Right we have changed my oil cooler so no more oil leaks which is good, however the oil pressure is different now ie LOWER than before we changed the cooler, we also vhanged the oil at the same time.
When the engine is stone cold the oil pressure is at maximum at idle,
when the engine has warmed up it idles at 1 bar on the dash
at 2000 revs its showing half pressure
at 3000 revs its on full pressure
Im not convinced that the oil pump is FUBAR as it was fine on pressures before although its always idled at 1 bar when warm.
Any thought on this? Could the cooler have an air pocket thats causing problems with pressure when the sandwich plate opens?
What does your engine make at
