Parts for your 2010 Honda Stream-Oil seals

2010 Honda Stream oil-seals — what they do and when to sort them

Oil-seals are absolutely fitted and relevant to the 2010 Honda Stream (RN6–RN9). Honda’s workshop manual for the R18A/R20A engines and 5-speed auto/CVT transaxles, along with the Honda Electronic Parts Catalogue, list multiple seals: front crankshaft oil seal, rear main seal, camshaft seals, timing chain case seal, and transaxle input/output and driveshaft oil-seals. Honda Service News and service manual procedures also detail correct seal installation depth, lubrication of lips, and crank/cam alignment during refitting — all clear indicators these seals are standard on this model.

On this Stream, oil-seals keep engine and gearbox lubricants where they belong, stopping leaks at rotating shafts and housings. They ride on machined surfaces and use a spring-loaded lip to hold back oil under pressure. When a seal hardens, wears a groove, or gets nicked during work, leaks start — leaving spots on the driveway, a whiff of burnt oil on the exhaust, or a low oil level between services.

As part of routine servicing, oil-seals aren’t replaced on a time or kilometre basis
