Why They Won’t Pump Up
Sometimes, new hydraulic lifters face a problem.
They may not fill with oil, or “pump up”, as they should.
This can make your engine noisy or even damage it.
Common Problems
Let’s look at some reasons why this might happen.
- Dirt or Debris: Sometimes, small bits of dirt block the oil passages.
- Oil Pressure: If oil pressure is low, lifters can’t work right.
- Wrong Installation: Putting them in the wrong way can cause issues.
- Defective Lifters: Sometimes, new parts might not be made right.
How to Fix Them
Here are steps to help fix lifters that won’t pump up.
- Check for Dirt: Make sure oil passages are clean and clear.
- Verify Oil Pressure: Ensure your engine has enough oil pressure.
- Correct Installation: Make sure lifters are put in the right way.
- Replace if Defective: If a lifter is bad, you may need a new one.
Checking Oil Passages for Dirt
Clean oil helps your car run smoothly.
Use a cleaner to wash away any dirt in oil passages.
Ensuring Enough Oil Pressure
A gauge can tell you if your oil pressure is good.
Your car manual will say what pressure is best.
Installing Lifters Correctly
Each lifter must sit just right in its spot.
Check a repair manual or ask an expert for help.
When to Replace a Lifter
If a lifter is made wrong, it won’t work.
A mechanic can tell if you need a new one.
What Happens if You Don’t Fix It?
Your car might get louder.
Parts of the engine could wear out faster.
It’s smart to take care of lifter problems early.
