Pulled the valve cover

There was nothing there a week ago when I pulled the sample

You pulled the sample from the bottom? Was the oil ambient temperature or was it warm when you took the sample?

 

[BigPapa]

Water and coolant would have been on the bottom.

This is why I prefer to use a lab that tests for coolant. That report wasnt even flagged.

Not necessary if you know how to read a report. High sodium and potassium with water. Pretty obvious. Monitor isn't the only labs that don't list coolant.

 

[JR]

He doesn't have high potassium or sodium levels. That's already been established. Remember, my levels have been higher, with zero water or glycol?
Those aren't high numbers at all. I don't know why your fixed on that.

Water is tested using a solution of alcohol and iodine and reacts much differently than glycol, it's not an accurate method to use to determine antifreeze.

 

[JR]

Here is another tid bit. Anything under .1% for water is acceptable. .1 - .2% is flagged as a caution. The acceptable range for coolant is zero. .1 to .2% coolant is considered critical levels of contamination. Big difference. They both should be accounted for in a test otherwise your just guessing as to what is going on. In his case he tested .2% water - IF that's coolant showing up that should have been an immediate red flag with the recommendation to drop the oil before operating anymore.

 

[SAndreasen]

Well we can argue until Christmas about the numbers . The fact is the engine has a knock in it pretty sure it’s a rod knock . When I pulled the oil sample a week ago there was no antifreeze that came out just oil . Today there was a good half a gallon of straight antifreeze that came so green you could have reused it then oil engine oil and antifreeze

 

[JR]

That's why I asked how you took the sample. If the oil was still hot when you pulled the sample the coolant may have been mixed in well enough you didn't notice it.
When you shut the truck off and the coolant has a chance to separate from the oil is when you will see what you witnessed.

No, I don't believe it has been established. The levels you reported are high also, but not as high as his. Remember, there is only 5000 miles on that oil. I'm fixed on that for two reasons. One is a comparison to my reports and two is the advice from a fleet owner who has looked at hundreds of oil analysis reports. The presence of both elements indicate coolant. One or the other contaminate is usually road salt. The water was a bonus. Normally it has evaporated.

 

[JR]

Different engines, different oils. Those two numbers mean little by themselves with only one test and no history.
FWIW, the 2ppm difference between my 4 samples and his sample is a wash. If the oil company thought they were abnormally high shame on them for not flagging them.
I suppose we will have to agree to disagree.

 

[GAmes]

I can't tell you how many different brands of oil I have used. I use what is on sale, from Wally World Super Tech to Valvoline 5W-40 synthetic. My highest reading in 20 different samples ranging from 5000 miles to 30,000 miles was a sodium 9/potassium was 1. They, along with silicon, are listed as contaminates. Therefore, IMO the engine type and oil type means little. Air filtration on the other hand could explain the silicon of 15 in the OP's sample. My numbers are always below 10.

the strange thing is I took the sample cold the truck hadn’t been started in about a week and the oil was black as black . Now the truck has probably sat two weeks and magically there is that much antifreeze in it ?

Maybe whatever let go punched a hole internally and its been leaking ever since?

Pulled the sample cold engine hadn’t been ran for a week or so that’s the thing I can’t get

Anything is possible
