QSM11 Oil Fill Cap

[Robert Connolly]

Was offshore a few day ago in fairly rough conditions. Noticed the Oil PSI in my Port engine was fluctuating abnormally. Shut it down and checked the dipstick to find I was at least 2 gallons short and had significant oil in my bilge. No leak on the inboard side so I made my way to the outboard side and immediately saw that the Oil fill cap on that side was on the floor and oil had blown all over. I assumed it wasn’t tight and came off due to the rough seas, but I was reading that a fill cap would be sucked down tight while an engine was running. The article mentioned CCV blockage and/or significant engine wear as possible culprits. I changed the CCV filters this year, and the engine has only 1,100 hours and runs great. Am I being paranoid? Should I just put more oil in and crank the fill caps tighter and check them more often? Thanks – Rob

They look about normal to what I typiaclly see when installed per  the Racor/factory” set-up..

Tony any comments on the CCV pictures?

Thanks

[Robert Connolly]

That’s the type I have Clark

They still tighten down really well. I can’t even pull them off when they are cranked down tight.

CCV Pictures

I changed the CCV filters in August 2020 at 900 hours. Engines now have 1,100 hours. The filter on the left of the photo is the one from the engine that the oil fill cap came off of. Previously, I could find no record of the CCV filters having ever been changed. Doesn’t mean they weren’t, but it’s not in the engine maintenance record that was left to me by the previous owner.

Rubber expansion caps?     The type you turn a T handle and as it tightens the rubber ring expands and jams itself in the opening you are trying to seal?

 

I have a couple of those on my much older engine.    As the rubber shrinks I have added either an extra LOOSE nut, + a washer either side  or a stack of washers to expand the rubber ring more.   The result is the ring grabs properly.

Thanks Tony

I will do all as you stated. Up here in the Northeast, it’s winterizing time, so this week I have done the oil changes and winterization. I do have the rubber expansion caps. Is there another option?

Spend more time in your engine room–clean up the mess until all is 100% spic & span.. If you have the “rubber” expansion caps, wipe them dry and the tube where they go dry before tightening them..

Add oil as needed, but keep it at the low end of the correct oil pan capacity amount.

AS to your Racor CCV’s?? See is they are totally “saturated” again Post good pics.
