On certain Peterbilt, New Medium Duty chassis that are equipped with the optional engine intake air Pre\-Filter \(option code 3281830\) the Pre\-Filter may become clogged and cause premature failure/breach of the primary intake air filter. In some cases, a failed/breached primary filter can result in unusually high engine RPMs and high crankcase pressure. However, a failed/breached primary filter may not exhibit any of these symptoms. The immediate fix for this issue is to modify the Pre\-Filter by removing the filter media from the base plate, and then reinstalling the modified Pre\-Filter base plate.
