How can a noisy valve lash adjuster be isolated and what steps should be taken for inspection and reinstallation in four cylinder engine on Pontiac Firebird?

A noisy valve lash adjuster can only be felt when the engines are idle, by putting a length of hose or tubing near each position valve while you listen at the other end of the tube. A noisy valve lash adjuster is most likely to be caused by wear at the adjuster foot and camshaft lobe, wear, or contamination of the internal parts of the Valvetail. Start by unplugging the rocker arm cover then the intake manifold, as well as the pushrod cover. Relax the nut of the rocker arm and twist the rocker arm from the pushrod to take it out and should in a case whereby many pushrods are removed, they should be placed in an orderly manner so that can be replaced in a rightful manner as they were used. Much like previous models, for later models that have roller adjusters, the pushrod cover studs, the adjuster guide retainer, and the adjuster guide must be removed. If the adjuster cannot be removed easily use a special lash adjuster removal tool, do not use pliers or any other object on outside of adjuster body can damage the adjuster. However, if the adjusters are to be reused a mechanism has to be designed to store them systematically to facilitate reassembly in their precise locations. Every adjuster should be cleaned and dried and should further be checked for any flat spots; if there is any adjuster that is worn concave, scratched or galled the entire set of the adjusters and the camshaft should be replaced. If the adjusters are still serviceable they can be reinstalled in their original locations and coated with moly based grease or engine assembly lube. The remaining installation steps are done in the reverse sequence as used during uninstallation.

How can a noisy lash adjuster be isolated and what steps should be taken for removal and reinstallation in 3.5L, 3.9L V6 engine on Pontiac G6?

A noisy lash adjuster can be isolated when the engine is idling by using a mechanic's stethoscope or a length of hose near each valve while listening at the other end, or by removing the valve cover and touching each valve spring retainer with the engine idling to feel for shock if a adjuster is defective. Common causes of noisy adjusters include dirt trapped inside and insufficient oil flow, viscosity, or pressure, so it's important to check the oil for fuel contamination, correct level, cleanliness, and viscosity before concluding that the adjusters are at fault. To begin removal, take off the valve cover(s) and intake manifold, then remove the rocker arms and pushrods. Next, take out the bolts holding the roller adjuster guide to the block and remove the two guides, marking them for their original sides. Adjusters can be extracted using a special tool, a small magnet, or fingers, and a machinist's scribe can help pull them out by positioning the point under the retainer ring. Caution is advised against using pliers unless intending to replace the adjusters, as they may damage the precision machined components. Store the adjusters in a clearly labeled box to ensure they are reinstalled in their original locations, and clean them thoroughly with solvent, drying them without mixing them up. Inspect each adjuster for scuffing, score marks, or uneven wear, and check the rollers for wear or damage, ensuring they turn freely. When reinstalling used adjusters, place them back in their original bores, soak new adjusters in oil to remove trapped air, and coat all adjusters with moly-base grease or engine assembly lube before installation. Finally, install the push rods and rocker arms, and complete the installation in reverse order of removal, then run the engine to check for oil leaks.

Pontiac Lash Adjuster maintains the valve clearance within the engine to a tight ratio to enhance easy reliable engine rhythm. Pontiac based its fame on vehicles that have a planted feel due to the wide track design and reward drivers with high steering sound through loud exhaust and non-apologetic body lines. Performance was never an issue for Pontiac; therefore, each sedan or wagon was produced with a nose that was designed to perform as well as gauges in the cabin where the angle was angled towards the driver. Since its initial straight six cruiser models to its subsequent V8 bruisers, Pontiac has remained committed to a basic idea of high-spirited acceleration at affordable costs and appearances that demonstrated so well in school parking lots as they do at the Saturday night stoplights. Drivers were fond of the feeling of confidence that these machines gave them in the event of merging fast or turning corners. The Lash Adjuster is a small oil-filled chamber that swells and contracts with the pressure changes to ensure that the rocker arm always rests at the correct height. Since the Lash Adjuster is always correcting clearance, it eliminates metal clash and slashes that would otherwise creep into the valve train under long highway hauls or on cold morning starts. Using hydraulic force to open the Lash Adjuster is also known to aid the engine in burning fuel more cleanly, enhancing mileage and cutting emissions without requiring the driver to switch habits or throttle baby.
