20930510 — Crankcase Breather Filter Cap 20930510 For Marine Engine Volvo Penta Vetus Vd 4.140 Vd 4.120

This crankcase breather filter cap is designed to filter the air drawn into the engine crankcase, preventing contaminants from entering and ensuring proper crankcase ventilation. It is constructed from durable materials that resist engine oil and heat, maintaining its filtering efficiency over time unlike a clogged or damaged cap. Operators may observe increased oil consumption, internal engine sludge buildup, or oil leaks from seals and gaskets if this cap is faulty or its filter is blocked.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A blocked or damaged breather cap can lead to increased crankcase pressure, causing oil to seep from seals and gaskets. If left unaddressed, this can result in excessive oil consumption and the formation of sludge within the engine. Prolonged operation under these conditions can accelerate engine wear and reduce its overall lifespan.

Installation Tip

Ensure the mounting surface on the valve cover is clean and free from old gasket material before attaching the new cap. Do not overtighten the cap, as this can crack the plastic housing.

Service Note

Inspect the valve cover gasket and the PCV system for blockages or leaks when replacing the crankcase breather filter cap.
