OP says he has 0 PSI in cylinder #4, 120+ in cylinders 1-3.

I think they already narrowed it down to no compression, which leaves either a broken valve, bad rings, or a destroyed piston. Nothing to do with coil packs. This generation did not have individual coil packs, only a DIC which is basically one coil pack that covers all four cylinders.

OSVSCT maybe a burnt valve by the sounds of it. I had it happen in my 99 9-3 with the B204

amath80 A blown head gasket causes oil, exhaust gas, or cooling water to get into the wrong place. Usually water in the oil is the most common. The oil will look like chocolate milk. Some engines leak cylinder pressure into the cooling system. This pressure boils away and/or blows out the water thru the overflow tank. Your temperature gauge will fluctuate up and down, from what little water that's left circulating past the temperature sensor. Also, if you lower your rpm, the pressure decreases and allows the water to circulate correctly.

Erk 3 psi isn't much. Sounds like a valve. Sludge wouldn't kill a valve. I'm in the albany area as well. Perhaps I could help you with it

paperstreet Well I checked it. I put a little oil in the cylinder and got no compression. So I decided to put just a little more in and got 3 PSI. I guess this a little good news all things considered.

I dropped it off at the shop after that. I hope to get a full diagnosis from this guys to confirm. If they quote me an astronomical number then I will take it back and try and do it my self on the evenings and weekends.

I will post the results from the shop and keep posting progress here. Maybe someone can gleam some information from this ordeal.

Im still wondering if this is engine sludge related.

kingofkrunk my ng900 was doing the similar stuff ... i dunno about the codes though ... i changed heads ... and when i had my other head on the bench i checked to see if it would hold compression(mine was in cylinder 1) by putting water on it to see if it was sealing properly .. it wasnt ... bad valve seat

you should be able to figure out whats going on onbce you get the head off

PoisonBeef I know your pain, my car was doing great until it misplaced a few gears in the transmission last week.

Good luck.

paperstreet I am going to crack it open this afternoon and look at the valves. In the end I may have to end up taking it to a shop. I really wish I had the time to really roll up my sleeves and dig into it. But the more I look into it the more I realize that this could take a month or more of wrenching it in my garage. Best I can do at this point is diagnose it and hope the repair price is kind.
This will probably end up costing me a few grand. It will definitely hurt. Im so disappointed. I have been into saabs and owned one or more for over 15 years now and no real major problems have ever surfaced engine wise. This was the last thing I expected. Quirks and minor stuff aside the saab has always been reliable. What a week! : saab goes out of business and then my engine flakes out. GM can suck it.

WyldSaabMan Have You tried squirting some oil into the cylinder and then doing the compression test?

If compression goes up, that points to your rings. However at 0psi I'm not sure that would really help

The thing to do at this point would be a leak down test so that you can try to identify where your leak is. If you can't find a leak down tester you can always just hook compressed air up.

To do this make sure cyl 4 is at TDC and lock the engine there with a breaker bar on the crank bolt.

PoisonBeef People have rebuilt plenty of these motors.

Are you willing to dig into this thing? Pull the head and take a look, It could just have a cracked valve and thats not as bad...
12-27-2009 08:16 PM
LostAbbott I am looking for similar information except for a b235r...

Rebuild or new/used motor?

Has anyone rebuilt a '02 2.0 Turbo? Is it worth it? Im a little leery of a used motor because you never know if its been abused. Any advice? What Mods are best while rebuilding?
12-27-2009 09:26 AM
paperstreet Thought it might not have had one must be the new 93's ...Could this be the cause of an engine failure on this level?
OR...Could this be the result of oil sludge?
12-27-2009 09:07 AM
PoisonBeef OG 9-3s have a CPS.

Although 0 compression in #4 is definitely a large problem.
No I don't know if the crank position sensor has been replaced. I thought the old 9-3's dont have one?
