A push rod in an AMC 4.0L 243 CID engine can come out of place due to several possible causes:
1. Valve Train Wear or Failure: Worn rocker arms, lifters, or camshaft lobes can cause improper movement, allowing the push rod to slip out of position.
2. Improper Assembly: Incorrect installation of the push rod, rocker arm, or lifter can lead to misalignment and eventual dislodging.
3. Valve Seizure or Sticking: A sticking valve can prevent normal movement, causing excessive stress on the push rod and possibly forcing it out.
4. Over-revving the Engine: Running the engine at excessively high RPMs can cause valve float, where the valve cannot follow the cam profile properly, leading to push rod misalignment.
5. Bent Push Rod: A bent push rod, often caused by a stuck valve or hydraulic lifter failure, can fall out of place due to misalignment.
6. Collapsed or Faulty Hydraulic Lifter: A collapsed lifter can reduce tension on the push rod, allowing it to move out of position.
7. Low or Contaminated Oil: Inadequate lubrication can cause lifter or rocker arm failure, affecting push rod function.
Each of these issues can disrupt the precise alignment and operation of the valve train, leading to a push rod coming out of place.
