I called OTC and they sell a new version of this tool, same model. If you do a google search many stores will show the new picture. It is based on the Ford tool 303-567. According to them, all new sales should be the new version. It is uncertain if Amazon has old stock.
The new tool bends at 90 degrees instead of being straight, and has a raised area where the socket is placed (instead of being flat). There is much cam cap interference and it adds tons of frustration to an already difficult job. The tool may not even work when centered on the cam, you may have to offset it a bit to account for the obnoxious raised area.
You must use this new tool with a long horizontal 3/8 extension or the socket head will lock onto the cam cap. This is what happened with my 95 4.6L engine. It is less of an issue with the 32V engine but its still very awkward. I don't know about later years, but it is suggested for all modular engines. The tool got two stars because it works great on the center valves where there is no cam retainer.
These tools are designed by Ford. I don't know why they would change a good design into something that is practically unusable.

Amazon Verified Purchase
Buying this on Amazon was the cheapest I could find it. There's just no great deal to be had. You actually can install and remove the rocker arms without this tool, just using a screwdriver. But I wanted to have the correct 4V tool. The 2V tool works easier for the exhaust valves. The 2V tool is definitely cheapest on Amazon.
To use this tool correctly, you place it on the cams NEXT to the lobe, not centered over the lobe. Use the ratchet or breaker bar on the same side of the tool as you position the swivel foot, for the best angle, which keeps the tool from sliding on the cam and scratching it.

This tool will only work on a two (2) valve motor. It will not work on a 4.6. 4v (a 4 valve) motor. The advertizement says it will work on a 4.6.2v, 4.6.4v. or a 5.4.4v. However it says on the factory packaging it is for use on 4.6 2 valve ford motor.

Worthless tool.

I purchased the OTC Valve Spring Compressor Tool to replace the lifters on my 1999 Ford Expedition Triton V8. It worked great and the tool is well made.
