There’s an issue that comes with the running of backup engines, and not only is it avoidable, but it’s also often mistaken for something else.

As a result, you end up with misdirected investigations, with the potential of increased cost and downtime.

So what’s the issue?

Wet stacking.

“Wet stacking” is a widespread problem that generally occurs in diesel engines operating at low load or with no load for extended periods.

Evidence of wet stacking is often mistaken for an oil leak, but as you can see from the picture the liquid is jet black rather than oil like.
