Seriously, the truck started with difficulty and ran. It knocked and made unhappy noises. Maybe has some misfires. It smoked gray at all speeds. My truck would would start after sitting overnight and die immediately when I tried to accelerate. I replaced the lift pump which made it better for 6...

I tried to reseal an injection pump and this was my result. Should've just done the throttle shaft seal.

Take the caliper off and rotate it so the bleeder is on the bottom before flushing. Rock Auto has caliper seals. It's really inexpensive to open the calipers and clean them out properly. They are tricky to reassemble. Mine had a waterline at the middle of the piston. The piston and bore are...

You don't need a cup reamer unless you see carbon in the injector bore. A rag and a screwdriver is usually sufficient.

No need to wire brush. Wipe it down with phosphoric acid. Some paints will tolerate some flash rusting. Hydroblasting is gaining popularity for industrial applications for a variety of reasons. There are corrosion inhibitors that can be added to the water to prevent flash rusting but most paint...

I wonder if anyone has considered using helicopter or turboprop transmission oils in their gear hubs. Turbine transmissions operate at high speed and load continuously. Recently I was presented with some large bearings that were overheating. Previous operators decided to use high temperature...

Watch the volt meter on the dash. It should dip during the glow plug cycle. That is a quick way to determine glow plugs are working. Look for white smoke from exhaust. No smoke means no fuel. The throttle shaft seal on the injection pumps fail and that lets the pump drain when the truck sits...

The voltage to the glow plugs should actually be 10.5 volts. Can you give us a better description of not starting? Is the engine turning on the starter? Are you getting any vapor out of the exhaust? You have clearly made an assumption but not told us anything about what you know.

When you buy the test kits you have to buy a special fluid for diesel engines. They don't have less CO2 in their combustion products than gas engines. With that said, the only time I have tried to use a kit was on a Cat 3512 that was blowing bubbles. The test never indicated anything. We used...

I think they use grease for damping which gets hard over time. I don't know what viscosity.or consistency grease should be used but if you never want to do it again Krytox GPL 200 series should have what you need.

That's exactly what my 6.2 was doing. It would push coolant into the reservoir when running but would hold pressure for months when the engine wasn't running. This kept it from pulling coolant from the reservoir. It ran this way for quite some time but gradually got worse. Disassembly revealed...

Pshhh, I've done 850 miles in one day in my M1008. 🤪

That means your Gen 1 isn't working.

There are inorganic aluminum-zinc coatings that are far superior to plated fasteners and perform almost as well as stainless with less seizing issues.. Dacromet is a common trade name. https://www.nofmetalcoatings.com/ I am a little embarrassed to share the link to their website. It has...

The injection pump will cause over fueling and black smoke if it has been turned up or built to a higher output spec which is quite possible to have been done during a rebuild.

On the civvy engines 88.5 and earlier had long bodies and later had short. Your application likely has shorts. You can tweek the injector lines to fit shorts if you have to.

Some engine manufacturers want sodium nitrite in the coolant to prevent liner cavitation. These are the HOAT coolants. If you have a Caterpillar dealership nearby buy their ELC coolant. It is a HOAT. You will not find an IAT coolant at an automotive parts store. If for some reason you want to...

The Nox-Rust product is a newer technology based on gelled calcium sulfonate. It resembles a wax or bitumen coating but it is not. The gelled calcium sulfonate coatings are not oily so they don't mess with painted surfaces but they also don't soak into crevices like the Fluid Film products do.

The epoxy zinc on blasted metal is by far the best route but if you're patching up you're existing coatings under your truck there is a product from Daubert called Nox-Rust 121B. This is the "wax" coating used by GM on some of their frames. It's suitable for marginally prepared surfaces. It's...

We do oil samples in our fleet because we can show them to auditors. The like to see them but they don't provide much value to us as operators. Coolant samples are much more preventative but it's very hard to convince the oil is the most important fluid establishment that this is the case. Your...
