A loaded question, but here goes since I’m looking for another 9-3.

This intake valve problem, on the 08’s, is it a matter of time before this shows up or are their some that will not see this problem?

If it is a chance of happening, any numbers on what percent is affected?
No one knows.

The way I understood it from explanations here and other places is that it is pretty much a matter of time. It usually happens in the first 100k miles, but may also happen after. The older the car without the new valves, the bigger risk it is and the more likely it is to happen sooner than later. And I understood it as it's all of them. Or at least enough of them to where you should count on it happening and being prepared. GM hasn't given out enough info to track down the batches of valves and what cars they went into. Not sure if they would, anyways.

This will effect all B207 2.0T engines for the 2008 model year. There is no escape. Authorized Saab repair wants $2600 to fix mine but I don't drive the car much and it usually starts up especially when above freezing temps. Mine has 91k miles, original owner. Only a matter of time. If you find a 2008 9-3 2.0t and the intake valves haven't been changed then deduct $2-3k from the asking price.

Mostly correct. My car is a MY2007, built on 09/2006 and I had the intake valve issue, so far I think I'm the earliest recorded, but all MY2007-2011 cars should be wary.

I'd say a $2000 deduction for a car with no known record of a valve swap is fair. I bought 8 new valves (the improved BioPower versions) online for less than $200, and had the head redone/reassembled for less than $1200. The car has been flawless for the past 3 years since. It wouldn't even start when it was 0 degrees F a few years ago at 90K, and ran rough at 15-20 degrees F, I'm now at 150K and it's perfect even on the days that are -10 or -15F (She's a little cranky at -20F, but so am I).

For the record, I had two cylinders with low compression, two were in the 90's and two were in the 180's, so it can be random valves. If you buy a 2.0 after 9/2006 the chances are you will have at least one valve that has erosion unless it's a BioPower engine (which I think came out in MY2010 and mostly on 9-5's) or the motor has been swapped to the BioPower valves.

Wow, you're the first I've seen to have a car made before mine and had the issue. I think I'll try to do a compression test just to check, even though I have no signs at 120k miles. Borrowing the tool is free, and it's quick peace of mind.

I've got a 08 2.0T that needs the valves replaced. Also, the timing chain is blown, probably related, as I could only start the vehicle in the summer and thus used in the warmer weather. On a positive note, the car has no rust considering it is a Canadian vehicle. To repair it, the best quote I've gotten is $1800 CDN for the valve job and $600 CDN for the timing chain at Beacon Motor in Toronto, which is/was a speciality Saab shop. I've yet to take it there, probably have to bite the bullet soon and take it in. These cars were well designed and a joy to drive, except for these engine issues.

You might want to contact Zoom Auto in Scarborough and see what they quote.

2007 Saab 9-3 2.0T
Build Month/Year: 12/06
Mileage (in Miles): 122,278
Have you experienced this issue (Yes/no)? Yes
If yes, have you validated w/ compression test (yes/no)? Yes
If yes, did you have your car repaired (yes/no)? Not yet
(Optional) If yes, what was your out of pocket cost? n/a

I tested the compression today. It was a cold compression test. Outside temp. 42 degrees F. Cylinders 1,2, and 4 were between 215 and 230 psi. Cylinder 3 was 90 psi.

I plan to do the work to replace the intake valves myself. I have the WIS for step-by-step on how to remove and install the cylinder head. The part that I'm trying to figure out is what to do with the valves / head when I get the cylinder head out (i.e do I have to take it to a machine shop or can I do everything I need to do myself?)

Have an expert fix it.you are in Virginia. The only guy I know in the USA who is good with these heads is on Facebook Josh Billheimer, category v I think he calls himself. Ohio. But it is hard to Believe there are not machine shops in Virginia capable of going a three angle valve job on your seats. And true the head if needed. New springs , retainers, seals and new valves. OEM valves are expensive around 700 usd for 16. You can buy aftermarket valves for 8 dollars each but they are not sodium filled stems. Good luck.

2009 2.0T with 165,XXX KMs, first indication that I may be having intake valve issues. Caveat being the car has not been used for 8 or 9 days, really difficult time getting it started and running without stalling, about 8'C so not too cold either.

Valve problems on 2008 9.3 2.0T petrol Aero wagon

I started to get the cold start misfiring problems a few months back, got worse with the colder weather. Mileage 85,000. Was advised to change plugs, but made no difference. Found a Saab specialist who did a compression check and confirmed valve problem. The intake valves were replaced, and the problem has gone away. Also the engine just feels in much finer state and fettle than it did before. Cost was £1300. Considering the age and value of the car this is quite a cost, but am now hoping to get many more miles out of the car. besides which it is a great car, and I do not know what I would replace it with
Going through his exact problem right now - hasn't been officially diagnosed but doing compression test on Friday. How has your motor been since?

pretty sure this was a false alarm after sitting for so long. Has not demonstrated again, at all
