Greetings viewers, Dora the Explorer here. I’ve had a couple requests for a video on valve adjustments, so here’s a guide for a valve adjustment on a Honda engine. Different manufacturers have different ways of going about this, but this is the basic setup for a Honda.
Honda engines for the most part have a solid valve train, which means that you adjust the valves periodically, normally only when it’s noisy or when there’s some kind of issue. It does help the engine run a little bit smoother, but it’s rarely done as a repair; it’s more of a maintenance item.
Remember, the valves that do not need to be adjusted are hydraulically actuated. Hydraulically actuated valves don’t get adjusted by design.
When you’re ready to perform the valve adjustment, make sure the engine is as cold as possible. Remove the valve cover and inspect the wires for any signs of cover damage, as this could be a sign of an underlying issue with the gasket.
Next, take out the spark plugs. Keep in mind that Champion plugs are not recommended for Honda engines. Use NGK or Nippon Denso spark plugs instead.
Now, on to the valve adjustment itself. Remember that attempting the valve adjustment if you’re not comfortable doing it can lead to damaging the valves. But, a good valve adjustment can make the engine run exceptionally well.
For the adjustment, you’ll need feeler gauges. The exhaust valves are adjusted with the larger feeler gauge, and the smaller one is for the intake valves. Make sure to keep track of which is which, as they are different.
When adjusting the valves, it’s crucial that the engine is cold. The best time to do this is first thing in the morning when the engine is cold.
Once the engine is cold, you need to be able to turn the engine over. Use a wrench on the power steering pump to turn the engine over. The engine must be at the base circle of the camshaft for the adjustments.
To adjust the valves, place the feeler gauge in between the rocker arm and the top of the valve stem. Make sure there’s a little bit of drag when pulling the gauge through. Repeat this process for all the valves, ensuring their accuracy for smooth engine operation.
Adjusting valves is an acquired skill that takes time and practice. You may need to attempt it a few times to get it right. Once you master this skill, you’ll have a smooth-running engine with improved performance. As always, for more automotive tips and guides, visit my website.
What is valve adjustment and when is it done?
Valve adjustment on a Honda involves adjusting the valves periodically, normally only when they’re noisy or when there’s some kind of issue. It is more of a maintenance item rather than a repair. The valves that do not need to be adjusted are hydraulically actuated.
When is the best time to do a valve adjustment?
The best time to do a valve adjustment is when the engine is cold, preferably first thing in the morning.
What tools are needed for valve adjustment on a Honda?
For performing valve adjustment on a Honda, you will need a feeler gauge, a wrench to turn the engine over, and a valve adjustment tool for loosening the nut and turning the valve, though a regular screwdriver and a wrench can also be used for the same purpose.
How is valve adjustment done on a Honda?
To adjust the valves on a Honda, the engine should be cold, and the valves should be on the base circle of the camshaft. The feeler gauge is placed in between the rocker arm and the top of the valve stem. The goal is to achieve a little bit of drag when pulling the feeler gauge through, indicating the right thickness.
What precautions should be taken when attempting a valve adjustment?
It’s important not to attempt a valve adjustment if you’re not comfortable doing it, as getting the valves too tight can lead to damage such as overheating and cracking. Valve adjustment is an acquired skill that requires practice and precision.
