Do I need to bore and hone a new cylinder?
Depending on the application, instructions for your new pistons will specify that the cylinder needs a bore and hone, bore/replace, or deglaze/hone. More often than not, you will need to hone your cylinder when replacing the piston rings.
Why do you need to honing a new piston?
That is because honing creates small crosshatches in the surface of the cylinder, to allow the wall of the component to retain oil and provide lubrication for the piston ring. Even though the instructions for the new piston may specify that honing your cylinder is required, you can also manually check and see if your cylinder requires it.
Does cylinder honing make a difference?
Proper cylinder honing can make a noticeable difference in engine performance and durability. Cylinder honing is just one element in high-performance engine preparation that is often taken for granted, yet it can be an effective means of not only helping to maintain proper oil control, but increasing horsepower, as well.
Should I hone my cylinder when replacing piston rings?
- Extrude Hone AFM Should I hone my cylinder when replacing my piston rings? To make a long answer short, you should probably hone your cylinder when replacing piston rings. But, the full answer depends on a few things, including the type of piston you order and the age of your cylinder.

Why use a torque plate?
A torque plate, when used with the proper head gasket and fasteners, simulates the loads placed on the block when the cylinder head is installed, and therefore, helps achieve rounder and truer cylinder bores during the honing process , keeping bore distortion to a minimum. Most high-performance engine shops carry torque plates for most popular engines.
What brands of cylinder honing are available?
A complete list of cylinder honing procedures, recommendations and tech tips are available from manufacturers including Hastings, Total Seal, and Sunnen .
How to check cross hatch angle?
To check cross-hatch angle with the special business card, begin by removing the translucent backing off of the card. Follow by pressing it into the curvature of the cylinder and aligning the top edge of the card with the deck surface. Proceed by then reading the card by doubling the amount that matches the cross-hatch. For example, if it reads 20 degrees, the true angle is 40 degrees.
How much horsepower does a cylinder honing engine have?
In high-end racing engines, the difference between proper and improper cylinder honing operations can equate to as much as 30 horsepower, according to experts.
How to inspect cylinder bores?
Cylinder bores may be inspected using a dial bore gauge with a torque plate in place. After machining operations are completed, it is crucial that the engine be thoroughly scrubbed with soap and water. Nothing is more detrimental to an engine than dirt and debris.
What is cylinder bore finish?
When proper honing has been performed, the cylinder bore finish results in an engine that offers both superior ring seal and extended ring life. It is often a delicate balance of having sufficient surface area to allow the piston rings to seal, but not so great that oil retention and ring lubrication are compromised.
What is cylinder honing?

What is a good machine shop?
A good machine shop will be able to tell you what is best for your specific block, what costs to expect, and which way to go with parts, etc. Working with your machine shop will produce the best results. Also, when they do the honing, ensure they use a torque plate during the final honing process. This ensures the cylinders will be right when you bolt the heads back onto the block.
What is the meaning of "back up"?
Making statements based on opinion; back them up with references or personal experience.
What to do if you break through a 79?
If it was a '79, I'd say take the chance - bore it, and if you break through into the water jacket, get another block & rebuild THAT. If it was a '69, I'd even urge you more strongly to do that. Not for a '99, though.
Do you need to bore a block to replace pistons?
If you are having to replace the pistons anyway, get the block bored (as long as it's an iron block, which is an assumption on my part). Not only will this give you more displacement (which will equate to more torque for your truck), but will ensure you have perfectly round cylinders as well, as well as symmetrical top to bottom. It will also save you in the long run if "just honing" is not going to work.
Can you bore a block?
I'd recommend that you bore, but I 'm not sure that block CAN be bored. Some can't - the water jacket is too close. Sometimes, even, those that SAY they can actually cannot because of a casting inclusion or bubble. If boring breaks into one, the block is suddenly complete junk.
What is the purpose of compression rings?
1)The compression rings provide sealing above the piston and prevent the gas leakage from the combustion side. The primary function of these rings is to seal the combustion gases and transfer heat fr
What happens when piston rings are worn?
Now the piston rings being worn or cracked will allow the high pressure gasses during combus
What causes a piston to blow by?
This makes higher than normal pressure inside the engine and it tends to want to escape. This phenomenon is called blow by. Blow by can cause gaskets to fail causing oil to bepushed out and even the oil check dip stick can get shot out of it's tube. Conducting a static compression check will isolate the bad cylinder. Blow by is serious and you should have a mechanic determine the cause.
Can worn piston rings cause over heating?
In my experience “Bad” (worn) piston rings or worn bores do not cause over heating; it results in low compression and/or burning oil. Burning oil causes blue exhaust smoke when you increase revs, check if this is what you have got as it will confirm bad rings/bore but will not get you any further with your overheating.
Why does my engine overheat?
Engine overheating can be caused by a too lean fuel mixture or a cooling system fault. Cooling system faults can include low coolant level, which can also point to head gasket failure if there are no obvious leaks. A blocked radiator, blocked engine water passages or failed water
Why does my car smoke at start up?
If you have bad valve seals you will see black smoke at initial start up after the car has sat all night. If the valve stem seals are bad they allow oil to pass and it sits on top of the valve. When your start the engine this oil gets sucked into the combustion chamber where it mixes with the air fuel mixture and gets burned along with it. This gives you the smoke in the morning. Once the oil gets burned off the valves you really can't tell they are leaking oil. The smoke in the morning is the giveaway.
Can you drive a car with bad piston rings?
You can drive your vehicle with bad piston rings for certain kilometres but you have to get it fixed as soon as possible or you will damage your engine.
