Powerbuilt 10 Millimeter Jam Nut Valve Adjustment Tool, Slotted Valve Adjusting Stud, Honda, Nissan, Toyota, Japanese Vehicle Engines - 648827

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.

The tool works well to help adjust the valves very handy would buy again

It's very good, I really liked the tool, I was able to do the job quickly.

Worked as it should

Tool appears to be well built, it fits perfectly on the valves and gives plenty of space to loosen and tighten the jam nuts. As a warning, however, the tool will NOT fit the valves on a Honda k series motor. I tried to do the adjustment on my TSX but the tool is too large for the jam nuts. You’ll need the 10mm version for the k series and other Honda motors, so don’t make the mistake I made and double check what size the jam nuts are on your engine. Even so, I am satisfied with the quality and will purchase from this brand again.
