Great value. Build quality is very good. Size fits pretty well in hand. Great for taking out valve keepers when I rebuilt my cars cylinder head

Best tool I’ve found for inserting or removing valve keepers. Saves a lot of time and frustration using those giant C style clamping tools. I would recommend this to any one.

Worked great on my e36 head, was a bit worried about damaging the aluminum head but all went well! 5 stars!

NOT cheap junk that disintegrates when used. Works perfectly and will continue to do so until the end of time. This is a necessary tool for valve springs that are recessed into the head and this one has magnets that will hold up and continue to work. Cheap foreign fakes just fall to bits (which then contaminate the motor!) and are totally worthless. Been there and know better now so learn from my error, pay a tad more and get a tool worth having and that will do the job. This one!

Using hammer to remove keepers is fine, to install is different, i tried hammer technique but doesn't go well on the install. Keep the head at a height where by you can press down using your weight. I didn't perfect the install technique, but i think if you put the keepers in the spring cap and push that down on the stem with you fingers just getting it started may be the way, then finish with tool, pushing down by hand, using your weight. Overall its a great tool, really fast for removing the keepers. I bought it for one job, i may never use it again, but it saved time. This was done with heads off the car, was doing gaskets also.

Mine came with instructions. Small leaflet. But you also must do some thinking as well when using these. There are two drivers & two strikers. I used the larger tool till the snap ring retaining the collet extractor/installer popped loose. There's a lot of spring pressure involved to fix that & I was mid-job?Then I looked at the other smaller tool, it ended up being the smaller collet extractor/installer chucked into the larger striking unit that did the trick. I have no idea why but that combo ended up being the right striking face & right extractor diameter so remove & install on a 16v SR-20 (Nissan) engine. Those eight tilted towards the intake with cylinder head installed are near impossible with a bolt-on spring compressor bar, lever & fixtures bolted to the head. This tool works, you just have to Mix n' Match the strikers & collet remover/installer ends. Saves having to pull the head to finish. What is that worth? I'd say $250. : )

Saved me a lot of heartache when I had to change valve springs on an RB25DETS1 without removing the head. Also used this to prep my 2JZ. When installing stiff valvesprings I just bonk the tool with a 3lb sledge, works fine.

100/10 would recommend i dont care what the bad reviews say the tool makes it a breeze removing the springs to change the seals and almost as easy to reinstall just takes some practice!!! The key is keeping it straight with the valve angle and i think thats why people leave bad reviews because they cant figure that part out but i know some tools might be better on more basic/older engines but if you have a newer engine like a 2000s and up some have recessed valves that make it impossible to remove the springs unless you have the head off this tool allows you to keep the head on and its very simple to use im using it on a 4cylinder Toyota 2.4l engine and its the only tool that will work with the head on! Also make sure you use an adaptor to hook up an air compressor through your spark plug hole to keep the valves from falling down way better than the rope method i have seen people use and i would also recommend you only take off 1 spring per cylinder at a time too minimize the risk of a valve dropping into the cylinder!

acostumbrado a remover los retenedores con mi herramienta arcaica ( tipo compresor C ) , esta herramienta me ha ahorrado tiempo al retirar las valvulas y en el reensamblaje posterior , la recomiendo ampliamente.

The item works well to remove valves, however an important note for anyone new to engines, this does not work on the BMW N47 engine as I attempted to use this 😂 (not fault of product) extracting keepers work however block gets in the way for putting them back in. However for just removing keepers this tool makes it super easy and the magnet prevents you from losing keepers. Worth the money especially if you use it for correct engine 😂

Outils intéressant mais pas applicable à tout véhicule, dans mon moteur 1.6 thp ne convient pas, néanmoins je m'en servirai sur d'autre moteur.

I only used the metric device just this weekend during valve stem seal replacements. Super easy to use on stock valve springs in a Toyota inline 6 cyclinder engine. It was much harder years ago on a similar engine with aftermarket valve springs.Having a larger end on the handle might help the user get their weight behind the tool when installing the collets back in. Then again, taller, heavier-set users with more upper body mass will find it relatively easier to lean into the tool when installing the retainers.The springs within the installation attachment were somewhat gritty but this was eased with some motor oil and rapidly pushing on the sprung tip many times before use.When installing the collets back into the retainer, valve and spring assembly on the Toyota engine, it’s best to place the collets into the retainer and place the retainer on the valve before using the tool. It doesn’t work if you put the collets on the tip of the installation tool and push down on the retainer, valve and spring assembly.

I've been using the old clamp style spring compressor to remove/install valve springs. This tool makes the job so much quicker. I was able to remove 16 valves in a couple of minutes. Just place the tool and give it a good whack and the keepers stay in the tool instead of falling on the floor. Installing the valve springs is allot easier too. I tried setting up the tool and keepers and gave it a tap with a dead blow hammer. It's a beautiful thing when it works but everything has to be lined up perfectly. I was able to hand press the valve springs in which was okay for stock valve springs. I have a set of performance valve springs that I will try with this tool. I'm hoping the new springs aren't too stiff for this tool to work.One of the best advantages of this tool is that you can remove the valve springs with the head still on the car. But keep in mind that you need to hold the valve in place while the spring is out. If it drops then you are removing the head. Be careful guys!
