These engines would tick if they were low on oil. Try changing the oil and filter and rechecking it. But these engines were also good for having lifters go bad. If the oil change doesn't work, and providing the engine is in good mechanical condition (no sludge build up, etc...) put some lifters in and you should be good to go.
Bearing noise is usually deeper and comes from farther down in the engine. Lifter noise is more of a ticking and is up in the engine heads.
NO. The engine computer is in open loop until the engine heats up to operating temperature 195 degrees are more. that means it don't hear the lifter noise and by the time the computer can, the lifter quites making noise.

To stop engine lifter noise, first ensure that the engine oil is at the correct level and is of good quality, as low or dirty oil can cause lifter issues. If the noise persists, consider using an oil additive designed to clean and reduce lifter noise. If the problem continues, it may indicate worn lifters or other internal engine issues, necessitating a professional inspection and possible replacement of the lifters. Regular maintenance and oil changes can help prevent such problems in the future.
Usually it's the lifters in the engine making that noise until they become fully pressurized with oil, then they stop ticking, like on the 3 liter caravans.

The most common cold engine noise in a Chevrolet 4.3L is lifter clatter. Try using a lighter weight oil and see if the noise changes or goes away.
Engine lifter noise can often be reduced or eliminated by using high-quality motor oil that meets the manufacturer’s specifications, as it helps ensure proper lubrication. Regular maintenance, such as oil changes and using oil additives designed for lifter noise, can also be beneficial. If the noise persists, it may indicate a more serious issue, such as worn lifters or insufficient oil pressure, which would require further inspection and potential repair.
