Oil analysis tells me theres coolant in it????

Well I think that I will be replacing the head gasket sooner than I thought.



Heres the results from Blackstone



Aluminum 6

Chromium 2

Iron 23

Copper 39

Lead 6

Tin 1

Molybdenum 84

Nickel 1

Manganese 1

Silver 0

Titanium 0

Potassium 4

Boron 107

Silicon 8

Sodium 22

Calcium 2834

Magnesium 15

Phosphorus 1123

Zinc 1654

Barium 1



Properties



SUS Viscosity 73. 0

Flashpoint 495

fuel less than . 5

Antifreeze ?

Water 0

Insolubles 0. 5



So why is the copper and sodium so high?? Anyone else expierence similar results??



I am glad the spare head is already on its way to the machine shop.



Also what gasket should I use. (Stock, 10 thou copper, 20 thou copper??)Boost will be around 50 - 60 psi with the twins.



The highest its seen to date is 45 psi w/water meth.

Copper

I recently had my copper jump up from the last oil sample. I think it went from like 30 to 70 ppm. My oil had 16k on it at that sample so I changed it. The lab stated that due to my low overall miles (37k on truck) that is was probably normal break in copper from seals, gaskets etc. I hope this is it. We'll see in another 5k when I sample my new oil again to see whats going on.



Dont know about the sodium, mine was low. OAI lists sodium as a contaiminat (Duh) from engine coolant or an oil additve, but thats all they say.



Hope this helps

Make sure you sample again before tearing into it. There's always faulty tests here and there, samples can be contaminated and such; happens in any kind of field that uses lab work. It's a long shot but it's cheap and will either validate or contratict the previous sample.

I'm planning a . 020" marine gasket w/ o-rings. Strickland runs 80+ w/ o-ring and 12mm studs. good 'nuff for me!



I wouldn't run copper on a truck that's going to see more street miles than track miles!

oh yeah, I don't think the 24v's can run thicker gaskets without issues with injector/piston bowl alignment due to the injector angle!
