ENGINE COMPRESSION?

1996 Oldsmobile 98 • 6 cylinder FWD Automatic • 1,310,000 miles

What is the exact engine compression suppose to be in a 1996 oldsmobile 98 with a 3.8?

The lowest reading cylinder should not be less than 70% of the highest and no cylinder reading should be less than 689 kPa (100 psi). Perform compression test with engine at normal operating temperature, spark plugs removed and throttle wide open.
