The Cummins Engine Valve Cover covers the valve train on EPA10 15-liter ISX and QSX engines with XPI fuel systems. Oil running down the head or onto the exhaust below is the usual sign the old cover has cracked. A cracked cover can leak oil onto the engine and hot exhaust components below it, creating both a mess and a fire risk. The Cummins 3689759 seals the top end again and keeps the engine bay clean.
