Found oil in cooling system
Hi,
I found some light oil in my coolant system and coolant reservoir. Oil is black in color. I thought it may had been a bad head gasket or cracked block so I took it in for a full test.
Compression Test: 210 210 205 205
Leak down Test: 5% 5% 8% 8%
Coolant Pressure Test: at 23psi, found no leaks.
The engine runs very strong for being a MY00 and barely burns any engine oil. We are both very confused to why there is oil in the coolant system and reservoir and my mechanic suggested it might be a defective factory oil cooler and have it tested.
Please share your suggestions.
Thanks!
