What causes high lube-oil pressure in Man E3268 LE222?
- SStephanie ReedSep 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.
