Excellent tool my problem was resolved in minutes

Tool is excellent quality, worked flawlessly. Used to compress valve springs in an F150 4.6 3v in order to replace cam rockers and followers.

Tool was really tuff good tool

this tool works very well and affordable

I bought this tool while doing a engine swap on a 2012 Expedition,FOUND THE NEW/USED ENGINE HAD A BAD FOLLOWER,Used this tool with a new follower and it worked Perfectly!did not have to remove the cam.Installed and engine works great.

If you are buying this for a 4.6L 3V, this one works perfect for it. I originally bought the $46 amazon timing tool kit and the one in there I had to modify it twice. Don’t waste your time with other ones, this one was a total time saver.

There's definitely some serious quality assurance issue going on with the factory that's pushing out this product. The 5.4 3V variant MAY require you to grind the tip of the piece that goes on top of the valve spring, but you'll have to make absofreakinglutely sure that the tip itself is screwed in all the way before condemning the tool to the grinder. Here's what I want you to do, go ahead and absolutely buy this tool BUT keep a stone grinder bit handy that you can use with your drill. You can easily buy one of those bits at Wally world for just a couple bucks. If you find this to be too much of a hassle to make this tool work, then you seriously shouldn't be wrenching on cars. Literally took me 10 secs to grind the tip. I recommend this product. It's super sturdy.

I was looking to buy the OTC tool for this after reading how so many others broke this tool while using. However there were enough positive reviews that I decided to try and save some money so I took a chance on this brand of tool. I am very glad that I did. After removing and installing the roller followers 30 times (6 removal and 24 install) you learn what feels correct and what doesn't. Above all, be patient! This is a tedious process. Be careful to have the tool positioned correctly on the valve spring and in the correct pocket of the cylinder head for the valve spring to be pushed down. It is extremely easy for the tool to catch on the side of a cylinder head bolt boss and hang up. If you keep tightening it, this is when I think these tools can break. When positioned correctly, the amount of twisting force you put on the knob will feel the same for all valves. It if feels tight, then stop and figure out where it is hanging up. An inspection mirror will be extremely helpful to make sure the follower is put back in the proper position. Three times during this process, I didn't have the follower in the correct position and released the valve spring only to discover that I had to do it again on that valve to get the follower in the correct place. Other than that, don't hesitate to buy this tool over the other more expensive brand. It works!
