Saturn vue V6 lifter noise when first started
Fixing or replacing damage parts. You can try heavier oil. 10w40
If it is a Tapping sound it is normally a lifter. Could also be a cam, pushrod, and or a rocker arm. Tapping is normally upper motor. If it is a knocking noise it is normally in the lower motor. If the noise gets louder when warm most likely a lifter is going bad. As the oil heats it thins slightly causing more oil to bypass inside the lifter which it is not supposed to do
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.
The thing that could cause a knocking noise in your car is the same thing that could cause it in all cars A rod that or a flat lifter. it all really depends on where the knock is if its higher and to the back of the motor, it could be a motor mount
Is it a lifter ticking?
could be a lifter sticking
ticking noise is usually "lifter noise". if this noise increases in speed when accelerating then it is "lifter noise". just change your oil.and or maitain proper oil level.try using a medium to thick oil 20/30 20/50 , there is a product call lucas which also helps your oil lubricate the engines moving parts easier. i have use it, and it works , it takes a few miles but it works.
Worn valve train parts due to high mileage, lack of maintenance, abuse or contaminated motor oil (coolant mixing with oil).
Yes it can, but try to isolate the sound by using some thicker weight oil and/or oil additive like lucas to quiet the ticking lifter. If the noise doesn't change it's probably an exhaust leak, if it quiets down you might have a collapsed lifter.
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?
