How To Change 5.3l Lifters Without Removing Heads and CamShaft

Lifters are important because of their function in an internal combustion engine.

How To Change 5.3l Lifters Without Removing Heads

As a result of normal use and wear, lifters can degrade over time. To change 5.3L lifters without removing heads, follow the steps outlined below:

  • Start by having the engine analyses, and have the technical knowledge of removing a large portion of the engine, use the owner’s manual to get yourself familiarized with all the sensors, pipes, and ducts.
  • Remove the wires, sensors, and duct tapes, using the throttle box, disconnect the ducting and tubing as well
  • Peel off the upper manifold and also the lower manifolds, the manifolds are responsible for the distribution of air to all cylinders of the engine, disconnect all wires and sensors attached to the manifolds, there are a total of six bolts securing the upper manifold, take your time to have them a removed as well
  • Remove all bolts from the car engine as well as from the lower intake, and remove all fasteners even cloaked ones from the engine bay.

  • By following the correct pattern fit the new lifters into their sockets. For the new lifters to not wear out quickly, carefully do the installation and ensure not to mash the whole process together. Using gloved hands, rotate the lifters, using a wench, keep them accurate while compressing them with oil.
  • Proceed by installing back all the wires, duct tapes, and sensors you initially removed, after doing that in the right order, double-check to know everything in the engine is in the right proper place.
  • Allow some time to turn on the engine then wait for it to confirm that the new lifters are working and running. This will show when after starting the engine and it does not make a noise while running.
