[QUOTE=Gilles;631655]Bad O-rings on the he heat exchanger could be a cause then, right?

NO. This is physically not possible. 4 O-rings that contain pressures greater than atmospheric (oil at 15-50 psi and coolant at ~18 psi), cannot leak into each other separated by 2+ inches through the atmosphere @0 psi (14 psia) unless the O rings were gone and the leak was so bad they drained into the other from residual on the engine. But then I think the fluid on the ground would be hard to not notice.


Edit If I ruined a long standing joke like foglights then I apologize.
