How long does a turbo engine last, in terms of milage?

I am considering buying a 2000 Saab 9-3 hatchback with 68K km's. It
has a 2.0 Litre Turbo engine.

Also the lug nuts on the wheels are rusted. A friend of mine told me
that this because the car might have been sitting in the snow and the
rust peeled the chrome off.

The guy who is selling said it had to do with "percussion" tools when
changing the tires.

What chrome? The ones I've seen are grey, either paint or galvanized.

Seems reasonable. I wouldn't worry about it.

No problem these days. Only carelessness and lack of maintenance
will shorten engine life. With a turbo, the engine is less stressed
as it need fewer rpm.

It is not uncommon for the Saab 2 litre turbo engine to last for 200,000
miles (320,000km) without any major work at all. I had a T16S of 1990
vintage that had done 215,000 miles when I sold it, all without ever had an
engine rebuild, and with the original turbo. As far as I know, it's still
going strong. Oh, and it still produced 190 bhp on a rolling road test.
Secret of long life - frequent oil changes, and synthetic oil.

In my experience Saab turbos are very reliable. It may depend on how
they are driven and how often the oil is changed. One should always
let the engine idle for at least 10 seconds before shuting it down.
We have had five turbo Saabs in our family and never had any problems
with the turbos or engines. The 1985 900T had 282.000 miles on it
when my son sold it to a Saab aficionado. Neither the engine or the
turbo had ever been touched and it still did not need oil between
changes. On the other hand,every suspension bushing, clutch, shocks,
and wheel bearings were replaced at one time or another. My son's
1994 9000 CSE has 225,000 miles on it and the turbo is fine. My 1998
9000 CSE has turned over 104,000 miles and aside from replacing the
direct ignition cassette the engine has not been touched.

Regarding the rusted lug nuts, Saab lug nuts are notorious for rust.
I did learn the other day from our lacal Saab tech that there is a
recall on 9-5s and maybe 9-3s regarding rusting of lug nuts on certain
types of wheels. If the wheels meet the criteria theyh will replace
them for free.

Good luck, R. Frist

If you can't get them free, SAAB sell them really cheap anyway.
Something like UKP 0.20 each IIRC.

While following this advice will not hurt anything, it really is based on
old procedures from before the turbos were water cooled. Nowadays, it is OK
to shutdown a modern SAAB turbo engine once you have parked the car. Reving
any engine just before shutdown is a bad idea.

I know the Classic engines are good for 300,000 miles. The NG engine
designs changed, so the book is out until there is a history on how long
these engine will last. I know my Classic 900 engine is much smoother
than my NG 900. The technician gave me a list of things to watch out
for on the NG engine. Then he told me I did not have to worry about the
Classic engine because it was a solid design - no nylon gears on the
timing chain(4 cylinder), no DI cassettes or rubber timing belts(6
cylinder).

With that said, I drive the NG Saab where it will get beat up. I had an
SUV back into the front grill at a soccer game and not leave a note :-(
So much for honorable "soccer moms or dads".

It's still not a bad idea to let it idle for a few seconds after a hard run,
the old oil cooled turbos would glow red hot for several minutes of idling,
the water cooled ones will still glow, but they do cool down a lot quicker.
When you shut it off, the water stops flowing too, if it's very hot the
shaft can still coke up oil.
