How to check and adjust the valve clearances in a car?
To use the feeler gauge for valve clearance adjustment check if the clearances are incorrect, on some car engines, it is only a matter of turning an adjusting screw to put each one right. The clearance is correct when a clean feeler will slide into the gap with only moderate end pressure. If the gauge is a loose fit, the gap is too wide.
Where are the clearances on a car engine?
valve clearance is the clearance created on the valve that allows it to be moved in and out of the cylinder head to allow air or fuel flow into the combustion chamber. The action is usually made possible through the camshaft located above the sets of valves.

How do you check the valve clearances on a motorcycle?
Once you know which valves to measure first, use your feeler gauge to check the gaps. Set your feeler gauge to the size it should be (you might need to combine two or more blades), then poke it in between the cam and the bucket; you’re feeling for a slight drag as you push it in and pull it out.
What happens if Valve clearance is set to zero?
If the valve clearance was set to zero, the valve could theoretically still be set to close fully, but as the engine gets warm, the parts expand; with no gap, the valve wouldn’t close completely. That’s why valve clearances MUST be checked with the engine stone cold. How do I know when my valve clearances need adjusting?
What should the valve clearance be on a ZX 6R G2?
If you’re lucky, when you’ve checked the valve clearances, you’ll find they don’t need adjusting. The exhaust valves are the most likely to be out, but there is some tolerance; on my ZX-6R G2 for instance, the inlet valves should have a gap of between 0.11 and 0.19mm, while the exhaust valves should have between 0.22 and 0.31mm.
