Over 10,000 Hours on an Original Perkins

Diesels that are well looked after can do a hell of a lot of hours.

Oil condition will tell you a lot if there are problems. Otherwise clean oil, clean fuel and keep the levels up.

[QUOTE=lifeofreilly57;1601767]. Seeing chrome specs in the oil filter folds usually means there's a crank rebuild in your future.

I don't think Perkins chrome plated their crank journals. So if you see chrome flakes in the filter it might be a piston ring coating.
Bronze is usually a bushing. Steel parts are gears or perhaps a lifter or valve train. Iron parts are often a cam lobe. Aluminum (piston) and bearing material often look the same. You can tell the difference with a soldering iron tip. The tin coating on the bearing will melt. Copper is a worn bearing. What you see most often are rust flakes and bits of carbon. There is sometimes what we call "mung" which is kind of a mud from the cylinder walls and everything else in there.

The Perkins 6.354 I have seen on stationary generators are commonly scheduled for a top end job at 20,000 hours and a major overhaul at 40,000 hours.

Those are the 5 ring versions which are relatively rare in boats. I was fortunate enough to have one and wish I had it still. IMHO quite possibly the best diesel ever built.

That is pretty amazing. 10,000 hours is 460 days non-stop.

In a truck... running 60 MPH, 18 hours a day, 10k hours would be 600,000 miles.

Good engine.

A Million miles is not all that uncommon on an OTR truck, and I think average speed is closer to 30.
That is closer to 33,000 hours?

I'm sure mine would go another 5000 hours but it leaks oil like a seive, I have a tray under the engine with oil absorbent pads and have to change them every 8 hours. I'll be pulling it next winter to fix that and will rebuild it at the same time, not because it needs it, but it would be stupid not to while it's out of the boat.
Fortunately their not that expensive to rebuild if you do the work yourself.
