The malfunctioning lifter will cause the pushrod to bend and fall out of space. When that happens,
it leads to a dead cylinder that might break valves, rocker arms, or even damage the entire engine
.
Is it OK to drive with a bad lifter?
What Happens If You Drive With A Bad Lifter? The inside of the lifters can go all the way down to the point where they contact the camshaft and damage it if you drive for too long on them. If your lifters are bad,

What happens if a lifter collapses?
Consequences. A collapsed lifter puts a great deal of stress on a vehicle’s valve train, and the weakest link is usually the pushrod.
Collapsed lifters can easily bend pushrods, which will subsequently fall out of the space between the rocker arm and the top of the lifter
.
Can a stuck lifter fix itself?
The lifter that is stuck should tick under the rocker arm. Loosen the rocker arm bolt and remove the lifter. Fill a small cup with penetrating oil and soak the lifter in it, preferably overnight. Reinstall the lifter and torque the rocker arm to the correct specification.
What causes a lifter to drop?
Valve lifters are one of the first components to suffer wear when the oil pressure is consistently low. Low oil pressure can result from a number of factors, including
excessive camshaft end play and worn cam bearings, worn oil pump gears, worn crankshaft journals and bearings and worn main and rod bearings
.
Will bad lifters cause misfire?
In the event of a faulty lifter, the cylinder will not be able to burn fuel and mix air. As a result,
cylinders misfire
, and you experience a slower acceleration.
How do I know if my lifters are bad?
To better hear the noises, place a stethoscope over the valve covers or plenum and move it from the front of the engine toward the back, listening every 6 inches or so.
Any obvious clicking or clacking noise will indicate a maladjusted lifter or a worn hydraulic lifter
.
Can you replace lifters without removing heads?
Can you replace lifters without removing heads?

Does seafoam stop lifter noise?
Seafoam CAN be used in the oil. However,
it’s not going to fix a lifter tick

What causes lifters to knock?
A lifter tick is caused when
the push rod or camshaft doesn’t make continuous contact with the lifters
. This can be because the lifter has become worn out, as is the case usually with hydraulic lifters, or the valve has come out of adjustment.
Why do lifters tick when cold?
In the mornings or when the engine is cold,
the oil has had the chance, due to gravity to drain out of these back down into the oil pan
. When you start the engine when it is cold, this can produce a ticking sound as you describe. This happens as the lifters are moving without oil initially.
