    Q:
    How to keep lash adjusters and pushrods in order during installation on Buick Century? Posted by Customer
    A:
    Keep lifters and pushrods in order! This is absolutely necessary for installation, since these parts have differences which could result in engine damage if not installed in their original positions! Remove intake manifold, valve covers, rocker arm assemblies and pushrods. Remove the valve lifter guide retainer bolts, the retainer guides and valve lifters. Disassemble by removing the retainer ring with a small screwdriver, pushrod seat and oil metering valve, plunger and plunger spring, and check valve retainer from plunger, then remove valve and spring. After lifters are disassembled, all parts should be cleaned in clean solvent. A small particle of foreign material under the check valve will cause malfunctioning of the lifter. Close inspection should be made for nicks, burrs or scoring of parts. If either the roller body or plunger is defective, replace with a new lifter assembly. Whenever lifters are removed, check as follows: Roller should rotate freely, but without excessive play. Check for missing or broken needle bearings. Roller should be free of pits or roughness. If present, check camshaft for similar condition. If pits or roughness are evident replace lifter and camshaft. Assemble by coating all lifter parts with a coating of clean kerosene or diesel fuel. Assemble the ball check, spring and retainer into the plunger. Install plunger spring over check retainer. Hold plunger with spring up and insert into lifter body. Hold plunger vertically to prevent cocking spring. Submerge the lifter in clean kerosene or diesel fuel. Install oil metering valve and pushrod seat into lifter and install retaining ring. Prime new lifters by working lifter plunger while submerged in clean kerosene or diesel fuel. Lifter could be damaged when starting engine if dry. When a rocker arm is loosened or removed, valve lifter bleed down is required. Lifters must be bled down as possible valve to piston interference due to the close tolerances could exist. Before installing a new or used lifter in the engine, lubricate the roller and bearings of the lifter with No. 1052365 lubricant or equivalent. Install lifters and pushrods into original position in cylinder block. Install manifold gaskets and manifold. Position rocker arms, pivots and bolts on cylinder head. Install valve covers. Install intake manifold assembly.

    Q:
    How can you diagnose and address issues with hydraulic lash adjusters in V8 engine on Oldsmobile Cutlass? Posted by Customer
    A:
    In general, hydraulic lash adjusters are rather durable and do not require much attention to be paid to them. A noisy adjuster can be checked while the engine is running by putting a section of hose or tubing in contact with each intake or exhaust adjuster and listening to what is at the other end. As for the other ideas, touching each of the valve spring retainers with the finger, after the rocker cover has been unbolted, would lead to the feel of a bad adjuster through the shock as the valve seats down. If so, noise may be due with dirt got between the plunger and adjuster body when adjustments are correct. To get rid of the adjusters you have to eliminate the intake manifold with the valve cover and then, with the help of a lift rod pusher, you can pull each push rod out of the cylinder block. Where possible a special tool can be used to pull out the adjusters or a sharp scribe can be used to force up the adjusters instead using pliers on the adjuster body. Often, stuck adjusters can be released through the use of carb cleaner around the body of the adjuster and gently pumping the adjuster. It is also essential to store and label all the adjusters such that reinstallation of each adjuster is not mixed up with another. Once each of the adjusters is cleaned, one should look for either nicks or gauges, and if either of the two is present then replacement is required. The bottom contacting camshaft should be inspected for scratches as well as nicks and adjusters which should be replaced in case they show convexity due to wear. On the installation of the adjusters proper care must be taken in that they must be well covered with 'Molykote' or any equivalent product if the original adjusters are to be used again, they must be fitted to proper bore. Finally, replace all the valve parts and the covers, the valve cover, and the intake manifold.

    Q:
    How do you determine the extent of cam lobe wear before removing the camshaft for the 1995 Chevrolet Blazer? Posted by Customer
    A:
    To determine the extent of cam lobe wear, position the number one piston at TDC on the compression stroke, remove the valve cover, and loosen the rocker arm nuts to access the pushrods. Then, mount a dial indicator on the engine, position the plunger against the top of the first pushrod, and zero the dial indicator. Slowly turn the crankshaft in the normal direction of rotation until the indicator needle stops and moves in the opposite direction, indicating maximum cam lobe lift. Record this figure and repeat the check for each valve.
