Valve clearance settings?

Good morning,

I posted the specs for you below for your procedure. I also included pictures for the valve cover as well. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Okay, sorry it took so long.

Below is the procedure and some pictures for you.

Good morning,

I attached the procedure for you below for the valve adjustment.

Let me know if you have any other questions.

The material I have on the 1.0 S-Tec engine shows:
Engine Cold
Intake 0.15±0.02 mm (0.0059±0.0008 in.)
Exhaust 0.2±0.02 mm (0.00787±0.0008 in.)
Engine Hot (run until cooling fans cycle on, then shut off engine)
Intake 0.25±0.02 mm (0.0098±0.0008 in.)
Exhaust 0.3±0.02 mm (0.0118±0.0008 in.)

Procedure is to set the engine at TDC on the compression stroke of cylinder 1 as in the first image then adjust the intake valves on cylinders 1 and 2 and the exhaust valves on cylinders 1 and 3.
Then rotate the crankshaft one rotation and bring cylinder 1 to top dead center on the exhaust stroke as in image 2
Now you can adjust the intake valves on cylinders 3 and 4 and the exhaust valves on cylinders 2 and 4.

Hello,

Here is a video to show you how to use a torque wrench correctly with the engine torque specs and clearances in the diagrams below:

Hello,

There is no procedure for adjusting the valve lash on your vehicle. This is accomplished by hydraulic lifter/lash adjusters. In the diagrams down below I have included a description of the Variable Valve Actuator for your vehicle. I hope that this helps.

Thanks,

Hello again,

Okay, we have no listing for a 2009 Chevrolet Spark, they start in our reference manual at 2013. Do you live in the United States? Also, we have no listings in our reference materials for a Daewoo Matiz as well. Sorry.

Thanks,
Alex
