Dave, The can only has 2 lines that enter at the top. As you observed one comes from the valve cover. The other goes to the original port on the side of the air intake. The 2 hoses that appear to be coming from the bottom are engine raw water running to a loop seal which is mounted on the wall behind the oil canister.

I see the line running from the valve cover to your new canister. There are two other lines attached to the canister. The one on the bottom I am presuming is a drain. Where does the other one go? Is it just open toward the bottom of the engine?

Some oil carry over is normal and a brillow paf style if separator can usually be found at the valve cover where the tube attaches. Excessive blow by is indicative of stuck, worn, or broken rings or other internal problems. I have no idea what the PO's maintenance practices were or what oil he used. What I do know is that I got stuck rings the very first season I owned the boat. I successfully unstuck them but had a similarly wet air filter as you described. I installed a blow by canaster to monitor and catch the oil instead of soaking the air filter. It allows me to monitor the amount of blow by oil too. I've been using Amsoil diesel oil since and in recent years have noticed a considerable decrease in the amount of oil accumulated. You can see the canister in this video. https://youtu.be/H-GI38vE4hQ And you can buy one here. https://www.amazon.com/dp/B01JQAJY9W/ref=cm_sw_r_cp_apa_4Qw3AbJ0ZVY8W Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Sun, Apr 22, 2018, 10:24 PM David Knecht via CnC-List < cnc-list@cnc-list.com> wrote: > I removed the air filter holder from my engine today to check on whether > it needed cleaning and was surprised to find the filter soaked in oil and a > significant amount of oil inside the housing.
