How can I tell if my Saab engine is leaking?
To properly diagnose this condition perform a cold (after an overnight stay is best) compression and leak down test. As an example, an engine with a 150-175 psi hot cranking compression reading may only show 75 to 90 psi when cold.
What happens if you have low compression in your engine?
If you have car engine compression problems, your car will either misfire when you start the engine, perform poorly or, if you have low or no compression in all cylinders, won’t start at all. You can’t drive your car for long, if at all, with low compression.
What’s the sound of a car with no compression?
This is the sound of car engine with no compression. The car just suddenly lost power and wont start. Not even crank. This is the sound of car engine with no compression.

What should the compression rate be in a car?
Insert the compression gauge extension and screw it in. Have someone crank the engine and watch the gauge until you reach maximum compression. A healthy engine should have 100 PSI per cylinder.
What kind of engine does a Saab 9-3 have?
Tedjs recently took us on a brief tour of the fuel injection system on the 2.8 V6 that powers the Saab 9-3 Aero. This time, he’s giving us a closer, more in depth look as he slowly takes a bit more of this engine apart.

What causes engine compression loss in cold weather?
Due to the nature of this issue it can be more prominent in cold climates and could exhibit the condition at a lower mileage; inversely in warmer climates it may be at a higher mileage. TAC has found that intake valve wear of the valve seat face will cause significant compression loss in cold temperatures that will not be readily apparent when hot.
