W86552 2-Piece Valve Lapper Set for Vehicle Oil Systems Maintenance and Repair, Black

Works great. Still a huge pain with motor in the truck, but literally impossible to remove these lifter in my 350 sbc without the tool!

Works as intended, must have for DIY'er tool box.

Its well made and simple but really didn't work for my purposes. I didn't need it to access my lifters since I could pluck them out of their bores with a magnet. It works well for standard lifters but is useless for AFM spring lifters.

Suction paper could be better but it would be hard to design something that would be better. The issue is that as you move the tool the suction, since is not 100% perfectly balanced it tends to move and also since you are using your hands to move the tool as the user sometimes you might grab it differently and make the tool slip off the valves but overall a good value and it works.

Work as made to, does good finish work. I ended up using a variable speed 3/8 drill hooked to the valve stem on low to speed up the process with the heads solid on the work bench. Valve in place, drill chucked firm but not tight to valve stem tip, light pressure, no problems. Don't want to chuck it too tight, might mar the stem tip, not too much pull pressure and it did not slip ever for me. No marks on any of the valve stem tips. Ran it low, and kept eye on valve stem & head alignment. If your careful and gentile you can feel the valve head is grinding on seat correctly. Checked fit using the felt ink pen on valve and seat, used this tool to turn the valve for this step. Both valve seat and the valve head had the desired smooth shiny and correct bevel placement. This tool will do it all, but you will feel like a cave man starting a fire, and it takes time, lots of it for automobile valve work. Wouldn't be a problem for say a lawn mower, chain saw, or small engine. Worked for me

worked very well for all but 1 lifter on my SBC, otherwise it did work well for the price, I was able to extract 15/16 stuck lifters, would be 5 stars if it could have got the last one. I wish there was a smaller diameter end so you can get a better grip on more seized /smaller lifters

Worked well. I used it on a recent head kit replacement on a Kohler CH18.

Well built much needed and appreciated

Perfecto funcionan muy bien gracias

Going to give it 5 stars, but, I did have trouble. seems well built. I had trouble keeping the suction cup stuck to the valve. tried cleaning cup and valve many times, used water and spit to try to improve suction cup stick. I cleaned the valve and could never get more that 2 or 3 series of turns before it popped off. Could be operator inexperience (me). I've read that many people have difficulty with these types of lappers. in the end, it did the job, but cause a few cursing streaks.requires patience.

Just finished using the puller and it worked great

Very quick shipping. Looks to be just what I need

De las 4 gomas, solo una está suave las otras 3 estás muy duras y creo que no va a funcionar bien para mantener la válvula pegada a la ventosa.
