What causes high lube-oil pressure in Man E3268 LE212 Engine?
T
Tiffany DavisSep 3, 2025
If the lube-oil pressure is too high in your Man Engine, it could be due to the engine being cold, see "Fuels, Lubricants and Coolants...." Another potential cause is selected oil viscosity is inappropriate for ambient temperature (too thick), which requires remedy from manufacturer service. Other possible issues include a faulty oil pressure indicator, a safety valve in the oil circuit that is faulty (does not open), or oil lines/oil ducts that are clogged.

Christopher SerranoSep 1, 2025
If the lube-oil pressure is too low in your Man Engine, it could be due to several reasons. The oil level in the oil pan might be too low, see "Fuels, Lubricants and Coolants...." Another cause could be an engine temperature that is too high, which requires remedy from manufacturer service. Other potential issues include a faulty oil pressure indicator, selected oil viscosity is inappropriate for ambient temperature (too thin), oil in oil pan is too thin (contains condensation), heavily worn bearing, oil pump gears heavily worn, safety valve in oil circuit faulty (does not close, spring is worn or broken).

If the coolant temperature is too high or there's a loss of coolant in your Man Engine, it could be due to several reasons. The coolant level might be too low, which requires remedy from manufacturer service. Other potential causes include air in the coolant circuit, a very dirty radiator with clogged fins, a V-belt for the coolant pump that is not correctly tightened, a faulty or leaking cap on the expansion tank/radiator, a faulty temperature display, a coolant pump that is leaking or defective, a faulty thermostat that does not open, or coolant lines that are leaking, clogged, or twisted.

Why does Man E3268 LE212 have high gas consumption?
W
williamsedwardAug 29, 2025
High gas consumption in a Man Engine can be attributed to several factors. The gas quality might not meet the regulations, see "Fuels, Lubricants and Coolants...." Incorrect ignition timing can also be a cause, check intake vacuum. Additionally, a dirty or leaking charge mixture cooler requires remedy from manufacturer service. Other possible causes include leaks in the charge mixture ducting, valve seat leaks, a clogged air filter, or a dirty exhaust gas recirculation cooler.

What to do if Man Engine starts but does not reach idle speed?

Thomas TapiaAug 27, 2025
If your Man Engine starts but fails to reach idle speed or stalls, one potential cause is that the quality of gas does not meet the specifications or is contaminated. See "Fuels, Lubricants and Coolants...." Another reason could be that the throttle valve does not open, the actuation level sticks, or the actuator is de-energized or faulty, which requires remedy from manufacturer service. A clogged air filter can also cause these symptoms.

Why is my Man E3268 LE212 Engine showing poor performance?
B
Brittney HarrisonAug 26, 2025
Poor performance in a Man Engine can stem from several issues. The air filter might be clogged, requiring remedy from manufacturer service. Other potential causes include a clogged exhaust pipe, leaks in the air intake pipe, a dirty or leaking charge mixture cooler, leaks in the charge mixture ducting, or a turbocharger that is leaking, faulty, or dirty. Insufficient compression in the cylinder or a pressure difference of more than 3-4 bar between the cylinders can also lead to poor performance.

mgonzalesAug 25, 2025
If your Man Engine struggles to start or starts poorly in cold conditions, a faulty spark plug could be the cause, requiring remedy from manufacturer service. Other potential issues include a faulty ignition cable, a faulty ignition coil, incorrectly set ignition timing, a starter that turns slowly, a battery with insufficient charge or damage, or a voltage drop between the battery and the starter that is too high.

If your Man Engine struggles to start or starts poorly when warmed up, it could be due to a faulty spark plug, which requires remedy from manufacturer service. Other potential causes include a faulty ignition cable, a faulty ignition coil, incorrectly set ignition timing, or insufficient compression in the cylinder or more than 3-4 bar pressure difference between the cylinders.
