oil in collant even after oil cooler change BMN 170 tdi
2008 BMN 170 tdi engine
i had oil in my coolant bottle so i changed the oil cooler, flushed the system quite a few times. every day after doing my daily 70 mile trip i would remove the bottle and clean it. decided to leave it for 3 days without cleaning it and the coolant light came up again. checked the bottle and there was oil in it again. what else could it be, head gasket? ive got no other signs of a head gasket thats gone. no trouble starting it in the morning and definetly no oil getting into the engine at all. everything ive read up on the BMN engines with coolant and oil mixing is a failed oil cooler and alot of failures in the head cracking causing coolant loss but im gaining oil not loosing coolant.
