M104, oil in cooling system strange problem....
Few weeks ago, i found oil in cooling system. OK. Head Gasket.
I removed head, gave to workshop. They resurfaced it, replaced valve seals and checked valves... Everything was OK.
I bought new head gasket (Elring) and head bolts. I assembled everything (bolts was screw accurately, sequence and torque) , everything was ok, engine run accurately.
I cleaned cooling system, but oil still get through cooling system. Liter per 500 km... I also check Oil cooler in oil filter mount and its ok, no leaks.
Any one have a idea ? Broken head ? There's no leaks to outsite of engine or to cylinders, no liquid coolant on oil, no compression leaks to cooling system.... Only oil on liquid coolant...
(sorry for my bad English...)
