Anytime Mike.

I am always amazed by the things that can be done to a diesel engine. From the old 2 cylinder John Deere tractors with bucket sized pistons to the screaming 2 cycle Detroit's to the tiny little 799cc 3 cylinder turbo diesel in the smart. I was in a shop once that was making a set of head bolts for a 4 cylinder Fiat diesel from an ocean going freighter. Each bolt was 9" in diameter and 33' long. I didn't get to see the pistons but they must have been impressive.

Gas vs. Diesel

I posted this in another thread. I've been dealing with Vander Haag's for new used and reman truck parts. It's interesting to look at their used diesels. "Only 383,000 miles". You won't see that on a 454.

I had to drain stale gasoline out of the lawnmower today. Nothing stinks like stale gas. Hard to wash off too.

Had a custom ordered 1975 5 cylinder Mercedes sedan. The engine ran well and was an excellent driver. Lovely red leather interior in a white car. Wish I still had it.

About that time Mercedes was looking for the highest mileage one owner car in America. A chap in the Northwest had a significant commute of over several hundred miles each way and the four cylinder normally aspirated 240D had a documented over one million miles on the vehicle. Just routine maintenance..........

Makes me think of the late 1930s built Douglas DC3 aircraft still flying today with over 50,000 flight hours. Good maintenance has kept this birds in the air all these years.

As a person who has ridden B.C Ferries many, many, too many times though the tiny stairways and been on a few RN vessels, I'm having a bit of difficulty try to fathom how they get the bolts into the engine compartment and further more; what kind of bad a$$ torque wrench would you need to torque those bad boys down.

Also trying to remember where the Millbay ferry went to, Swartz bay or an island? Most of my runs were to and fro from Saltspring Island. Beautiful area to explore.

Cheers

So you are saying that people routinely get 1 million miles out of 454s? Most I've seen, especially in heavier applications, don't make 100k.

Not routine, and this was probably a 350. But, I'm not that far from 100k, and the 454 seems to be pretty stable. I do change the oil a lot and keep a close eye on the engine temp when we are in the mountains.

It's actually called the Brentwood - Mill Bay Ferry and goes from basically Central Saanich west across the bay to just south of Mill Bay and north of the Malahat Pass. My buddy, the guy with the green Speedster lives in Saanich north of Victoria and it's a pleasant way to go north toward Duncan without going over the pass. We have driven the Malahat in the old Model T's and it's fun but it isn't very fast if you know what I mean.

When I worked at L.A. Water & Power about the largest bolts we dealt with were 5" dia. and 6 or 7 feet long. They had a hole bored down the center. We had long mics to measure the length, then insert a "bolt heater" to lengthen the bolt, take up the nut, let it cool and measure again. Torque was measured in "bolt stretch" which is actually the most accurate method.
To get the big stuff in and out of the ferries and ships they use a cutting torch, cut a big hole and weld it back up. It makes access easy.

Don't get me wrong! I'm not trashing the 454. I just got rid of a 98 Ford Explorer with a 5.0L (302) that was still running strong at 190k. It was very well cared for with religious oil changes at 5k with Mobil 1. I had a Toyota Cellica (22RE) that I gave to a friend at 180k. He's still driving it at 250k but its ready for the bone yard.

We have a bunch of U-pull-it "recycle" yards in Colorado. I use them for a source of parts for for vehicles I've restored and upgraded to modern drive trains. 150 to 180k seems to be the magic number where vehicles without obvious demise face the crusher.

My point being that they sell these used commercially operated diesels at half a million miles and consider them low mileage.

That said, you can abuse and burn up a diesel just as quick as a gas engine.

On the big truck engines it's' not unusual to get a million miles, I have 1.4 million on my E model cat, head never been off and original turbo, still doing good....my 7.3 ford with 189,000 the head gasket started leaking, fuel pump was also leaking and I sold it as is, I sure like my 6.7 dodge with 90,000 miles now......

Original turbo?? That has been another thing that I was worried about. I cannot believe something with that kind of tolerance could live that long. That's amazing. I had a discussion with a guy who was a truck driver for part of his life. He talked about how turbos decrease the life of an engine due to the pressures exerted. I believe in turbos, but I was under the impression (from this one person only) that a diesel would have a longer life without the one. But a million miles later, I suppose that was not educated information!

Seems like comments in many directions, I'll add one from last Thursday.

30' S/O 2005 Dodge Ram 2500 5.9L Cummins 6 speed.

Pulled I-77 NC into VA up to Fancy Gap. 7 miles 7% grade.

5th gear pull, engine added about 8-10 degrees on coolant temp. I have a digital Gage. Crested hill and down went engine temp.

Manual transmission, not racing, did its job admirably. Even accelerated a bit to pass and clear the lane.

Works for me.

Unfortunately, those selling diesel trucks with turbo chargers fail to mention proper startup and shut down procedures.

Start engine with foot off the throttle and do not rev the engine until full oil pressure is present. Give it a minute or so to get some warm oil in the bearings. Goosing the throttle at startup can score bearings as these turbos turn at close to 100,000 rpm (and the smaller ones we made could turn over 200,000 rpm) and need oil.

On shutdown, let the EGT drop to around 370 degrees or idle for a couple of minutes to get the temperature down on the exhaust system. If the engine is shutoff while still very hot (pulling into a fuel station after a hill, for example), the oil stops flowing with the turbo is still rotating at a high rpm which is bad for bearings and then the heat soak cooks the oil onto the turbine shaft and bearings (called coking).

With the newer variable vane turbochargers, proper starting and shutdown become more important as there are many more moving parts inside the unit.

The Insight Edge gage system I installed in our truck has an automatic shutdown feature that allows me to turn of the ignition switch, get out and lock the door and walk away with the engine running. It will turn off when the EGT has dropped to the temperature I set.
