RE: Overshot's Blog - T680 - 08-23-2016
Imo is not a coolant leak inside the engine.....you must show boron,sodium and potassium...yes all three for a coolant in oil
Mr lee you are using delo15w-40 this oil has the highest 557ppm boron count since new ...absolute highest of all ((rotela 42ppm, delvac 73))
Yes boron is in most antifreeze but is used in the oils as additive
Delo has <5 ppm counts of potassium in the oil but is an additive in gear oil too, yours is not very high
Delo has <5 ppm of sodium in oil already
Are using gear oil????
Aluminum is found in Pistons,bearings and pumps ...so maybe your coolant pump is going downhill!!!!
Dell has 3ppm aluminum already....highest
And the TBN is the lowest of all big 3 oil ...only 8.86....((((delvac 11.0, rotela 10.6))
The TBN is not supposed to be left to drop more Than 1/2 of it since new before changing oil
So theoretically u must change the oil sooner than 17k miles...

T680 I use delo
RE: Overshot's Blog - Mr Hagg - 08-24-2016
T680How can the coolant pump be a problem. Oil is in no way around the water pump for it is external pump belt driven.... Unlike cat or detroit or even volvo.

That îs right mr.hagg.....

Great results. How many miles on this oil? What are zinc readings?
RE: Overshot's Blog - T680 - 08-24-2016
Oil 10 k
Engine 301 k
Zinc 1287 soot<.1,
Ceck ((abc of oil analysis, at http://www.thedieselstop.com
They say that for coolant in oil must have boron,sodium and potassium high readings
For bearing problems must see cooper,tin and lead high

Solubles, is that soot?
