Condisation build up? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is anyone using the Chrome push in Valve cover breathers? If so are you guys getting milky build up under them? My truck isn't going threw any coolant but for some reason on both Breathers and under my Oil cap is has Water build up like it has blown head gaskets? The driver side is the worst I can take it off and shake it and actually get small amount of water to come out of it. you can kinda of see the Breathers in the pic please ignore the dirty engine bay it is now clean and organized.

A little bit is normal I think, while quite a bit is obviously bad.

Off topic- if you want to bring your tiny air cleaner with you on Friday, I've got a brand new large shiny one I'll swap you...

Cool thanks Brad and LOL I hope the small one will be coming with me as the whole truck will be there

It’s been a long time since I’ve seen this problem mainly in older engines prior to PCV valves being used by car manufactures and living in a high humidity area.
I would recommend installing a PCV valve.
Also you should pull one of your valve covers and see if you have a milky white gunk on the inside. Then you might consider using an engine flush if the engine does not have a lot of miles on it to get any gunky stuff out of the engine. Be warned if you use an engine flush on a engine that has a lot of miles on it you could start burning oil and be looking at needing a engine rebuild.

condensation milkey stuff building up to heavy sludge residue is normal for breather systems // a PVC system was designed expressly to eliminate that problem

This might sound stupid but i had this problem and i changed what brand of oil i was using,

Do you bring your truck up to operating temp and run it for awhile? Or, do you just take short trips, barely coming up to operating temp? Try the PCV mentioned earlier, and if you just take short trips, run it awhile to heat it up to burn out the moisture in the engine.

Has the outside temperature dropped? This could be a contributing factor in condensing any water/particulate out of the oil.
