Easy Honda Accord valve adjustment
Great product and good quality for the price. I had a leaking valve cover gasket on our '14 Accord and thought I would check the valve clearance while I had the valve cover off. I purchased this tool ahead of time and I'm glad that I did. The valves did need to be adjusted and there are 16 valves to do. Some valves took several adjustments to get in spec and I went though the procedure twice to double check them all. The job can be done with a screwdriver and a 10mm wrench, but this worked so well and easy. I didn't have to worry about stripping the screw head or the locking nut and I was able to get good torque on the nuts. Recommended if you have a valve adjustment to do.

Necessary tool for valve adjustment!
I would recommend this tool when doing a valve adjustment. Instead of using 2 tools, it's built into one for easy adjustments on the fly. I did my first valve adjustment and this tool was a life saver. I think the process would have taken a lot longer without it. The tool looks sturdy and it would likely last a long time. Two thumbs up for me.

Great for Honda engine
It is used to adjust valve clearance for my Honda Civic 2007. It’s worth every penny as It helps to reduce my time on working on my car. The size of the valve nut is 10 mm for Honda. The quality is great. Remember to use a feeler gauge through the process to make sure everything is within manufacturer’s specs.
