damnit. as i went to pull in the garage all of a sudden i look in my rear view and see smoke comin up all over from the exhaust, rev a lil, it still puffin.

back out, have mom start it, see it looks like bluish smoke. pop hood, smoke inside the engine compartment! wtf? same color as exhaust, exhaust leak? turn off car, open up oil and still full of oil, nothing lower than about 4 weeks ago.

gunna have my dad take a final look at it today, im goin up to michigan tonight in my jimmy i guess. maybe use the warranty i purchased when i got this car used

99 9-5 w/ 77k miles on it. have a 3 year unlim. mileage warranty that went in effect 14 days ago. so yea. hopefully that will cover it, figure out if my exhaust leaks also, if it does, time for new exhaust ;)

what should i check personally b4 taking it in to a dealer/ saab specialist?

Usually bluish smoke on start up indicates blown turbo seals :cry: Its a fairly common problem with the 9-5 and will require a new turbo. Its down to the poor pcv system of the car. You will find no end of threads and information on this subject in the 9-5 forum. Its unlikely that your exhaust is broken (well if it is it wont contribute to smoke). Hopefully your warranty will cover it. Checks to be made would be replace all pcv pipes, drop the sump, clean strainer, replace turbo. Replace oil with fully synthetic and maintain 6000 mile oil changes.. :confused:

i had the same problem and i took it to the dealership thinking it was the pcv or turbo. it turned out that they said that it was due to an internal oil leak, moist likely the valve seals. they checke the exhaust and found no signs of oil residue from turbo failure, and checked the pcv, both were fine. i am not sure if they checked for sludging tho. mine started smoking only at startup, but now whenever i come to a redlight i have a huge cloud of smoke behind me.:cry: i really dont know what to do, or if the dealership was even right about their diagnosis.

The valve seals would have to be pretty shot to do this at the lights, plus i have never met a 9-5 driver who has had theirs replaced, I think its the PCV and/or turbo :confused:

could it be sludging? i know this is one of the most common things that pop to mind when someones car has a problem. i think i might change to high milage oil and maybe some lucas oil stabilizer. would using a thicker oil help any?

Sludging is caused by the pcv system. Only use fully synthetic oil such as Mobil 1.
As I recal
white smoke = coolant,
blueish smoke = oil (could be turbo or valve seals, but very rare in the 9-5 to be valve seals)
Black smoke = fuel

I would think the last thing you need to use is a thicker oil. Saab now specify fully synthetic because it runs thinner than standard oil yet doesn't break down as easy. If you put thicker oil in and have constricted oil passages its gonna kill your engine for sure.

i really didnt think that it was the valve seals. i am very cautious about the saab dealership near me, since they have only had saabs for three weeks:eek: we no saab certified machanics:eek:. we in went in i knew more than they did. i am really not sure if i will returning to them. i asked the parts manager what kind of coolant to use and he said that he had no idea.

is there a way that i can check my turbo for failure? as of right now it smokes after a nice hard WOT at redlights.

well the oil is only about 2K miles old max, more like 1K, mobil 1.

im taking it to a specialist tonight dropping it off and leaving it there for them to look at tomorrow

hopefully its nothing THAT major. but hmm how much does it cost to get those replaced and changed etc.

i also will be having the ticking in my car looked at as well, although im pretty sure thats just a tappit out of whack.

my dealer quoted me about 800 dollars for the valve seals, and about the same for a new turbo. i now believe my problems to be the pcv hosing. the big one coming from the valve cover has a nice cut in it big enough to open. i also have oil inside the nipple. anyone know where i can find these hoses besides the dealership? saabsite? genuinesaab?

well about three days ago i noticed a cut in the hose coming from the valve cover going to the oil collector. the smoking had stopped and i was confused. i ordered a new pcv and nipple and hose and installed them this afternoon thinking all was well. i drove it and it seemed fine. later in the night i got on it really hard and when i stopped, a huge cloud of white smoke came from my exhaust and even filled the cabin. then after that, wheneve i sat idle and revved the engine, it would smoke. what else should i have changed? maybe the oil collector? and is there a way that i can just get a pcv filter and rig it up and not have the hose going to the oil collector? i am so confused:cry:

White smoke suggests head gasket failure :eek:

Is their oil in the water or water in the oil?

Any coolant loss?

there is no coolant in the oil or vice versus. i am really stumped, because it was blue today. i guess it was night time and i couldnt see the color very well. ithink i am going to pull the hose for the intercooler off the turbo and check for any signs of oil. also the pcv hose was completely burnt on the inside with a substantial amount of oil... about 1.5mm of build up. but i did fill the coolant last week when the fill coolant message came on. i gotta get this fixed soon, this is getting imbarrassing. anyone know of any good indy saab mechanics in nc?
