🔧 PQY Engine Valve Spring Compressor Tool - Compatible with Ford Mustang GT 4.6L 5.4L 3V Explorer Trac - Magnetic Screw Retainer (Blue) Review

Tool will not fit 4.6L 3V spring. The lock cap seating hole is too large and does not sit on the lock cap but on the spring itself. The main pin is too short and bottoms out before the spring compresses. For springs that are more in the center of the cylinder head, the tool won't even fit due to the gap between the spring and the cylinder head casting. Reconfigure and buy the original.

Tool does not go in deep enough to engage or disengage valve stem keys. The key access cutout should be higher. Maybe double the height. I used a washer as a spacer and it helped. I bought a longer screw to fix the problem. You just have to be careful not to drop it and push the valve into the cylinder. I order several different valve spring compressors, this one needs improvement but it's a good concept. 2005 Ford F-150 3 valves

When I first received this tool one of the parts was wrong but I contacted the seller and he fixed the problem by sending me a new part that was important to him Works perfectly on my 3V Ford 5.4. Got a new tool part that worked great and was able to complete the task of replacing the valve seal, tappets and rocker. I am very pleased with the tool (which worked much better than the Ford recommended tool) and pleased with the seller for the FAST resolution of the problem. I will certainly do…

The product arrived quickly and corresponds to the description. Sturdy instrument frame design, beautiful anodized finish and fine workmanship. But that would be a 5 star rating, but also close to a 2 or 3 star rating, see below for details. The hardware leaves a lot to be desired, the bolts for attaching the tool frame to the cylinder. The head is not long enough to properly engage the aluminum cylinder threads. Head, the included screws only engage 3 or 4 threads. Instead I used cam cap bolts
