Why would be oil be blowing out the dip stick in a Saab turbo 900?

I had this happen years ago with a Suzuki Samuari ... smog hoses would blow off engine, oil would blow out every conceivable connection. Turned out it was a clogged catalytic converter, causing excessive back pressure, blowing past piston rings, and pressurizing the crankcase. Since your car is turbo charged, it >might< be a frozen turbo that's creating backpressure, or a defective catalytic converter. Unfortunatly with my Samurai I took it to a shop for diagnosis, and they said the engine was shot. I bought a rebuilt engine and installed it, only to find out that the same condition occurred, and finally traced it to the catalytic converter. A quick test is to take a mallet and bang on the catalytic converter. You should NOT hear anything rattling around inside! If you do, it could be the 'core' inside the catalytic converter has broken loose, and is pushing up against the out-pipe and causing the backpressure. Hope this helps...but I'd be worried about the turbocharger...


When does a car need a catalytic converter?

You should get one from the start when you bought your car. A: With all due respect to the answer above, cars were produced for 73 years before the introduction of a Catalytic Converter (1975) 35 years ago. Any car made before 1975 is not required, nor designed, to have one (CAT's produce a LOT of heat that older cars are not designed to deal with). Cars made between 1975 and 1995 are only required to have one, if its emissions cannot be controlled under other conditions (OBD I systems). With the introduction of OBC II systems in 1996 the system required the use of the Catalytic converter to function without errors.

If a 2001 Volkswagen Jetta's catalytic converter rattles and falls apart inside itself would that be covered under the voluntary VW factory extened emissions warranty even if you bought the car used?

AnswerYes, even used. See the EPA link below and show it to the VW dealer. Voluntary warranty extension from 8 years/80,000 (req. by EPA) to 10 years/120K miles. But, if the catalytic converter has ANY visible damage the factory will refuse to honor the warranty. Since it can't be determined if the converter or the damage is the root problem. So before you spend the money to get the technician to determine if it is covered check the converter yourself.


How much is a used catalytic converter worth?

That depends on size and how the structure is made, they can range from $20-$200.tHIS 2002 MERCURY COUGAR..I BOUGHT A SET OF THREE..ONLY NEEDED 2 SO I HAVE 2 USED AND 1 NEW HOW MUCH YOU THINK


You bought a used car 2 weeks ago and you got a 3 month warranty on engine and gearbox and now the catalytic converter is gone do you have any comeback with the garage?

Yes!!!, The catalytic converter (CC) should not have anything wrong with it if the engine was tuned correctly. If the engine was running rich, because the computer was compensating for a sensor that is giving incorrect readings then the CC would clog with the carbon produced by running too rich. This is the most common cause of CC failure.
