Description
Overview:
This Gasket, Rocker Cover for Loncin G390 engines (part no. 380840425-0001) is a genuine Loncin component that seals the rocker/valve cover to the cylinder head on OHV petrol engines. The gasket is made from durable, oil- and heat-resistant gasket material designed to maintain a tight seal under normal engine operating temperatures. It prevents oil leaks, reduces misting, and helps protect the valvetrain by keeping contaminants out. Engineered to match the original profile and bolt-hole pattern, it fits correctly without modification. Suitable for Loncin G390-series units and selected models such as G270F (see full compatibility list below), it is a straightforward replacement during servicing or after valve clearance checks. A reliable seal helps maintain engine efficiency and long-term performance. This is a Genuine Loncin Part.
