Did you ever get a diagnosis on this? Did it prove to be the hub assembly like guehouse suggested? If so which wheel? I have the same symptom of a sound from the front end like an airplane prop slowing down when decelerating. 2003 Montana AWD w 80K miles.

Not yet but based on guehouse diagnosis and the shop manual, probably is the wheel bearing. Think it is the passenger side.

I had the same problem and it turned out to be a blown head gasket.
 
Replaced the head gaskets and remanufactured heads and have gotten another 25000 miles of it and still going strong (172K to date). Rear side of the engine is a bear to work on though but I was able to complete the job (first engine top end rebuild). The shop manual is almost required if you are going to do it yourself.
 
Good luck

Well, I just spent all day changing the front left wheel hub-bearing assembly, and yep, that's what the airplane prop noise was. The worn assembly was so bad that, after removal, it could not be turned by hand, and the ABS sensor housing (integrated with it) was all cooked and distorted.

Just spent most of the day replacing the front passenger hub assembly and I am happy to say I could let the stewardesses go. The hub came apart and had rusty water in it. Gueman, thanks for advice, that solved the problem.

Gas odor from under the hood by gvanzant1

Last week, while on a trip, my wife and I noticed a strong gas odor coming from our 2005 Pontiac Montana. The odor is inconsistent: sometimes we notice it when the van is running; other times there is no odor at all when running. Then, we may notice it when the van is parked (not running), but again at other times, there is no odor while parked. So I took it to a mechanic who had it for several hours and couldn't find any leak nor noticed any odor. He started and restarted the van and even drove it a couple times. Nothing. There was no odor for 2-3 days, but then today, it was back and stronger than ever. If we notice it while driving, we simply pull over, turn the van off and then back on, and it usually disappears. What do we tell the mechanic to look for?

Radiator Repair 1997 Trans Sport by nthompson1
Jul 15, 2009 (5:24 am)

For now, a mechanic came to my house, changed oil, filters, thermostat, etc..
The obvious overheating culprit is a hole in the plastic end of the upper right side of radiator(gets air filter wet).
Radiator and labor costs about $450.
IS THERE ANY AVAILABLE SUBSTANCE THAT I CAN ADHERE TO THE OUTSIDE OF THE RADIATOR AT THE LEAK? ITS WORTH A TRY.
After spending $1450 for vehicle, $450 for title, plate, and insurance, and $100 for mechanic, I am trying any possible, cheap solution first.
If I have to have the radiator changed, should I have a universal coolant and reinforced metal gaskets put in, or keep as is(Dex Cool)?
Lets hope the intake manifold gasket and head gasket are okay.
Thanks a lot.
