The valve lash settings, on your Caterpillar C9 diesel engine, should be set to .007. The valve lash may be slightly different depending upon the age and where of the valves.
There is no valve adj on a 4.0l it has hydraulic valve lifters.
Fatory lash for stock Chevy engines are zero lash. plus one, and one ONLY, full turn. If you have a solid lift cam that is not a stock cam and the lash soecs should have come with the installation instruction. Done properly there is absolutely no need to have the engine running with the valve covers removed to properly set valve lash. Get a good service manual and follow the instruction exactly.
how do you set timing on 2001 malibu 3.1
2.0 dohc is set with selective shim fit
On hydraulic lifter engines tighten the rocker arm adjustment nut 3/4 turn after you have found zero lash adjustment point. On an engine with solid lifters set then to .026 cold.
Valve clearance of Volvo f12, are set using a feeler gauge on the lash adjuster.
no adjustment!! set at factory.
You have to set the piston at Top Dead Center (TDC). I beleive the lash adjustment (valve clearance) is .004 to .006 in. That means thousandths. Once you have set piston at TDC (valve springs will not be compressed but extended on the compression stroke at TDC). You can now set the lash adjustment by loosening the set nut and bolt. You need a feeler gauge to do this. Set lash on both valves then recheck.
There is no lash adjustment on Pontiac engines. You simply torque the nuts down to 20 foot lbs.
the timing is set by the computer and cant be changed chilton dose make a repair manual for this car to tell you how to set valve lash
