Key Features
- Genuine OEM Sealing Integrity — manufactured to the original material and dimensional spec that keeps valve stem oil consumption in check on these RAMMAX roller engines.
- Serial-Number-Specific Fitment — validated for RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N 1534188); always cross-reference your serial number before installation.
- Drop-In Installation — designed to seat on the valve stem exactly as the factory original, requiring no machining or adaptation to the cylinder head.
- Prevents Oil Migration Past the Valve Guide — a properly functioning valve stem seal cap keeps engine oil out of the combustion chamber, protecting performance and reducing exhaust smoke.
- Correct Part for Authorized Service — using the genuine Multiquip 50405200 keeps engine repairs aligned with Multiquip service documentation for these roller models.
A valve stem seal cap fits over the top of the valve guide and creates a controlled seal around the valve stem as it moves in and out during engine operation. Its job is to limit how much oil travels down the stem and into the combustion chamber. When this seal wears out or hardens with age, oil begins burning in the combustion chamber, causing blue exhaust smoke, increased oil consumption, and potential buildup on the valve itself. Replacing a worn valve stem seal cap restores the proper oil barrier and helps the engine run cleanly and efficiently.
