The car is a 1987 BMW 735i E32.
The head gasket was replace 1500 km ago with the head fully reconditioned,including new radiator with thermo fans. Since then we have had three radiator flushes, the last one had 150ltrs flushed through, and after only a few km of driving the overflow bottle fills with more oil than coolant.
This does not make sense to us as with good compression and CO2 tests, and no water to oil contamination, itís not the head. The car starts, runs fine, and does not overheat.
Does this engine have an oil cooler that could maybe causing this problem??
