The big difference between cold and hot is concerning me after I just rebuilt the engine due to lack of oil pressure caused be loose oil pump cover bolts.
Workshop manual for CRD says should be more than 28psi at idle, more than 57psi at 2000rpm at normal operating temp. However what is normal operating temp? as this seems to have a huge bearing on pressure.
trying to work out if this is normal or I have a problem.
