SAW A WHITE MIST COMING FROM MY CAR AS I WAS ON THE HIGHWAY. WENT
STRAIGHT TO MY MECHANIC, MY MECHANIC OPEN THE CAP AND FOUND SOME OIL IN
THE COOLANT. HE SAID IT WAS NOT MUCH. SAID THE CAR WAS AT A STAGE WHERE
THESE THINGS HAPPEN. CAR DOES NOT OVERHEAT.
HE PUT IN A SEALANT...WORKS FINE....NO SMOKE OR MIST.
I'M KIND OF A PUREST AND DRIVING AROUND WITH ANY OIL IN MY
WATER/ANTIFREEZE MAKES ME WONDER.
IS THE ADDAGE "DON'T MESS WITH OLD CARS !" VALID? LET 'EM BE?

Sounds like a head gasket is failing judging from the white mist(steam) you
described that came from the car. The sealant will probably hold for a while
and delay the inevitable major repair.
Good Luck

Anyway, if your mechanic dismissed oil in the coolant as
inconsequential, he is wrong.

The head gasket is damaged...and will only get worse. Better get it
fixed before greater damage is done to the engine.

I think it is great that he is trying to save you money. However, I
agree with Gamini that it will be a bad failure when it goes. head
gasket failure can mean having to mill the head back to flatness if it
gets too hot and warps. Diesel heads sometimes don't take too kindly to
this. I can't remember exctly why, but I think it has to do with how
close the coolant passages are to the bottom of the head. I would
really suggest having the head gasket done before it does you in first.

Just my two cents.

Good luck,
Bill

As with all others, that is a sign of head gasket failure. You can do two
types of tests... one is CO detection... if you detect CO in coolant, you
got a head gasket problem. Another is more crude... pressurize the cooling
system... if pressure keeps going down without any external leak, then you
got a head gasket problem.

Thanks for the help.
So I end up with a head gasket problem with both tests!?

Well I realize it's best to fix things. But sometimes it depends on other
factors. Just to put some perspective on this. I had the same problem with
my daughters cavalier, put some gasket sealer in the coolant..... 2 years
ago with no further problem. It might give out tomorrow, or last another
2 years - who knwos

cheers, guenter

Yep, but both can tell you no also... If no CO and no pressure leak.... then
head gasket is OK.

Any coolant in the engine oil?

Also, consider that the transmission fluid is pumped through the bottom
radiator tank to be cooled and that loop could be leaking - transmission
fluid into the coolant.

So be sure of the oil source before tearing into anything.
