Review on 🔧 YourSME Valve Spring Compressor Tool for Ford 4.6L 5.4L 6.8L 3V, Comparable to OTC 6684 Rotunda 303-1039 by Greg Moore

This product does not fit Ford 5.4 3 valves. The handle with the top thread is not screwed in deep enough for you to screw the handle onto the tool. This means that for each valve you have to loosen and lift the camshaft so the other end of the tool is close enough to unscrew the knob. Spending an extra $10 on a smarter design will save you HOURS and a lot of frustration.
