Re: I have tried so many ways of adjusting my honda valve...
You did not mention what engine you have, but on the vtech engines, the valve noise is usually a result of a worn camshaft and lifters. No adjustment will make it any better.

A sure sign that it's time for a valve lash adjustment is if your engine is making a loud clicking or tapping noise when starting up or if you experience a loss in engine power. You can find more details on the suggested adjustment frequency here. https://www.allstatepeterbilt.com/blog/valve-adjustments-explained
How To Check Tappet Clearance
Taking all safety precautions.
Make sure the piston is on TDC. ...
Make sure the engine has cooled down.
Loosen the lock nut of the rocker arm.
Now adjust the tappet clearance between the rocker arm & valve stem by tightening or loosing the nut below the lock nut.
To adjust the valve clearances, use a spanner or a socket wrench on the crankshaft-pulley bolt. Turn the engine in its normal direction of rotation until No. 1 piston is at the top dead centre ( TDC ) of the compression stroke .

you check clearance cam shaft.if your cam shaft big clearance.you need fix clearance.the noised your engine or valve any particular of that clearance can be taken your car really ticking very noised mom?before your rally worn out.
There is a specific procedure for setting valve clearance . I highly recommend getting a repair manual for the correct specs & procedure. The engine must be at TDC with the #1 cylinder on the compression stroke , that will allow you to adjust ONLY certain valves , then you have to turn the engine one turn to TDC again only now #1 will be on the exhaust stroke & the rest of the valves can be adjusted . it's important that you know the difference between the two !
-Open valve cover and check it out. It's bend or out of adjustment. If it's bend then has to replace the valve
that make noise. If it's out of adjust or gap is too wide
then just adjust to the correct gap. you should be good to go.
sounds like your have timing issues and the loud noise is known as a back fire if I am correct about you having timing issues. If I am correct I would recommend a new timing belt and related components. Also replace the spark plugs and you should have the valve clearance checked and adjusted. They need this every 60,000 miles and the timing belt should be replaced every 105,000 miles.
As a first course of action I strongly suggest that you take it in to any reputable mechanic and perform a valve clearance check. The clearance may be too far that's why it creates a noise. If that's the case then have a valve clearance adjustment.
You may want to replace the MAF (mass air flow) sensor too. If the MAF is faulty an erratic idle may occur and engine may stall. The MAF is located on the throttle body.
Hope this helps and thank you for using FixYa! Have a good one!
its hard to tell, sometimes they would..... but easy to check before hand, take the valve cover off and check valve clearance as if you were going to adjust the valves, if any valves have way too much clearance the valve is bent.. The valve spec is on a decal under the hood.
All you need is to adjust the valve tappet clearance back to the original specification. It is a time consuming effort and require passion to do it. You need to remove the top engine cover, set timing belt to top dead centre then adjust intake & exhaust valve clearance one by one. Rotare the cranckshaft 180 degree and repeat the valve clearance,. I would suggest to leave it to the expert.
