Hi,
Sorry to repost but thought that I should mention in the title that the
car is a Subaru.
I have a 1999 Subaru Outback with ~81000 miles. On a recent trip the
engine temperature started to fluctuate between overheat (top of the
gage) and normal every few minutes. I found the oil level down 2 quarts
which I added and the coolant overflow tank almost empty; I added water.
I then drove car about 20 miles before getting it towed to a Subaru
dealer. They found oil in the coolant and feel that either the head
gasket is gone or in addition the block needs replacement.
They might be right, but I have some questions:
1. If there is leakage between the cooling system and the oil why is
there no water in the oil. I don't know the relative pressures.
2. Why the oscillation in temp. This it seems to me might be caused by a
bad thermostat.
I need a second opinion.
Thanks for help in advance.
