White smoke? Smells funny? Does it stop smoking when it warms up?
Hope it's a bad head gasket sucking coolant into the cylinders or might be a cracked head. One bad thing on 99s is the coolant tank. Too small and too low. If the owner is not diligent about keeping the tank topped up, air gets sucked into the head causing hot spots eventually causing a crack usually in an inlet port. The crack closes up when warm. If in the exhaust port you'll see bubbles in the coolant.
The compressions don't look that bad. Remember this engine only as 7.2:1 compression. So readings around 150 are normal.
