9 Worst Things You Can Do to a Diesel Engine

I'm assuming the BX fuel tanks are plastic? Could be shaped with a slope or cone for any heavy sediment to collect in with a valved drain hole at the lowest point. If the fuel out line is above that point. Minimal chance for needing to purge air out of the system if sediment is flushed with at least a half full tank.

Guessing alga are either clinging to the tank of floating? If so, a clean out hatch would still be a nice standard feature. I would pay an extra ~$100 for the feature. Another sales point for Kubota.

I wounder what number EGR is?

Missing the #1 rule, don't loan it to the neighbor / friend / brother in-law... and so on!

I learned that the hard way, and it also applies to the lending of hand or power tools, even hammers.

I have a new to me 20 year old changfa single cylinder generator. I also have a turbo diesel monster and an old B7100 and a diesel 6x4. I never have diesel problems.

Most people don't understand the dynamics of a diesel engines - they are thinking carburetors - if they even understand those often times. The biggest is pure, filtered fuel. No crap. No water/moisture.

The injectors - you can't see the squirt holes they are so small. But when the fuel comes through those holes at the critical moment it makes so much efficient power (torque) it is amazing. Look at the diesel / gasoline ratios. Diesels are not hot rods. Nor can a hot rod pull a load for very long. One for one thing and another for something else. I've gone a quarter mile in ten seconds. Don't tell me about diesel.

People don't understand the machine for the job. Horsepower for weight and the footprint to carry it. In the ground conditions, duh?

The wife bought me a LBH that I can break the roots of a 100' pine and push it over in 15 minutes. I don't use it too much- mostly to lift things I can't lift or warm it up and exercise pins. We get older and appreciate a machine more every day.

So do you pry bar.

I've heard of 'hot stacking' but never experienced it in all my years. Hot stacking is running a diesel at high idle but not under load for an extended period. Actually I think low idle for long periods at no load would be worse. But why would anyone do that anyway?

A truck idling at a stop overnight is a perfect example. I don't know. I've never used a diesel like that.

The worst thing you can do is neglect. From no maintenance to never running and letting moisture build up inside.

Running, thinking minimum RPM will induce the least wear is pretty wrong, excessive loading at low rpm is tough on rods and pistons. Just like too low of an idle will quickly kill an engine. Most engines are 'happiest' at the Hp/Torque curve intersection. Most efficient too as pumping losses are minimal.

Used to be with a gasoline engine, starting and stopping was bad due to excess fuel washing the oil film away from the cylinder. Not the case with modern FI engines.

The only engines I have ever had issues with are modern auto engines that fail over time and not from use or abuse. The simpler (less electronics) the more durable/long lasting.

I wounder what number EGR is?

Yeah. EGR is the worst thing that ever happened to diesel engines. With modern diesels it's suggested to remove the intake every 30 to 50k miles or so and use a walnut shell blasting process to get rid of the carbon build up.

Here's the intake in a 3.0L EcoDiesel out of a Jeep that was featured on Dave's Auto Center YouTube channel recently.

I want to add that tech to my BX23S, plz.

I suggest running a flexible pipe from the exhaust outlet to a T fitting on the intake. That way you can keep all of the carbon in constant circulation, not to mention have a zero emissions tractor.

As part of my plan to mitigate fouling in the intake of the F-450 I ordered a CCV recirculating kit from SPE Motorsport (friend recommended) that will have to suffice until the truck's warranty expires and then I'll get medieval on the beast. The kit reduces the amount of oil that heads from the crankcase and back into the engine via the intake. Dry carbon has less of a tendency to gum up the intake, so that'll have to do for now.
