Best Engine Valve Train Tools of 2025

"I was able to disassemble and reassemble the heads off an old Chevy with this product. It worked well, although it was a bit small for larger valves. Overall, it’s excellent for a smaller engine."

"I bought this kit after getting a new head with my truck. I used it along with lapping compound and what we call 'bluing compound'. I found it easy to use and saved a lot of money. Just take your time with the process, and you’ll get a perfect seal."

"I lapped the valves on a Kohler 24 hp engine. The suction cups worked pretty well but had some trouble sticking when dirty. The included clamp was also very effective!"

"I really appreciate the functionality of this product. It reaches deep into smaller heads, but I did find that it breaks after a few uses. Initially, I thought mine was defective, but the replacement also broke after normal use."

"I used this for disassembling the valvetrain on my Subaru EJ series. There are specific compressors for Subarus, but I chose this one since it's not limited to a single application. I found it reasonably priced and it worked perfectly without feeling poorly built."

"I managed to complete a valve job on my Jaguar XJ6 and it worked great! I did have an issue with the top hinge rivet snapping after only getting through 13 of 16 springs on a Toyota engine. I had to replace the rivet with a bolt, but overall, it did the job."

"For the price, I can't really go wrong. All parts are well made for most DIY jobs. Each application is different; I ended up welding brackets to make things fit specific motors and bought some bolts and washers. Not a big deal since I can modify it for any motor I'm working on. This kit is great, but remember, 'universal' means some creativity is needed to make it fit."

"I found this tool to be great! It comes with everything I needed for the job. It worked smoothly when I was removing and installing springs. The spark plug compressor hose fit perfectly, and the valve seal installer with different sizes is fantastic. The only drawback is that they only provided three bolts, so I had to use zipties to secure one side. I wouldn't recommend using my own valve cover bolts, as one bent a little during reinstallation. Other than that, it's a great tool, and I'd recommend it for anyone working on a 1.6 Miata."

"The tool I received had no instructions at all. However, I have used similar tools in the past, and it works great for replacing a valve spring on a Mercedes without head removal."

"I have nerve damage that limits my hand strength, but this tool has been a lifesaver. It's extremely easy to operate, and I used a ratcheting wrench with minimal effort. I've successfully done 6 cylinder heads with it, and I love that it takes up less space in my toolbox."

"The directions were terrible, but the tool gets the job done. Just make sure to lube the bolt. I appreciated that it came with a spare bolt in case of stripping."

"This tool is straightforward and effective for changing springs, whether on or off the engine. If you're using it with the engine, ensure you have an air fitting to keep the valves up. It seems quite durable so far."

"As an engine machinist, I handle all cylinder heads for my shop. This product is not even close to what it should be—absolute garbage!"

"The tool worked fine initially, but broke after just five minutes. The mechanism failed, and now the case is coming apart. Missed return window unfortunately."

"I purchased this tool to help me remove the valve keepers in my 94 Dodge Stealth TT. It worked great for an amateur like me. Just a dead blow and this tool is all you need! It's very durable; I've used it several times with no issues. While I couldn’t use it to install the keepers, it definitely makes removal much easier."

"I used this tool to replace 24 valve stem seals on my 1987 Toyota Supra MK3. By using the 'rope trick', I avoided removing the head. It took a bit of time to master the technique, but this removal tool pops the valve and releases the keepers in about 2 seconds. Fishing the keepers from the magnet takes a minute, but it reassures me they won’t fly away. The tough part is reinstalling the keepers, which sometimes requires multiple attempts, but I'm very satisfied with the results considering the low price."

"This tool worked well for removing the valve stem keepers and springs, and it also excelled in reinstalling them. Watching a few YouTube videos beforehand helped me a lot. It's worth every penny, even for occasional use. It removes the keepers without launching them across the room, and makes the reinstall process feel effortless!"

"After researching several tools, I decided on this design and I'm really pleased with it. Although it was a bit tricky to get on and off, I eventually figured it out and it worked very well for a full-valve job on my 23HP V-Twin Kawasaki lawnmower engine. The real issue turned out to be a faulty fuel shut-off valve. The material feels heavy duty and the packaging was great. I would definitely recommend it."

"I found this tool much easier to handle than others that require pressing down or hammering. I was breaking a sweat with the press-down tool, so I decided to try this one. It turned out to be the best bang for the buck and I didn’t even have to work hard. I highly recommend it for valve springs outside the car."

"This was my first time grinding a set of new valves, and I have to say, this product worked perfectly. It made the job so much easier for me!"

"As someone who had never lapped a valve before, I found this set to be both functional and affordable. While the valve spring compressor didn’t work for my setup, I believe it would perform well for the right application. The lapping tools, however, were simple and effective, and I think they could handle much heavier use than I needed. I’d recommend this for anyone who needs a set for at-home use."

"I recently worked on a Hyundai 2.4L DOHC 16 valve cylinder head using the smaller tool from this set. I had to use a hammer to remove the keepers, and after a few, I ended up fishing them out with the smooth end of a drill bit. Nonetheless, most of the installation went smoothly. I decided to use a drill version for lapping to save time and energy. I also appreciated the nice color of the tools!"

"I initially gave this tool 4 out of 5 stars, as one of the rings over the keeper hole dropped off during my first use. I managed to reattach it with some Megagrey silicone, and it seems to hold well without hindering the tool's performance. Despite this, I’m still happy with my purchase. If I encounter any further issues during use, I will be sure to update my review."

"Overall, I found this kit to be excellent for removing and lapping valves. I've used it on small engines and even a compact 4-cylinder engine, and the parts are holding up well. The hand valve lapper is especially convenient!"

"I was disappointed with this tool as it bent immediately and I couldn't even remove one valve."

"I managed to put in the valve springs, and while it worked well initially, it started to bend after just 10 springs due to metal fatigue."

"This tool is a fantastic addition to my toolbox! The quality is impressive, and it comes with additional tools. Highly recommended for its value!"

"I found this suction cup set to be excellent for any task. The quality is impressive and the suction works great!"

"It took a bit of effort to get it to stick to the new valves, but overall, it performed as expected for lapping valves."

"Although I haven't used them yet, they seem well-built and of good quality."
