Review on Complete Ford 4.6L/5.4L/6.8L 3V Engines Repair Tools Set - Valve Spring Compressor, Crankshaft Positioning Tool, Cam Phaser Holding Tool, Timing Chain Locking Wedge with Crankshaft Pulley Bolt by Amy Cook

Very disappointed. I used a crankshaft positioning tool to align my 2007 5.4 3v engine. After leveling with this tool, the engine was not in time to sound like a cylinder was open when it was flipped. A fairly good tick is heard, and then a slight crunch before shutting down. I could never understand how I screwed up the deadlines. I thought I did everything right. After removing the heads and finding two bent valves (outlet #4 and inlet #8) I realized something seriously had gone wrong. It took me a while to understand that. The crankshaft positioning tool will be off by about 10 degrees. How should I know? I realigned the engine at top dead center, checked the piston, crank position and pressed the harmonic balancer to check the mark. Right to the point. Then I tightened the tool in the picture above and found that it slides right under the bolt. Not even close. I ended up buying 2 new valves, 2 head gaskets, 2 exhaust manifold gaskets, exhaust manifold bolts and the list goes on. I would NOT recommend using a crankshaft positioning tool unless you have the cash to burn it. I will return it and make sure they fill the ear. To be honest, a spring compression tool is priceless. I used it to install 24 valves twice and although it bent every 5th valve I was able to easily bend it back into place. The cam phaser lock tool also worked great. I didn't need the cheese slice thing.
