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.
hydraulic lifter? Rocker arm?
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.
a lifter
Stuck hydraulic lifter.
A clicking noise in the engine of a 91 Ranger could indicate a problem with the valves. A valve lifter in the engine may be worn or stuck.
That is lifter noise, they probably need adjusting
Saturn vue V6 lifter noise when first started
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.
I have the same car with the same clicking noise right after you start the engine. The noise stops shortly after starting. There was a recall from Chrysler for this problem. Contact your local dealer regarding this matter.
Speaking from experience, first checking the timing cover housing. If the noise is coming from there, you either need to replace the timing set or replaces the oil pump (oil pump went out on mine, and I didn't realize it until it jumped timing.. aka "new engine time")
