Brush Research GBD40024 FLEX-HONE, 4 (101mm) Diameter, 240 Grit, Silicon Carbide Abrasive (Pack of 1)

I have a 2005 Honda CRV that was burning one quart of oil per tank of gas. YES you did read that correctly. Car was abused before I got it, but now I have to fix it. Pulled the engine apart and found scoring on the #4 cylinder wall and a damaged piston. Replaced all 4 pistons, rings, and rod bearings. Took this hone to all the cylinder walls with a little extra in #4. All the bores came out factory perfect, except #4 which I would give a 8 out of 10. You could still see some vertical lines but it was 95% better than before. Hondas stance is do not hone, just install rings, and if you can catch a scratch with your fingernail, the block needs replacement. Well I wasnt replacing my block, so this was the next best thing. Put it all back together and the engine runs perfect. Car does not burn a drop of oil and the oil is still golden. It would be black from blowby within 500 miles before. Very pleased! and highly recommended.

Product did job as advertised worked really well

These ball hones are just right for a quick pass or two without removing too much material. Take care using them and it will last longer. Dont run them past the bottom of the bore or allow them to pop out the top during use. Check your speed and a nice cross hatch pattern is easy to achieve. I used the companion honing oil, pricey but easy clean up make it worth the money.

This was so easy and idiot-proof. Absolutely fantastic results!

This hone did a nice job on a pair of Harley Twincam cylinders. New rings seated in nicely and had a good seal.

Worked great!

We needed this tool for rebuilding motors. Worked great.

Smooth

Worked as expected

Bought this to rebuild a LS 5.3L. 5 seconds in each hole on low speed. Perfection!
