Diesel

Hello, the only repair that can be made is to drain the fuel tank, flush the fuel lines, flush the fuel rail, and replace the fuel filter. The fuel tank once drained, can be removed and then the fuel pump...

Gasoline engines cannot run on diesel because it is very hard to get it to burn from the ignition; you need very high heat and pressure to get diesel to combust. For example, if you were to throw a match...

Check the battery in the car. The battery may not have the amount of charge that is needed to start the diesel engine. A diesel engine requires more battery power to start it as the compression is higher than a...

Hi and thanks for contacting Your Mechanic. The engine will burn the ultra-low, Low, and High sulfur content diesel at any time. The thing about the High sulfur diesel is that the lubricity of the fuel drops making the engine...

Hi there. Check the fuel filter and the fuel water separator for if they are old and need changed. Check the fuel water separator for a valve on the bottom and if there is a valve, if you can open...

Hi there. If your MB panel van is diesel, it's possible that the change in diesel fuel (https://www.yourmechanic.com/article/how-does-a-diesel-engine-work-by-jason-unrau) (summer to winter blend) along with a clogged fuel filter (https://www.yourmechanic.com/services/fuel-filter-replacement) or fuel injectors (https://www.yourmechanic.com/services/fuel-injector-replacement) might be causing the stumbling issue you're...

Hi. It depends if the knock goes away after the engine warms up. If it does, then yes, this is contributing to the knock. What is happening is that the fuel and chamber is not hot enough for combustion and...

Hi there. The air intake on today's modern cars are finely tuned pieces of equipment - especially on a diesel engine. If air flow is blocked or reduced in any way, it can cause the engine to have troubles maintaining...

A lot of times when the fuel tank is run completely empty trash will accumulate at the bottom of the tank in the fuel lines, which will make you car to be hard to start. Use a can of Seafoam...

In order for a catalytic converter to function without overheating (and melting and clogging) unburnt hydrocarbons in the exhaust stream must be kept below a relatively low "threshold". Normally, the amount of these unburnt hydrocarbons, which represent wasted potential energy...

Yes, this can happen from time to time. The entire fuel system will need to be drained and flushed, the fuel filter (https://www.yourmechanic.com/services/fuel-filter-replacement), which is in the fuel tank as part of the fuel pump, may need to be changed....

Check the throttle pedal position sensor (https://www.yourmechanic.com/services/throttle-accelerator-pedal-position-sensor-replacement) on the gas pedal and see if the wiring is loose or pinched. If the wiring looks good and is not damaged, then I recommend replacing the sensor. If you need further assistance...

Hi there. The glow plugs are designed to help start the engine even when the engine is hot. If the code is on for the glow plugs, check the glow plug relay and timer and see if its energizing as...

To be blunt, there is no specific number that we can give you. You have to understand that diesel fuel gels in colder climates due to the amount, and types, of paraffin wax that is used in the manufacture of...

Hi there. If your Tacoma is a 4x4, then check the transfer case and see if that is where the noise coming from. If it is, then the chain in the transfer case is slipping and needs replaced or repaired....

Hello. The blue smoke on startup is likely worn valve stems or valve stem seals, which leak a tiny amount of oil overnight, but burns it off quickly. Nothing to worry about unless it gets worse quickly, or smokes all...

Hey there. Unfortunately, diesel fuel (https://www.yourmechanic.com/article/what-type-of-gas-should-i-use) does not combust the same as regular fuel does in a gasoline engine. Eventually, the car will run out of regular fuel and die as the diesel fuel is injected into the motor. Once...

Hi there, thanks for writing in. Actually, you should only be shifting gears with the clutch pedal fully to the floor. However, there may still be some air in the clutch hydraulic line, and the clutch needs additional bleeding. It...

I personally prefer diesel over gas because they generally last longer. I would also go with Mercedes over Lexus but that is just my personal opinion. I have worked on both types of vehicles and would rather work on a...

Personally I would take the Mercedes over the Ford, but the truth is, diesels are undergoing a massive engineering revamping of their emissions systems. Emissions on diesels is new to the automotive market making these systems problematic until the manufacturers...
