Well, i'm gonna step in it and take the heat, again.
If you have a blown head gasket, there's NO fix other than to replace
them both, as Tom points out. And the heads MUST be tested for warp and
But you CAN measure the coolant found when you drain the oil as it will
separate. If there's no coolant in oil, then you are pretty safe.
If there IS coolant of any volume over a few tablespoons then you might
have had 'bearing wash' which is the wearing away of the finish surface
of the bearing.
But it's still not all lost.
The engine failure Tom refers to is when the bearings SEIZE after the
smooth surface is eroded way. That is due to high ridges in the bearings
overheating due to load stresses, this causes the oil next to them to
overheat and 'coke'. Like cooking oil does in an overheated frying pan
Once that 'coking' builds to a certain point it breaks free, sliding
around until it jams the bearing, which then spins and seizes.
So what's the fix?
Use Mobil 1 or a FULL synthetic that has a significantly higher coking
While it cant be guaranteed there wont be subsequent failure, there
certainly wont be the same degree of coking buildup as with a standard
Take it or leave it, that's my hypothesis, and I'm sticking to it...
because I put over 70,000 miles on a 3.8 that had blown HG and had washed
bearings. And becuase it makes sense!
Dont skimp on a cheaper synth! and your mileage may vary, but I'd go for
it, if I were you.
And after the first oil change you can extend the change mileage some,
unless you only use the car on short trips.
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
