  Q: How to replace the Lash Adjuster on Chevrolet Metro?

  A:

  First disconnect the negative Battery Cable then remove the rocker-arm cover as the first step to start replacing the Lash Adjuster. The first step requires removing both the Timing Belt and Camshaft from the situation. Extract the six hydraulic lash adjusters that are inside the Cylinder Head. Engine oil installation requires a pouring step through Camshaft journal holes which must drain out from the Lash Adjuster bores oil holes. The Lash Adjuster needs engine oil applied for installation onto the Cylinder Head. Before placing the Cylinder Head Camshaft into position, apply engine oil to the Camshaft journal along with all cam surfaces and direct the Camshaft timing gear pin hole to remain in the lowest position. Apply gm p/n 12346240 or an equivalent to the mating surface of housing number 1 and number 3 facing the Cylinder Head while sliding engine oil on each component against the Camshaft journal. Fit housing number 1 to journal number 1 but leave it untightened before placing the housing assembly opposite the Timing Belt side of the Camshaft and Cylinder Head. The stored arrow on the housing should face the desired direction. The Camshaft housing bolts must receive a thin layer of engine oil before they are bolted onto the Camshaft journal. Secure the remaining two Camshaft housings (2 and 3) onto the Camshaft journals through housing bolts while progressively tightening them to 11 nm (97 inch lbs.) during three to four bolt-tightening sequences. Before complete insertion add engine oil to the outer edge of the Camshaft oil seal and push the seal until it aligns with the housing face. After applying oil to the mounting holes of the housing bolts, install the Camshaft while replacing the Timing Belt and reattaching the rocker-arm cover.
