F150 Condensation in the engine?


Recommended Posts

Changed my oil in my 03 F150 last week and noticed on the bottom of the filler cap there was a milky substance that I'm sure is water mixing with the oil. It was just on the filler cap, the oil looked fine when I drained it and I'm not loosing any coolant in the system. I was talking to a buddy and he said that sometimes you can get condensation in there somewhere and that's where it's probably comming from. Has anyone seen this kind of thing before?

In my Hanes manual, for a lot of the fluid changes, it says to drive it for 20 miles so the fluid is hot and flows out better. I dont think I've drove that truck over 10 miles in the last 3 months. I got to go out to Cokato this weekend to work on the boat so I'll just keep an eye on the coolant level and if it doesnt go away after this weekend I suppose the next step is a compression check. I have to tow our 20' boat up to Kabetogama on opener, I was just hoping I wouldnt have to squeeze a head gasket replacement in there before then.

Thanks for the help guys.

The white milky stuff on the oil cap isnt anything to worry about in most cases. Now if there was white milky stuff coming out of the drain plug, then be worried! As they said, short trips do this. Also a bad pcv can do this as well, may not be a bad idea to blow $6 and put a new one in. But as you said you put alot of short trips on it, so most likely thats all it is from.

I hate to be the bearer of bad news, but if a couple miles at a shot is all you drive, you may want to take a quick peek at your exhaust, also. If you arn't heating it up enough to get the condensation out you may be looking at some exhaust replacement down the road. Stainless exhaust helps but it more expensive.

As stated, the milky stuff on the cap is no big deal. If it were milky white in the pan I'd be nervous.

Ya, 99.9% of the time this is a normal condition . I figure in your case is normal.

This time of year (winter months) with the extreme temp changes in the block, heads and other metal/plastic stuff inside the eng., condensation will occur. The filling cap is one of, if not the highest point inside of the eng. and does not see the constant bath of oil splashing around. This is why moisture builds up at the cap.

I see this more so on Chrysler products than Ford (due to the long neck on the oil filling point), but have seen on almost all engines at one point or another.

I thank you guys again for all your input. Glad, make that really glad, to hear this is common or at least isnt a major problem. I've been limited for the last 3 months on how much I can drive and that changes on Wednesday so at least I can get the vehicle out and on the road for more than just the drive to and from work. Like I said earlier, I've got to do a 50 mile trip this weekend out to Cokato so it should all burn up there. I take hwy 7 so it's 65 mph all the way from St. Bonni to Winstead. That should take care of it.

This is part of the reason the manufacturers recommend more frequent oil chages if you primarily drive short distances. The foam you are seeing is contamination and the filter may not be able to remove it efficiently.

Fortunaltly for me that was the only stage (except fines) since it wasnt a DUI. All I needed to do was pay $20 reinstatement fee and none of it would have happened, but I didnt even know my license was revoked, got pulled over, then got 90 days no license. I even showed the prosecutor the recipt that I paid my ticket on time, but didnt matter, "I should have known my license was revoked", even though they didnt send me a letter saying so. 2nd one in 2 years they dont have much sympathy. So a $100 speeding ticket turned into a $300 ticket and a 90 day suspension because I waited untill the last few days to pay the original ticket.

But anyway, fells good to be back on the road now. Thanks for the insight guys.

    • got this tackled today took about 3 hours to get both sides done. Didnt even get to use a torch....   Thought I was golden with just jacking it up and I could get to everything but no luck. Had to remove the entire axle hub and brake assembly to get to what I needed. Was a pain but still better then taking off the entire pivot arm.    Axle bearings were already greased and in great shape thankfully. Got both leaf springs installed and its ready for the road again.   Probably going to have my electric brakes checked, I am not touching anything with the brake drums. Based on what I saw it doesn't look like my electric brakes have been working anyway. Brakes are nice to have if its slippery out
    • By The way that didn't work either!! Screw it I'll just use the cellular. 
    • It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.
    • 😂 yea pretty amazing how b o o b i e s gets flagged, but they can't respond or tell me why I  can't get logged in here on my laptop but I can on my cellular  😪
    • I grilled some brats yesterday, maybe next weekend will the next round...  
    • You got word censored cuz you said        B o o b ies….. haha.   Yeah, no… grilling is on hiatus for a bit.
    • Chicken mine,  melded in Mccormick poultry seasoning for 24 hours.  Grill will get a break till the frigid temps go away!
    • we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.
