trying to solve a problem, have a code for the ocv solenoid, pulled and replaced as it was easy. Also decided to check and clean the ocv filters, front one was fine, no sludge and wet, rear was was completely dry, no oil has been going through there for some time. Anyone hear of this. It runs fine and oil is changed routinely. after valve was replaced, ran for a while and code returned. pulled filter again, still dry as a bone..
