Can you drive with a bad lifter?
When you drive for too long on a bad or collapsed lifters, the inside section of the lifters can go all the way down to the point where they contact the camshaft and damage the camshaft. You shouldn't drive your vehicle for more than 100 miles if you have bad lifters. via
Can you fix a bad lifter?

Can a lifter tick fix itself?
As we've seen, sometimes there's nothing you can do but replace the lifter itself. This is one of the most expensive and time consuming options for those with ticking engines. However, it's important that you work to replace this lifter as soon as possible. via
How hard is it to replace a lifter?
Lifter replacement isn't particularly difficult from a technical perspective -- but it does require unbolting large chunks of your engine and reaching elbow-deep into its belly. via
Will a bad lifter hurt your engine?
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. via
Will thicker oil stop lifter noise?
Heavier oil will not quiet hydraulic lifter noise. The noise will usually go away as the motor and oil heat up. If the tapping continues after the vehicle is warm, you may have one, or more, faulty lifters. As any oil gets dirtier, the chance of lifter noise increases; heavier oil just makes the problem worse. via
Can you replace lifters without removing heads?
Can you replace lifters without removing heads? Yes, it is possible to change the tappets without removing the heads, and this is what we are going to demonstrate. via
Can you replace lifters without replacing Cam?
The camshaft does not necessarily need to be replaced when replacing lifters, and often times is not. In the case of a 4 cylinder, especially, I would replace lifters without doing the camshaft since you can replace the lifters without removing the head. via
What causes a lifter to go bad?
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. via

How do you tell if a lifter is collapsed?
The most obvious symptom of a faulty hydraulic lifter is the noise it creates in your car's engine. You can usually distinguish the faulty lifter by the distinct sound. Instead of a knock or ping, a faulty hydraulic lifter will usually make a sound more reminiscent of a tapping sound. via
Can you replace one lifter?
No you do not have to replace all of the hydraulic valve lifters but I recommend that you do. You have to open up the engine just to get the single one out so might as well replace all of them while you're at it. via
