How long does Nikasil last?
A cylinder can last indefinitely if cared for properly. >> 2.
How thick can Nikasil plating be?
Coating Thickness of Nikasil®
In practical use the cylinder walls or sleeves are electroplated with a layer of Nikasil®, typically between 80 and 180 µm thick.
What is a piston sleeve?
It is a cylinder that is fitted to the engine block to form the cylinder, and is one critical function part that forms the engine interior. In Japan they are usually called Cylinder Liners, but some countries (companies) call them Cylinder Sleeves.
How do you identify a Nikasil cylinder?
If all else fails you can use a magnet to try to see what type of material you have the Casilla does have magnetic properties so a magnet will stick to it.
What is the Nikasil problem?
Over time the sulfuric acid will start to corrode the Nikasil lining causing the cylinders walls to become scored, sometimes through the coating and into the underlying engine block. This in turn causes the cylinders to lose compression and ultimately leads to premature engine failure.
Should I hone a Nikasil cylinder?
If the Nikasil plating is chipped, nicked, cut-through, has worn spots or is showing signs of wear, do not use Flex-Hone® tools. Instead, strip and re-plate the coating, or replace the cylinder altogether. Again, because Nikasil platings are very thin and very hard, honing will expose any existing damage.

When did Jaguar stop using Nikasil?

Is Nikasil a chrome?
Nikasil is oleophilic, reduces friction and is harder then a chrome plating. The chrome plating is also prone to chipping.
Should you hone Nikasil cylinder?
How is Nikasil applied?
Nikasil plating was applied to the aluminum alloy casings using an electrolytic deposition (electroplating) process in which silicon carbide (SiC) particles dispersed in a nickel (Ni) matrix were applied, providing the wear surface.
What grit should I use to hone cylinders?
Hones with 180 to 240 grits are good choices for general deglazing where the cylinder is not going to be bored or honed. A 320 grit, and even sometimes as fine as 400 grit are often used in high performance applications with high performance ring sets.
Can you hone a Nikasil cylinder?
Why are sleeved cylinders used?
Sleeves 101
The primary reason for sleeving an engine to either repair a cylinder bore or protect it from damage in the first place. Sleeves can also be used to restore a particular bore size if a cylinder has to be “bored out” to repair a cracked or otherwise damaged engine.
Can you bore a sleeve cylinder?
L.A.SLEEVE manufactures our cylinder sleeves from a centrifugally spun cast iron alloy of carbon-chrome and molybdenum. The MOLY 2000 iron alloy material features many of the same alloys that are used in todays plated aluminum cylinders. Unlike plated aluminum bores, sleeves are boreable.
When should you sleeve a block?
