Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / May 2006Repair Damage from Cavitation
I've got pin holes in the cylinder wall of my 7.3L diesel. My research has turned up many ways to prevent this, but I cannot find many methods to repair. So far all I've found is that I could have the cylinders sleeved, but this needs to be done with someone who has experience with this process. Are there any other satisfactory fixes?

Either sleeving or boring would be the choices I can think of. But boring may not be an option depending on the severity of the pitting.

The pin holes are from the water jacket -into- the cylinder. >>I've got pin holes in the cylinder wall of my 7.3L diesel.

That means that the coolant passages have ALREADY eaten through into the cylinders- boring will only find air!

Otherwise, it's new block time. > I've got pin holes in the cylinder wall of my 7.3L diesel.

Once the cylinder walls are holed, the block is junk unless you sleeve it. Period. Next time use a coolant specified for heavy diesels. They have nitrite additives to prevent cavitation damage. |
