John,
There are rust inhibitors which are added to most antifreeze formulations
decrease corrosion in the water jackets and stabalize the antifreeze. These
do include silicates, phospates and borates. I don't know the amount in each
individual formulation of antifreeze, but I believe that these are added to
propylene antifreeze as well as the more toxic ethylene glycol. Also it is
suggested that antifreeze be diluted with tap water. The semi solids will
certainly cause bearing damage. The antifreeze causes the oil to sludge,
since it is not missiable--also the passages may clog with the thickened
mixture. There are acids produced by the phospates and borates, which will
accellerate corrosion.
If you have 1% antifreeze in the oil, there is a problem which needs immediate
fixing--and the oil needs to be drained, several cycles of oil run thru in
short order and then refilled.
Causes of antifreeze in the engine oil are ususally:
Defective or deteriorated seals, Blown head gaskets,Improperly torqued head
bolts, Thermally warped or cracked cylinder heads (from low coolant charge to
stuck thermostat), Cracked block or cylinder head from frozen coolant,
Improperly machined head and block surfaces , Corrosion damage of cylinder
liners, Cavitation erosion/corrosion of cylinder liners, Electrochemical
erosion, Damage or corroded cooler cores, Water pump seal failure and
weep-hole blockage.
If you have antifreeze in the oil,I would find the cause and get the oil
changed ASAP. 1% antifreeze in the oil is not doing the engine any
favors--should be zero.
