So many comments from people that never did enough engines. Cast rings are very forgiving. My grandma could hone a cylinder and it would turn out just fine with cast rings. When you build a bomber race cheap claimer engine, you want everything loose. Now if you are building a high mileage engine you want 250,000 miles out of it, it's put together completely different.

This is where all the power is in the engine. We are talking hundreds of horsepower! Very few people understand how to get this easy horsepower. Needless to say, keep your cylinder walls straight. The easiest way is to take a piston turn it upside down in a bore with the rod and measure the piston to wall clearance at the top middle and bottom with a long truck Diesel feeler gauge. Another big factor is how course or smooth the stones are and the amount of clearance that’s best for your application. This is one of the best kept secrets in engine building.

Dont listen to the nay sayers. Some of these people forget that the entire point is to do this on a budget, not perfection. It wont be perfect but the whole point of honing is to create a rough surface so the rings and the walls grind themselves perfect in due time and use. Good work for 20 bucks.

Everything you said is total BS.

So if you had a block that still had the original honing marks would it not need to be done again ?

Hi sir after the hone you can use the same piston or you will be installing the big one ?

Hi just want to know how the build went. I've got a diesel that I had changed rings twice. It won't bed. Taking it apart again to do honing, just want to know how it worked for you.

That's like we use to do it, It smoked like a SOB but we could buy the oil by the case for about 40 cents a bottle, they said the engine did better using a little oil, what you think about being better using a little oil

it works? how long does the car drive after such treatment? then the nominal rings and pistons are fitted?

Great vid. Do i need to used stock size of piston and rings or go one size up after honing?

@ Rholdan Yabut- It depends on the pistons in the motor. Mine were previously oversized .030. So I had to go with rings that would fit that piston. I do not believe that honing the cylinders would require a larger ring.

@@rholds1973 you need to mic the cylinders to check the tolerance. If you are already close to or over factory spec, it will need to be bored.

Bro.... rule number one when honing... ALWAYS USE A LUBRICANT!! That’s with any form of machining

@ronmckean2909

In the shop, when turning or milling cast iron, it is self lubricating. That is what I have been taught. Thats machining. This is using stones. Stones are not machining. (Not counting grinders)

Is it worn out and not fix piston?

DONT STOP IT WHILE ITS STILL IN THE CYLINDER GOOD GOD

What hone u useing

Is that standard bore?

Going way too fast to get a good crosshatch and stopping it in the bore leaves vertical lines on the walls when you pull it out. How'd the engine turn out?

This guy is doing it wrong. 20 -45 seconds per cyl usually and the goal is to get a nice cross hatch pattern while removing the glaze . Also I don't recommend wd-40. Just my .02cents

351M/400 good motor to hone. Crank mains blow out way before the bore goes bad.

What grit is that hone

Set diesels up dry in the cylinders, put it together fast and crank it up. The rings will set in less than a minute.

once your're done how would you know what size pistons and rings to use? Like .020 or .030? Thank you

@ Marcus- Honing your cylinders does not remove nearly enough material to go up in ring size. You would have to get your cylinders reamed by a machine shop to require an upsize in rings. I would stick with the same sized ring that was in it previously. I hope this helps.

you need a cross hatch pattern best to practice on old motor to figure out speed

That home is not straight it's moving all around it's wobbling what's your own video did this motor turn out okay?

You need to run the drill clockwise and then counter clockwise to get a good crosshatch, also a few seconds each way usually does the trick, just trying to take the mirror shine out of cylinder.

Don’t see how you got a 45 deg cross hatch with that drill speed and action 🤷‍♂️. I lol keep searching for someone that does it right 😎

That is a ford 351m/400 block

Honing cylinders like that will leave cylinder bell mouthed

DIY guys can call this whatever they want. No engine machinist is going to call this a hone job. This is nothing more than deglazing. A hone job removes material and straightens bores. This does not.

Have this professionally done with torque plates. You may get a nice looking cly.but it doesnt let you know what the bore taper is!!

I would just leave it into the engine shop to someone a bit more skilled, I think this is too random, not checking with internal measuring device, might affect compression

Pay close attention. This is the wrong way to do it. Honing a cylinder requires critical measurements before and after. He doesn't measure at all.

Ball hone is the best.

@bryangillis5183

Ball hone isn’t best at all. Ball hone will hide defects in the cylinder wall that a flat stone will reveal. The only time to use a ball hone is when you know 100% sure after measuring your cylinder walls are straight and don’t have waves in them or big gouges. A flat stone hone is the best tool for home use although his technique is wrong. The up and down motion should be faster as well as the rpm. Watch any hone machine in a machine shop and you’ll see the difference.
