Cylinder Honing
- Thread starter cal1780

Well,
I have no idea if a good rebuilder would do it this way. But I took a wire wheel & my drill & went at it. My cylinders were all quite clean & had the original honing marks still mostly there. The top of the cylinders were obviously dirtier & had the cooked on carbon ring. The brushing cleaned them up very well & left very light, consistent, horizontal lines similar to the original honing marks. Worked great. Runs great.
Good luck,

when you have you`r cylinders honed you use the stock pistons don`t you ?
Boring is cutting a cylinder to a particular size. Honing is the final step to dress up a cylinder bore to get it to the right size and put the proper finish on it. Think of it as sanding the cylinder smooth.
If the cylinder wall is within allowable specs, you can use a hone to add a crosshatch to deglaze and help ring seating on a re-ring, but you don't want to take off too much.
I would not attempt to hone an engine in the car, though. When you are fininshed you need to be able to clean it very thoroughly. Honing leaves a very fine abrasive grit behind that must be removed. Doing it in the car wouldn't afford you that opportunity and all that crud will be left behind to eat away at your crank, bearings, cam, and everything else. It would be like dumping sand in the engine.

You re-use whatever pistons you have on a simple re-ring and hone job. I have always honed the cylinders on a ring job, but there is some evidence that it isn't necessary and may even be detrimental. When doing an in-frame ring job I just cover the crankshaft with shop towels and hone away, then clean it all up as best you can. I learned the hard way not to put chrome rings in when not doing a re-bore
A Datsun pickup that I did that to took over 100,000 miles to seat the rings. It didn't burn oil before, but it sure did afterwards. Joe
