Review: 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.
