Pontiac Fiero Lash Adjuster
The Terminator Lash Adjuster in Pontiac Fiero models has the primary role of moving the valves closer to the camshaft to enable easy running of the engine and bring down the cases of wear thus enhancing the life of the engines. This component also known as tappet turns the rotation motion of cam shaft to linear movement needed to open the valves. Several types of Lash Adjusters have been used in the Pontiac Fiero vehicles, namely, Solid, Hydraulic and Roller types. Another type of Lash Adjusters known as the hydraulic Lash Adjusters has special features that can vary clearance depending on the amount of oil pressure, thus not requiring much adjustment. These tappets are known as roller tappets they are preferred in modern applications due to the lower friction and efficiency. The decision making of Lash Adjuster type in the construction of Pontiac Fiero cars indicates improvement in Engine mechanism and power output.

Pontiac Fiero Lash Adjuster Parts Questions & Experts Answers
- Q: How can you isolate a noisy valve lifter and properly replace or clean it in four cylinder engine on Pontiac Fiero?A: To isolate a noisy valve lash adjuster, place a length of hose or tubing near each valve while listening at the other end, or remove the rocker arm cover and touch each valve spring retainer with the engine idling; a defective lash adjuster will be noticeable through the shock felt at the retainer as the valve seats. The most common cause of noise is dirt trapped between the plunger and lash adjuster body. Begin by removing the rocker arm cover, then loosen both rocker arm bolts at the cylinder with the noisy lash adjuster and rotate the rocker arms away from the pushrods before removing the pushrod guide plates and pushrods. Next, take off the Intake Manifold and the pushrod cover. Unscrew the pushrod cover studs to remove the lash adjuster guide retainer and then the lash adjuster guide, keeping them in order if multiple guides are removed. Lash adjuster extraction can be done using a special hydraulic tool, but often a small magnet or fingers suffice on newer engines without varnish buildup; a small scribe may also help, but avoid using pliers unless replacing the lash adjuster to prevent damage. Store the lash adjusters in a clearly labelled box to ensure they are reinstalled in their original bores. Replacing a worn lash adjuster is generally easier than repairing a defective one, as internal components are not sold separately. If cleaning a dirty lash adjuster, disassembly may restore normal function. When installing, ensure lash adjusters are placed back in their original bores, coating each foot with moly-base grease or engine assembly lube, and lubricate the bearing surfaces of the lash adjuster bores with engine oil. Install the lash adjusters with the oil orifice facing the front of the engine, followed by the lash adjuster guides and retainers. Reinstall the pushrods, guide plates, rocker arms, and retaining bolts, ensuring each pair of lash adjusters is on the base circle of the camshaft before tightening the bolts to the specified torque. Finally, reinstall the pushrod cover, intake manifold, rocker arm cover, and air cleaner.
