DAYUAN Pro Cylinder Head Service Set Valve Spring Compressor Removal Installer Kit

i bought this for my dads birthday as it was on his wish list, i was hoping for something good quality for the price. i opened it up to check everything was okay before gifting the present and realised half the pieces weren’t in place. i just assumed they had fallen out of place in shipping so i tried using the image on amazon for reference, only to find out the pieces don’t go in the same places as in the picture, i then discovered some pieces don’t click into the places they are meant to and will fall out no matter how hard i push them in. as i looked at the product more i found some pieces had been shoved in out of place and has broken parts of the plastic box. the tube piece in the picture is shorter and fits in the box, whereas in the box i’ve been sent the tube it longer so they have bent it to fit the box. not happy at all. i would not recommended this product, certainly not for the price of it.

I do not recommend it, the material is weak and bends in your hands

It didn't work for me but I'm sure I might of had a faulty unit

Good kit and did exactly as advertised. Replaced valve stem seals on a mk4 golf 2.0L BEV.

Alles ist super

il n'y a pas le bon adaptateur pour aller se visser dans le puits de bougie d'une mini cooper R56, j'ai donc du mixer avec le tuyau d' un compressiometre qui lui.... avait du être bricolé également (même type de mauvais outil chinois) pour le même problème ! bref tous les grincheux qui postent des avis négatifs devraient relativiser, ça leur a évité de déculasser, et faut arrêter de croire qu'un outil à 50 balles est un outil professionnel. Ma mini ne fume plus j'ai pu changer les joints de soupape, et j'ai économisé au moins 2000 balles. ça valait bien le coup !

We had a 2014 Jeep Wrangler 3.6 liter Pentastar come in running bad and skipping. We found the engine had a broken intake valve spring. This tool was easy to use, and worked very well to compress the damaged valve spring and allow us to install the new one. There are no directions, so you kind of have to figure it out on your own, but it's not difficult. We ended up using the camshaft cap mounting holes to install the brackets. After that it was simple. I know they have a lot of problems with the valve train (rocker arms) on this engine, but this is the first one we had with a broken valve spring. I am very pleased with this purchase.

Why did you pick this product vs others?: This tool worked for a 01 honda civic. But you will only get 2 bolts to fit on locking this down to the head. But it works.
