Is this water in my engine? Pictures inside

I noticed this awhile ago when I pulled my PCV valve to reconnect it and noticed it had a bunch of white stuff on it.I wrote it off as just lithium grease the engine was assembled with or some water from condensation on the alluminum valve covers. I changed my oil and it didnt have anything in it as far as gray bubbles or white. I pulled both of my valve covers and they are covered inside with this my rockers and everything dont have any of the white stuff on it? What is it? Is it my head gasket blowing out?
I included pictures of the head the valve covers and my breather.

are you ever missing water from the radiator?

if not then chalk it up to cold weather short trip driving and not getting the engine hot for long enough

if missing water then you may have a bad intake or head gasket issue

does it overheat ever?

over 195 or 200 ever ?

if so then a problem somewhere

also see if any air bubbles rise up into the tank or rad while running

if so then you got a gasket blown somewhere, usually head gasket does this,

big bubbles a couple every couple seconds, and usually overheating also

It`s common for the top of the valve covers to collect moisture due to condesation, especially on a new build or when weather conditions are favorable. If the oil in the engine isn`t milky then there`s no problem.

What is the Thermostat temp? In winter, it might be necessary to run the engine 190-205 or more to bake it out Depending on whether you drive long enough and far enough to get the oil good and hot. Here in the damp and cool Northwest, it takes my 350 at least 15 miles before the engine oil temp gets up to 180-190 degrees, it takes the cooling system about 4 miles to get there. So there is a significant lag in cold weather before the oil gets hot enough just to cook the condensation water out of it.

Aluminum valve covers run too cold; fine in the south east or west but not where its damp and cold. This looks typical of an engine that doesn't get hot enough to bake the condensation out. To that, add the possibility the crankcase is insufficiently vented.

While this could be the result of, or at least augmented by a minor cooling system leak into the engine, don't forget that the largest product of combustion, thus is present in blow-by, is water. Ha, I'll bet you thought Al Gore said it was CO2. Well he probably did, but no it's H2O.

Given long enough, this is what becomes sludge. It'll also form acidic compounds that can damage bearings and cause general corrosion/rust.

IMHO, if you can't avoid the type of driving that contributes to this, increase the frequency of your oil/filter changes.

oh yes PCV system good point there cobalt sir.,

is the PCV system connected properly and the valve in good shape not clogged or anything ?

make sure

needa a good clear filtered return on one side of the engine and the PCV valve connected to a strong intake manifold source on the other side of the engine

to cross ventilate and keep the crankcase clear of vapors including water moisture

or it will build up inside the crankcase and let water soak into and mix with the oil, and mess with the bearings, and so forth over time, and slowly shorten the engine's life

That does look a lot like an oil filter- but it's a breather.
