Review on Mr Gasket 5189 Engine Cleaning by Arturo Reyes

The brushes did the job for the price in cleaning the sides of my small block Chevy. I used oil galleys for all bolt holes and cylinder blocks. The only thing it's missing are piston bore brushes, but you can get a full set from Mr. Gasket 5192 if you need more brush sizes. The three long brushes can bend along the shaft if you just drive the brushes into long galleys. Take your time and support the waves as you enter the block to reduce flex. If they are bent, you can straighten them and use them again.
