you can try adding "lucas engine oil additive: but pretty much all that is happing is the lifters are little noisy until the oil circulates thru engine and lifters, basically not much you can do about it
Worn valve train starting with the camshaft lobes.
if it is a steady tick it may be your lifters,if it goes away it could be that your truck needs a tune up,if not chances are your lifters are not operating and you should get it fixed or your problem will get worse.
Insufficient oil or problem with pump.
Lifters dont really knock, they chatter. You may have a bigger problem.
Rods and Rocker arms were the problem with my Malibu after changing lifters
Did you get an answer to this questiosn about the loud squeal in the mornings? I have the same problem, and thought it was just a loose belt - but no.
Does morning run affect any health or heart problem
I had the same problem with a 98 contour, It was the fuel pressure regulator.
I don't know about the Explorer but I had an experience with a Ford Mustang. I changed about everything I could think of related to the non-starting problem. Then I discovered there was a filter in the gas tank. Changed it and the problem disappeared!
i have that problem. i was told it was the lifters, but it's a pricey job. that's the best i can do for you. i believe you have to remove the head gasket in order to get to them. -NEW ANSWER- I HAVE THAT PROBLEM ALSO... MY MECHANIC TOLD ME THAT THAT SOUND IS THE LIFTERS, BUT WHAT IT ACTUALLY IS DOING IS THE LIFTERS ARE TAPPING AGAINST THE DIPSTICK IN THE CRANKSHAFT. HE TOLD ME NOT TO WORRY, IT IS AN ANNOYING SOUND BUT IT'S NOT DOING ANY INTERNAL DAMAGE TO THE MOTOR... IF YOU WOULD LIKE TO GET RID OF THAT SOUND, THEN YOU WOULD HAVE TO OPEN THE HEAD, AND HAVE THE LIFTERS REPLACED. The Crankshaft is nowhere near the lifers. It's the rockers slapping against the lifters that you hear. Not much of a problem if you don't mind the noise, just keep an eye on your oil pressure.
Yes, the lifters on a 2002 Ford Ranger with a 3.0-liter engine are adjustable. However, they are typically hydraulic lifters, which automatically adjust to maintain zero valve clearance. If there are issues with noise or performance, it may be indicative of a problem with the lifters or other components in the valvetrain that may require inspection or replacement.
Lack of oil lubrication to the valve lifters.
