Ok guys,
I know this topic is a little redundant and for that I apologize. After a great weekend in Laughlin/Mohave I decided to take one more run from Davis dam down to Harrahs and back several times. Always fun to make a few early morning speed runs to make sure the folks at the Davis campground aren't sleeping to late. The unfortunate part is when I was putting the boat back on the trailer I noticed some milkshake coming out of the breather and around the dipstick. Upon pulling the valve covers I discovered more milkshake. I'm running a BBF 472 OT headers Berk pump in my 18' Dimarco. I'm running the gate valve basset tee setup. I know some of you guys are going to suggest the Ford is my biggest problem but cut me some slack I just milked my motor. Boat ran great oil pressure good temp good plugs all look good. There was absolutely no indication of a problem other then the milkshake. Inside of valve cover were thoroughly coated with white milky shit not so much however on the dipstick,some evidence of water just not the white stuff. I'm familiar with the Ford timing cover issue as I had to replace it once and it seemed to take care of problem. The boat had been garaged for 5 years prior to this trip so maybe a gasket issue? Thing is everything was fine until that last hour long river run. Anyway totally bummed so I'm trying to get a punch list together so I can start digging in to diagnose and fix. Thanks

compression and leak down test

Depending on your cam. Fords are notorious for sucking water out of the headers with the overlap of the big ford cams I run a 666 lift custom ground cam and use a ball valve and jet inserts on my header water lines and that fixed my problem. Also remember that the BB fords do not take Kindly to high water pressure and leak water into the oil via timing cover . Ideal water pressure on a ford is around 14psi

Put your pressure gauge inline with your gate valve from your pump. This will give u correct pressure to you motor up to 16 psi.

If the oil is not wet in the pan (banana goo) like mobboss stated then I don't think you have an actual problem.

A little bit of baboon poo in the valve cover area is fairly common if the oil is not allowed to heat up enough to boil the moisture back out of the oil. You oil temps really need to be in the low 200*F range.

I also agree with Ralph that a good baseline compression and leak down should be in order.

Looking at your picture, I am not so sure you have a major issue...

Agree.

You have to figure, the engine is running in a high moisture area with low running temperatures. Every time you turn the engine off and it "cools" it draws in surrounding moisture and the condensation will form like what you have. I have fought similar conditions WITH engines throughout the years and have learned that some do it, some don't, and to just keep an eye on engine oil level/condition.

Water in valve covers with no increase in oil level. Run it. If it's filling up the pan, you got a problem.
