• Q: How to service and repair the exhaust and Lash Adjuster on 2004 Chevrolet Malibu?

  A: To service and repair exhaust and Lash Adjuster, start with the removal of the Camshaft cover and the upper Timing Chain Guide. After that, make sure to install the Camshaft sprocket holding tool (J 43655) and unscrew the intake as well as the exhaust Camshaft sprocket bolts, discarding them as well. Slide the cam shaft sprockets forward and mark the bearing caps so as to be fitted in their original positions. Precede to remove each bolt on each cap a turn at a time until no spring tension is on Camshaft after that remove bearing cap, exhaust Camshaft, roller following on the Camshaft, and the hydraulic element on lash adjusters. For installation, turn the valve tips and install the hydraulic element lash adjusters and then the Camshaft roller followers where the alignment notches align with the Camshaft sprocket. While assembling (install) the exhaust Camshaft and the Camshaft bearing caps, tighten the Camshaft bearing caps with 3 turns increments until seated, then a final torque of 10nm (89 inch lbs). Next, fit Camshaft sprockets onto camshafts, tightened new Camshaft sprocket bolts by hand, and remove the Camshaft sprocket holding tool (J 43655). Finally, you should tighten the bolts of the Camshaft sprocket to 85 nm (63 ft. Lbs.) + 30 degrees (precession), after which you need to install the upper Timing Chain Guide; then, with the torque 10 nm (89 inch lbs); install the Camshaft cover.
