I'm fairly new to the s2000 community. I have recently acquired an ap2 DBW with 28k miles. After reading https://www.s2ki.com/s2000/topic/106...ners-dbw-cars/ thread, I learned that I needed to adjust my valves ASAP for fear of tight exhaust clearances leading to burnt valves. Last Sunday I got my balls together and I attempted to adjust my valves which I haven't done before. I did a lot of research and ultimately used robrob's DIY and to my knowledge set my valve clearances to your recommendations. Intake @.009 and Exhaust @ .011.

From the adjustment I have found that a few of my exhaust valves were on the looser end like .012 while half of them were with in spec. On the intake side there were more loose valves compared to the exhaust side. However, I never really paid attention to how my engine sounded before I adjusted them. I took my time and made sure I did everything precisely.

I have attached two video links below.

Does it sound normal? or is the ticking excesively loud? Not too sure if it got louder or not. Hopefully not!
I just want to know that I didn't screw up anything and that everything sounds normal !lol

IF anyone wants to chime in please feel free to do so!

Thanks a LOT!!!

 

Links are broken.

 

Fixed youtube links. It works now

 

Without a before it's hard for me to tell anything. At the loose end of the tolerances there's more clicky than if the gap is too small. I think I had one was "0.0115" and I left it alone since they tighten as they wear.

hmmm... I know I never really paid attention to how she sounded before I adjusted the valves.

 

The valvetrain on these cars is fairly audible to begin with, so as long as you feel you properly felt for drag with your feeler gauges and tightened the nut making sure the screwdriver didn't move, then you should be all good. If you have any doubts, you should recheck them. I just did this last weekend as well. My first time, but the car's 2nd. It was done 16k miles ago. I have a 2007 and all my exhaust valves were tight. Only 1 intake valve was fairly loose. After I put everything back together, mine sounded similar to yours and it's running beautifully. I was having issues with what felt like some VTEC power loss and this cleared them right up. Very happy with the results and a pretty rewarding procedure for someone who doesn't do this kind of work, ever.

 

Some valves are tricky to adjust, I've found that the sound gives it away. Cylinder 1 is the easiest to do perfect, I use that as my baseline. Whenever I'm not sure I adjusted a valve properly I wiggle the rocker, and compare it to the way the rocker pivots on a known good one. If it's off you'll feel it move more or less and the sound when the rocker taps the valve stem will be different.

 

The injectors make a ton of noise. Try to concentrate and move your head about the engine bay to differentiate between the different noises and where they come from. Im sure you took the job seriously considering you went to the trouble of taking the valve cover off to perform surgery so dont be paranoid. Mechanic stethoscopes are cheap and theres probably someone close to you with an S you can listen to for comparison if you still feel bothered.

 

Your engine sounds very similar to mine after the valve adjustment. At first, I had doubts that I did something wrong. But many folks here were able to confirm that my engine sound OK to them.

Here's my post with the sound clip.
