Hey everybody I'm new here and in need of some guidance. I found an '87 6.9idi with 180K miles on it. The owner says that it has been bubbling coolant in the reservoir tank. He says it doesn't matter how long the truck runs for (meaning hot or cold it will do this) and says that the pressure only lasts 10 to 20 seconds then stops.
He is guessing head gasket or head. I am guessing head gasket, but my knowledge is limited.
I'm just concerned that it could be cavitation. How likely do you guys think that would be? I know the 7.3 was prone to cavitation, but was always under the impression it was less likely with the 6.9.
Please let me know what you think!
Thanks,
Sam
