Diesel in Oil, Slobber Tube White Smoke

[Jim Blackwood]

Anyone ever had a problem with micro-erosion of their Series 60's liners by the coolant? Brother Andy had that issue at a fairly early stage with his Peterbilt, I seem to remember him saying it was due to coolant contamination and electrolytic discharges like microscopic lightning bolts striking the liners.

Weird, huh? Just curious, not that it helps any.

That is called cavitation. Google it.
From the description, no mater how you cut it, it needs torn down and repaired. 60 series don't " get better" by running it hard. We're not talking a two stroke here.

Yeah that's long since done, just something I remembered. He might have even referred to it as cavitation but that's something usually associated with impellers. Not sure how that works with liners.

Thanks for the link. That was the bugaboo alright. My guess is he (and probably lots of other owner/operators) overlooked the additive requirement every 250 hours.

Wonder what that says for us?

Coolant test strips should be standard issue for any bus owner.

Coolant "filter" is often ignored or removed by the last, lowest tier, Penny pinching commercial operator...

It looks like a filter, and is often called a filter, but it doesn't "filter". It has sacrificial layers inside it that feed the SCA additive package into the coolant over time.

In the old books, you might read about a "Perry" coolant filter.

Keep this up to date with your operating hours/mileage, along with test strip monitoring, and all will be fine.

Proper chemistry inside your heavy diesel engine matters a lot!

Happy coaching!
