Hydraulic Flat Tappet Lifter Failure

Several factors can lead to hydraulic flat tappet lifter failure:

1. Lack of Proper Lubrication

Hydraulic lifters require sufficient engine oil flow for proper operation. If the engine oil is not changed regularly or if the oil becomes contaminated, it can lead to lifter failure due to inadequate lubrication.

2. Worn or Dirty Oil

Old or dirty engine oil can contain contaminants that can damage the lifters over time. It’s essential to use the recommended oil type and change it at regular intervals.

3. Incorrect Installation

Incorrect installation, such as improper lifter preload or incorrect lifter orientation, can lead to premature wear and failure.

4. Engine Overheating

Overheating can cause the lifter components to expand excessively, leading to interference with other engine components and eventual failure.

5. Lifter Collapse

Over time, the internal components of the lifter can wear out, causing the lifter to collapse or fail to maintain proper lash adjustment.

6. Excessive Valve Spring Pressure

Excessive valve spring pressure can put undue stress on the lifters, leading to premature failure.

Hydraulic Flat Tappet Lifter Preload

Here’s a brief overview of the importance of preload and how to set it:

1. Starting Position

Ensure that the lifter is on the base circle of the camshaft lobe for the valve you are adjusting. This means the valve should be closed.

2. Initial Adjustment

Back off the adjusting nut or pushrod seat until there is clearance between the pushrod and the rocker arm (or camshaft if adjusting directly on the lifter).

3. Zero Lash

Slowly tighten the adjusting nut or pushrod seat until all the clearance is removed between the pushrod and the rocker arm (or lifter). 

4. Preload Setting

Typical preload values can range from 0.020 inches to 0.060 inches, but always consult the specific engine’s service manual or lifter manufacturer’s recommendations.

5. Tightening Sequence

If adjusting a rocker arm setup, be sure to follow the correct tightening sequence and torque specifications. 

6. Recheck

Recheck the preload on all the lifters to ensure they are within the specified range.
