I ran the engine for 30 min at idle and drain the crankcase again. When it was draining out I was able see a layer of tranny fluid on top of engine oil coming out . I think it was a good idea to drain the engine again. Anyways thanks for the replys, but I really look forward to head gasket change
. BTW my aunt doesn't take care of her cars. Sometimes she goes 9000miles on fossil oil, so I doubt this car was well maintained
