PERKINS INDUSTRIAL ENGINES:
• Perkins 1104C-44/1104C-44T 1104C 4.4L Diesel (2000-2012)
MASSEY FERGUSON TRACTORS:
• Massey Ferguson 3425/3435/3445 1104C-44 4.4L Diesel (2003-2012)
IMPORTANT:
This valve cover gasket fits the Perkins 1104C-44/1104C-44T engine (4.4L 4-cyl). The 1104C is the Perkins-branded version of what Caterpillar sells as the 3054C engine. Found in Massey Ferguson tractors, JCB equipment, and many industrial applications. The cork/rubber material provides the correct compression for sealing — do NOT substitute RTV sealant in place of this gasket.
Failure symptoms: oil seeping from the valve cover, oil on the exhaust manifold. Cork/rubber gaskets dry out and crack with age, especially in high-temperature environments. When replacing, clean the cylinder head and valve cover surfaces thoroughly — cork residue must be completely removed. Inspect the valve cover for warping. Torque bolts evenly to avoid crushing the gasket — overtightening is a common cause of premature cork gasket failure.
⚠️ Fits Perkins 1104C only — not 1104D or later engines. Verify engine model.
