Ford Mustang Short-Block Engine Rebuild - Recession Special Part 1
|
If you look in the cylinders, you'll probably see remnants of the old hone that look like scrapes. These are called crosshatch marks. You'll want to duplicate them and the angle they cross (about 45 degrees) with the new hone. To do this, you'll need to vary both the drill speed and the speed at which you plunge the tool in and out. A slower drill speed will work quicker, and you won't have to move the drill in and out as fast. Use some 30-weight motor oil on the cylinder surfaces during the process. It should take less than five minutes per cylinder to remove the glaze or shininess of each cylinder wall and return it to a slightly rough surface (with the proper crosshatch). If you find you need to spend more time working the hone to take out the imperfections, you might need to have the cylinders bored out by a machine shop. If the engine was in good shape to begin with, however, this shouldn't be necessary. View Related Article
