Personally, I think it is mostly pointless.

Have yet to see an ISX fail because of dry-starts,. Hell, for that matter, even have some excessive wear. even so, a bit of gear lube at oil changes would prevent most of it any ways.

When you consider why most people have to do major repairs to an ISX, it is almost always the components that don't even have oil going through them.

Some could argue the whole over-head cam wear issues, but there again, Valve adjustments at proper intervals + keeping the oil CLEAN AND FREE OF WEAR METAL BUILDUP or other contaminants like excess soot + changing it before the additives start to separate (regular intervals and not extended oil changes) and I have yet to see a problem with one.

I have heard of companies who have spent tens of thousands on those pre-lube and other systems only to yank them off again because of problems in winter and maintenance issues on them where no benefit was seen whatsoever, considering lubricated parts are hardly ever the problem with engines these days to begin with if they are even half-way cared for properly.


I do however maintain that bypass oil filtration itself IS A GOOD THING to reduce soot and other contaminants, as long as it is not accompanied with extending oil drain intervals. This however does not require an electric pump, that can potentially wear and put wear metals or other contaminants into the engine to achieve.

On the rare occasion where you would actually have a dry-start situation, like months of sitting, or after an in-frame,.. an external pump works just fine.


Just my own thoughts, no one has to agree.
