Solutions to Common Cylinder Honing Problems

Cylinder bore quality plays a huge role in reducing friction and blowby for improved engine performance and durability. Better bore geometry also contributes to better sealing and more usable power.

Below are some solutions to the most common honing problems.

91743glazedjpg_00000045981PROBLEM: Hone is not cutting

• If stones are loading, you need to apply more honing oil to properly flush stones. Manufacturers such as Goodson recommend their a filtered honing oil.

• Make sure that your guide blocks are not too tight. Honing stones should contact the cylinder first. You should put the hone in the cylinder and then expand. The guide blocks should have about .010˝ to .030˝ clearance.

• Try narrowing your stones, this will put more pressure on the abrasive. Use an old file or dressing stone to narrow the face of the hone stone. Along the entire length of the stone, take approximately 1/3 off the leading edge. This produces more effective pressure on the stone without changing the pressure setting of the hone.

PROBLEM: Hone is chattering

• To eliminate chatter, try varying the stroke rate as you hone.

• Try some of the tips listed above for troubleshooting if the “hone is not cutting” usually any of those suggestions will also help overcome chatter.

PROBLEM: Stones and guides are wearing unevenly

• This is most commonly the result of light honing pressure. To remedy this problem, increase pressure and vary stroke rate momentarily.

PROBLEM: Taper in cylinders with limited access

• Taper will develop while honing a cylinder that doesn’t permit equal overstroking at both ends. There is a tendency for the hone to dwell at the open end of the cylinder and remove too much material. Dwelling at the web end is not a solution because it removes too much material from the center and causes a barrel-shaped cylinder.

• Manufacturers offer special honing stones that prevent taper in these cylinders. They have shorter stones that exert more pressure at the bottom and are specially designed for use in short or blind holes.

Jesel Certified Performance Rebuilds

Engine components are serious investments for any racer and maintaining that investment could be the difference between winning a championship and losing it.

Now that the race season is over, it’s a great time to freshen up your engine. Many shops are calling on their race customers to get a jump on that rebuild work before things get crazy again quickly in early 2023. One rebuild service folks with Jesel components might want to consider is taking advantage of Jesel’s CPR department to inspect, update and rebuild your Jesel rockers, lifters and followers.

Going the Extra Mile with Cylinder Head Porting

It’s not just the port work alone that creates spectacular cylinder head performance. The most critical areas of a cylinder head are those which pass the most air at the highest speed and for the longest duration. Your bowl area, the valve job, the throat diameter, and combustion chamber are all crucial parts. 

Tight Tolerances and Building Power

As you ascend Mt. Everest, you reach an area called the death zone. Once you climb high enough, the margin of error becomes perilously thin. That death zone also applies to engines. As the horsepower per cubic inch and rpm increase, the margin of error decreases. 

CNC Update: Features and Automation

Precision is key when it comes to automotive parts; the complex designs of connecting rods, pistons and rings, blocks, cylinder heads, and other parts require super tight tolerances that are getting more and more difficult to be met by hand or with other machining processes outside of CNC.

All Things Media Blasting

Engine building is a segment of the automotive industry that has always been ahead of the curve in media blasting, and no matter the engine shop, cleaning equipment is a common bond.
