lifter

Some ticking noises can be normal. The fuel injectors do make a ticking noise as part of their normal operation and depending on the vehicle can be heard louder than usual. I would ask for help from one of the...

Hi there. When you have the cylinder head rebuilt and a valve job done then that will change the height of the valves in the head. The lifters are set a specific thickness to offset the depth that the valves...

Hi there - no, a tapping valve lifter (https://www.yourmechanic.com/article/how-to-inspect-valve-clearance-adjustment-by-robert-kulp) won't cause direct damage per se, but will run less efficiently (on that cylinder) while clearance is excessive and tapping occurs. Since the lifters are adjustable, you would certainly want to...

Add 1 quart of ATF to the engine oil and run the engine for 15 minutes at 2,000 rpm’s. This will thin out the engine oil and clean out the lifter with the high detergents. Then drain the oil and...

The lifter is not too much of a problem, but it could be costly to replace if you are having a technician replace it. You can try changing the engine oil and filter and running a oil treatment in the...

Hello - your "noisy lifters" (https://www.yourmechanic.com/question/noisy-lifters) could have a couple of causes: worn out lifters (they're hydraulic by the way, not adjustable), or poor oil supply to them. Poor oil supply could be a blocked oil passage, worn out oil...

The noise sounds like a lifter tapping on the engine. This is caused by dirty engine oil and or a plugged oil filter. I recommend servicing the engine oil and filter (https://www.yourmechanic.com/services/change-oil-and-filter) first. If the noise continues, then I recommend...

The tapping noise that you are hearing is the lifters on the engine not filling up with the engine oil either due to lack of oil pressure or they are stuck. First check the oil level and make sure that...

Hi there. Before removing the cylinder head the rocker arms and the push rods need to be removed. When removing the rocker arms, they will need to be loose and not tight. You do not need TDC, but close to...

Hi there. If the lifters are indeed tapping, then they are probably sticking. Try putting one quart of transmission fluid in the engine and run the engine for 15 minutes at 3,000 rpm. This will thin out the original oil...

If you pulled out one or more of your push rods you may have had a lifter pulled out of its hole and it would of fell onto the top of the engine block under the intake manifold. You will...

Hi there. The noise could be from the lifters not filling up with engine oil until the engine is warm or the pistons have too much clearance causing a condition called "piston slap". Check to see what brand of engine...

The lifter is tapping as either the oil pressure to the lifter has dropped or the lifter is sticking from old sludge build up from the mileage. Try changing the engine oil and filter and see if the lifter noise...

The noise that you are hearing from the engine could be one or more lifters ticking. The lifters use oil from the engine to create a hydraulic pressure in them to keep them in contact with the valvetrain. If the...

Hi there. Depending on the sound of the knocking noise and where the noise is coming from on the engine will determine if the engine needs replaced or not. If the noise is near the top of the engine, then...

Hi there. The noise (https://www.yourmechanic.com/services/noise-from-engine-or-exhaust-inspection) you are hearing is the lifters in the engine are not pressurizing up or stuck in the down position. Check the oil level on the engine and see if the level is low. If the...

Hi there. The lifters are sticking causing the push rods to be loose and tap on the rocker arms. Put one quart of ATF in the engine oil and run the engine for 15 minutes at 3,000 rpm's. Then change...

Hi there. First you will need to drain all of the engine coolant from the engine. Then you will need to remove the intake, exhaust manifold to the side that has the lifter that is tapping, and make sure that...

Hi there. The sound could be the lifters sticking and not getting oil to them. This would be for the noise lessens as the rpm's goes up. Add 1 quart of ATF Type F to your engine oil and run...
