How to Check Pushrod Length with Engine in Car

Tools and Materials

• Pushrod checker
• Feeler gauge
• Wrench

Safety Precautions

• Disconnect the negative battery terminal before beginning.
• Allow the engine to cool down before working on it.
• Wear safety glasses and gloves.

Instructions

1. Locate the pushrods. They are typically located on the top of the engine, between the rocker arms and the lifters.
2. Insert the pushrod checker into the pushrod. The checker should be a snug fit.
3. Use the feeler gauge to measure the gap between the pushrod and the rocker arm. The gap should be within the manufacturer’s specifications.
4. If the gap is too large, the pushrod is too short. If the gap is too small, the pushrod is too long.
5. To adjust the pushrod length, use a wrench to loosen the locknut that secures the pushrod to the lifter. Then, turn the pushrod until the gap is within specifications.
6. Tighten the locknut to secure the pushrod in place.

Tips

• It is important to check the pushrod length when the engine is cold. As the engine warms up, the metal expands and the pushrod length can change.
• If you are not sure how to check the pushrod length, consult a qualified mechanic.

Conclusion

Checking the pushrod length is an important part of maintaining your engine. By following these instructions, you can ensure that your pushrods are the correct length and that your engine is running properly.
