Why do Hondas require valve adjustment?
The importance of correct Honda valve clearances can’t be over-stressed, as it can directly effect the performance and life of the engine. If the valve clearances are excessive, then the efficiency of the engine is reduced because the valves open later and close earlier than they were designed to.

What should valve lash be set at?
If the lash were correctly specified, the valve would open where indicated with a lift of about 0.011″ and a velocity of about 0.0007″. The valve lash should be about 0.012″ not 0.026″. Using the correct lash increases the seat-to-seat duration by 32 degrees, with only a small change in the 0.050″ duration.
What happens if you have too much valve lash?
Too much or too little valve clearance can result in poor performance or a rough idle because the engine can’t “breathe” normally and operate at peak efficiency. Too much clearance means the valves will likely clatter and, over the long term, cause damage to the valves, camshaft lobes or rocker arms.

To do that on a four-cylinder, eight-valve engine, use the rule of nine. Counting from the front of the engine if number eight valve is fully open, subtract eight from nine and the answer is one, so adjust the clearance on valve number one. If number six is closed, then adjust number three and so on.
What happens if engine valves are to tight?
If there’s too little valve clearance, the valves won’t fully close, causing excessive heat, and the engine will lose power.
What can result from valve train valves being too tight?
too tight can lead to loss of power do to valve timing, especailly on the exhaust side, since that valve grows more than the intake valve, excessive can lead to valve damage since the valve will bounce when closing because it doesn’t maintain even pressure.

How do you get zero lashes?
Zero lash is defined where all the clearance has been removed between the lifter, pushrod, rocker arm, and the valve tip with the lifter on the base circle of the lobe. Zero lash is easily found by slowly tightening the poly lock while twirling the pushrod in between your fingers.
What are symptoms of incorrect valve lash adjustment?
Common symptoms that your valves are out of adjustment
- Your engine makes loud tapping or clicking noise. One of the common symptoms of valves that are out of adjustment is if your car engine keeps making loud tapping or clicking noise.
- Overheating.
- Increased fuel consumption.
- Pre-ignition issues.
Do valves get tighter or looser?
With exhaust valves, the clearance can become tighter over time as the valves or valve seats wear down, diminishing the clearance, known as the lash, between the valves and the valve train components.
What happens if valve lash is to tight?
If the lash is too tight, the intake valve may hang open. Some engines have the valve-lash adjustment on the pushrod, like this early Hemi. Here’s a rocker arm with the adjustment on the pushrod end. “You can also burn a valve if it’s not fully seated,” adds Godbold.

How do I know if I have tight valves?
If the valves are loose a trained ear can usually hear them. If the valves are tight, they will not fully seat, but they will sound just fine. This (tight valves) effects performance but what is worse is the valve sheds heat when it hits the valve seat. If it is too tight you can burn valves and or seats.
What happens if valve lash is too loose?
If it too loose, the valve will open later and close earlier. The effect of setting the valve lash too tight can result in the valve not fully closing on the seat. This will allow cylinder pressure to escape along with high-temperature combustion gases.
