I read the other 2star review, the reviewer said he/she received a 12mm tool instead of 10mm. Despite that single incident, I went ahead and ordered this tool because I know there was some many five stars for this thing.

So I received the tool and bought my Craftsman feeler gauge from my local Sears. Opened the valve cover and start working. My first valve adjustment job didn't went so smooth. I figured having this valve adjustment tool would save me some time and a lot of hassles, but it wasn't. My tool said 10mm on it's package and also marked 10mm on it's body. It is in fact a 12mm in my case. It was useless and fortunately I have my ordinary screwdriver and wrench to finish the job. Put the valve cover back and cleaned my hands.

I was quite surprised about this because it received so many five stars. Amazon gave me a refund without actually returning the tool which save me a trip to the post office. not bad

Check the size before you open your valve cover and check out the pictures that I have uploaded in the Gallery. Thank you for reading

I have owned a number of Hondas and have performed valve adjustments using just a 10mm box end wrench
and a screwdriver successfully. Until I got the Honda S2000, there is just no way to fit in a 10mm wrench
on the jamb nut. This tool fits the bill perfectly, saving a lot of time and frustration.

If I had one improvement to make, it would be to change the screwdriver handle from a straight handle to
a "T" handle. That way you have more precision in the angular adjustment, as each adjustment step is
like 5 degrees for best accuracy.

The last valve clearance I did - did it with a standard non-adjustable 10 mm wrench and flat-head screwdriver. Had misplaced my valve adjustment tool.

On my Honda Accord - this was a HUGE PAIN! The exhaust valves were pretty straightforward, no real obstructions. But for the intake valves - fuel rails and other stuff was in the way, so using a standard wrench was a tremendous pain and really time consuming. Without this tool, it's really easy to move the tappet screws and be off by just a bit, and have to re-do the valve. This eliminates most error.

Really, if you're going to do your own valve clearance adjustments, do yourself a BIG BIG favor and spend the 14$ and get one of these. You'll cut your job time in half.

Lastly, I had seen a few one star reviews saying they got a 12mm tool. I can't speak to these individuals, it may well be true. 12mm tools do exist for valve adjustments (but are made by different companies it seems, or at least rebranded). Right when this arrived, I tested it on a 10mm bolt, and it fit perfectly. So, what I got was 100% a 10mm tool.

I used this tool on my 2006 Honda Accord and 2006 Honda Pilot to adjust the valves and it made the job soooo much easier! I highly recommend it.

Very handy tool. It keeps the screw right where you want it while tightening the nut. This is a big time saver.

This tools makes adjusting valves CAKE. This was the first time I have ever done a valve adjustment on my GSR motor. Very simple. Why pay $50 for the snap-on tool, when you can get this tool for $12.

Yea, it may look flimsy, but go ahead and adjust valves on a Honda/Acura with this tool and you will be more than satisfied. I wish I had owned this many years ago! Makes the job move faster than plain old wrench and screwdriver.

This tool works quite well on the Integra GSR DOHC VTEC valve lash jam nuts. It is certainly easier than using a seperate screwdriver and wrench. It is well worth the price.
