Smoke out of exhaust and loss of power

1994 Saab 9000
2.3 t

First before I noticed the smoke, there was a high pitched whining noise coming from under the hood. The next day when I started it, smoke came from the exhaust tail pipe and more would come out when I accelerate. Under the hood, where it was once welded before due to a crack, some smoke comes out. That is located next to the bolts and connector piece between the downpipe and the turbo. What could be wrong with my car? The turbo went bad?

This sounds like antifreeze entering the crankcase..blown head gasket .warped head . cracked the block . pray it's only a blown head gasket and get it checked for cracks and straightness with a new head gasket might be all that's needed. the high pitched whining noise was probly your waterpump spinning dry . might need a new water pump to (where is your coolant lvl and what is the strength of it for the cold weather)
and a few exaust doughnuts wearing thin letting smoke out in the engine compartment not healthy to breath you should get it looked at.

Sounds like your turbo let loose. The smoke is the coolant that runs thru the intercooler which cools the turbo. I would say either remove the turbo from the system , or replace it.
which engine is in your car?
w/o B234R eng; (T25 turbo) [rare]
or
w/B234R eng (TD04 turbo) Garrett type? (tag72623 Garrett pt# 452083-15)

for a used Turbo you are looking at around $150 plus shipping. but you will need to know which turbo you have of course.

The intercooler is gonna run an additional $50 or so (Hollander part number 317-51291) plus shipping.

give me a zip and tell me which engine (or turbo) you have and I will be happy to get you hooked up with the salvage yard closest to you that has these parts.

The noise is possibly a belt slipping and the smoke if out of the exhaust is engine strain, if from under the bonnet probably rubber from the slipping belt.

Power (acceleration) loss at mid-high RPM only


Loss of acceleration, the backpressure noise and such are kinda tell tale signs of that converter having problems, feel the exhaust out of the tailpipe it will be warm normally have someone step on the gas and if its super hot it'd be a step in the right direction.

I have a 1994 chevy s-10 blazer vin w with a 4.3 l vortech its white smoking with loss of power and is missing very bad


white smoke is caused by coolant mixing into your combustion camber which is burning through your exhaust. More than likely a leaking head gasket is at fault

High pitch tone from my 2001 chevrolet S-10 pickup


You didnt indicate whether you ran the engine with the belt removed while replacing the alternator,if not do so and verify noise. Sounds like you may have a vacuum leak, best way to diagnose would be with a smoke machine if not available with the engine cold try spraying carb cleaner around the intake & any suspect vacuum hoses with engine idling look for a change in idle speed or elimination of noise. Hope this helps you out

Saab 9-5 blowing white smoke from exhaust


One way to check for a blown head gasket, is to simply smell the coolant reservoir. Pop the cap, and see if it smells like raw gas. Every headgasket, I've diagnosed has had this smell, even if the oil is not contaminated. Another way is to hook up a coolant pressure tester, and run the vehicle for 15-20 mins or so. If the head gasket is blown, the pressure will exceed 15 psi. sometimes as high as 25 psi. If there is oil in the coolant overflow tank, the head is cracked, about 90% of the time.
I'm working on a 03 Saab 95 2.3l t. This vehicle smokes on initial start up, then the smoke disapates, and the vehicle is fine. Another mechanic diagnosed it as bad valve seals. I disconnected the pcv system, and the vehicle no longer smokes. If the valve seals have gone bad, the vehicle will smoke on acceleration. Also if the turbo seals are leaking it will smoke more heavily on acceleration.
