Has anyone seen cylinder bore pinholes in the Brazilian Ford blocks? Have the 6.6 in a 1992 Ford bus, Allison auto. Just wondering if they were prone to cavitation erosion too, has 120,000 miles on it, last used as a church bus. Thanks in advance..
 
You can buy a kit to test and treat the coolant to prevent problems at your local auto parts store.
 
JD markets an additive and you need to follow the directions. Seems it's just as bad to over do it as to under do it.

OTR trucks use a spin on filter that is plumbed in parallel off the water pump with a 3/4" hose....partial flow but over time gets the job done. Not that expensive, kind of like getting a filter for your diesel tank output hose......filter and filter base, some 3/4" hose.

Pick one and quit wondering. Sleep well at night.
