Thanks everybody, For replying and giving your opinions. This way I can understand or at least have alternative opinions about what the problem "possibly could be" before going to another garage to have it checked. I'll take the advice and go and take a second opinion as most of you suggested before doing anything, and come back with more information. thanks - Deniz -------------------------------------------------------------------------- Message 2 in thread From: Dave Hinz ( Subject: Re: Seeking advice View this article only Newsgroups: Date: 2004-07-22 08:25:07 PST On 22 Jul 2004 08:11:32 -0700, Deniz <> wrote: > > I took the car to the Saab servcice.

If it's got that problem, suspect that it had been run without oil, which could indicate other (bigger) problems, but I'd talk to a different mechanic before jumping to any conclusions. > I took it to the guy who sold the car to me, to "try" returning the > car and obviously he said something like "he used the money and > cannot return it to me".

Can you isolate the noise more precisely, like with a mechanics stethescope? > So obviously I cannot return the car, other than going to court and > hope to get something like half of the money I paid. Not a viable option, IMHO. If I sell the car > to scrap yard I'll just get %25 of what I paid.

Well, if you wait until it breaks, it's going to break more than what might need replacement right now. Again it comes down to getting a good diagnosis - it may be a benign noise, or it may be a "You will soon grenade a rod through the block" noise. Can't tell from here. > What to do oh what to do? Find out what's really wrong, when you do, come back to us and we'll hash it out.

( Subject: Re: Seeking advice Get a second opinion on the noise. I would bet (especially considering the model year) that it is a timing or balance chain / sprockets problem rather than loose pistons or rod bearings. When the chain is slapping around inside the timing cover it can sound like something else to the unitiated. This is not an expensive problem (yet) but could be if you let it go till the chain snaps or skips teeth. -Fred W Post a follow-up to this message Message 5 in thread From: BL ( Subject: Re: Seeking advice View this article only Newsgroups: Date: 2004-07-22 14:05:57 PST It's not too difficult to find Saab engines around the Montreal/St. Bruno area. Depending on how much you have into the vehicle, and the condition of the car, it's often less expensive to swap the engine than to do a proper rebuild ( especially if the labour will be covered). Before you do anything, take Dave's advice and get a second opinion on the source of the noise ( look for an independant garage that specializes in Saab ), there is an excellent shop in Ottawa ( Scandinavian Auto Service ). Good luck BL 2004 Google
