Heres two pictures of my oil cap:



The oil is about 1,000 miles old and the oil level was fine. Is this just condensation? I usually try and let my truck warm up in the morning for 10mins but I only have a 5min ride to work so the truck sometimes does not get up to operating temp because I shut her off. I'm just a little worried because I have never seen this much junk on the top of an oil cap that didn't have blown hgs. Trunk runs mint, doesn't blow smoke or show any signs of an hg issue.

Wow I dont know!

 

looks like someone had a good time in your oil cap....

 

holy crap, change your oil! you must have a ton of water in it.

what type of oil do you use?

 

i dunno.doesn't look good though.

 

Its napa oil which is made by the same company that makes Valvoline.

 

Ya either do I, lol. RIP Pimp C great rapper

 

weird. i would change it anyway.. is your coolant level low? maybe you have a bad head gasket...

 

Hi Dan..I was going to say come over here...Bryan LMMC-CT..

 

Ya I Checked Mine A Couple Of Days Ago And It Had A Little Bit Of That Milky **** But Damn Thats Alot

 

What does your oil look like on the dip stick? Is it milky?

I would try changing your oil again. Drain it into a clean container and see what it looks like.

 

that is what happins when you get moisture into your oil. It could have come from some sort of bad oil, or that means you have a blown head gasket that is pukeing cooltant into the oil.

before you change your oil again I would check to see if there is any coolant in the radiator/overflow tank.

 

Do you mean oil?

 

no, if there is a low coolant level that would indicate that it is being leaked into the motor.

 

I've seen this happen during winter months when you only drive short distances one way then park letting it cool off. The engine doesn't get hot enough to burn the moisture out. VW bugs's were really bad about it. You might also want to check your PCV system. Change out the oil and take it on a good drive to get it hot to burn off any remaning moisture.

 

Please delete....duplicate post.

 

I see this a lot at work during the winter months mostly on GM vehicles though

 

Yep, water in the oil and it could be condensation from not getting the engine hot enough to evaporate the water away. Watch your water level in the reservoir. If it is going down then you may have a blown head gasket.

I really suspect your engine isn't getting hot enough. You may have to use a cooling system heater in the winter. You can put one in the bottom radiator hose and keep it pluged in over night.

 

It could be condensation, thus water in your oil.
Normally when you have milky oil like that, it means you have a good sized amount of coolant in your oil, normally from a bad head gasket.
Change your oil. Like now. Use a quality oil, and yes motorcraft is good stuff.

If this continues, even in warmer weather....You need to get your head gasket changed!

And I completely agree with Ranger Carl above me

 

Have you had any over heating problems in the past? Just asking because..
My stepfather bought a 99 cadillac with the northstar engine, it ran hot, he put in regular antifreeze, instead of dex cool, it ran hot again, and his oil looks just like that. He has a cracked head gasket. Could've been cracked when he bought the car. I changed his oil and more than 3 gallons of the milky stuff came out! I had to add 6 or 7 quarts of oil and 2 gallons of antifreeze. The car still runs, but not like it's supposed to. When you do your oil change keep track of how much of the "milkshake" actually comes out. My advice, is to have an extra drain pan ready!

 

change the oil and oil filter. run it for about 5 min or so. let it cool down and change the oil and filter a second time. by doing this u should get most of the crap out and have fresh oil. run it for a day or 2 after the second oil change and check to see if it happens again. if it does, chances are u have a blown head gasket. also check ur collant level. that would be another sign that the oil and collant may be making contact with one another.

 

moisture.. i would do a motor flush and change oil

 

Holy **** i forgot mine was like this when i changed my oil! but like the rest said it must be water b/c i only have a 4 mile drive to work so my truck barely gets warm.

 

It has to be a blown headgasket....or could this also happen if your air intake sucked in some water? hummmm
