Yellow liquid inside oil cap?

Hey guys. I'm changing my oil here today and I went to fill the spout with the new oil and there is yellow liquid in the oil cap and a little at the end of the spout. It's the same consistency as oil maybe a little thinner. What the heck is it? I've babied it so I doubt it's coolant in the oil but everything possible right? Thanks in advance.

 

Motor puss...lol just condensation

 

Normal. Don't worry about it.

 

I've seen it changing the oil on a lot of tundras. I think it's just water and moisture getting inside the cap. I could be wrong though.

 

Little bit of moisture mixed with oil. My 4runner had it for a little while (shortly after the break in period) then it went away.

 

Moisture collecting inside the engine from the atmosphere. As long as you wipe it out when you do the oil changes, you're good. Some oils are better at ridding moisture content than others, Royal Purple is probably the best at doing that, and Mobil 1 does well also.

 

condensation from the short plastic tube section.. actually yours looks pretty good

I believe that would be Tacoma jiz!! lmao hahaha

 

Hey OP...I had the same thing and did the same thing u did with the pic...totally normal as everyone has already informed. Have a good one.

 

I usually find a little under the filler cap when I change the oil. Just a little moisture, I clean it out, no problem.

 

Moisture in engine from not enough long drives at full temp. Take longer drives occasionally. Can also happen if antifreeze leaks in, but I think oil would be milky if it was.

 

Thanks for the fast replies guys! Good to know it's normal! I thought Betty had a yeast infection.

 

Normal

 

X2, longer drives.

 

Mine has it too...no worries I think!!!
