Excessive oil pressure due to faulty oil pump on Dodge Ram Wagon B350

The engine may exhibit excessively high oil pressure at cold start up. This may lead to distortion of the oil filter case. Inspect the oil filter case for any signs of distortion. If the case is distorted,  Connect an oil pressure gauge to the engine and start the engine while observing the readings. If the pressure reads above 80 psi, replace the oil pump.
