine. FWIW, Bubbletop ran his boat the same day and he didn't have as much moisture as I did, but more than he's used too. I'm thinking of testing again, but bypassing the water around oil cooler and maybe even pulling the water pump off to get more heat in the oil. Anything else I should look at or am I being unusually parnoid about this?? Appreciate any input.
