Engine Valves
 

Hi,

I am busy replacin my valve seals and just wondered how, if at all, they get lubricated? Does anyone know about this. Do they just rely on the assembly lube?

Cheers,
Daniel.

Hey Daniel, and ...:welcome:. What kind of bike/engine are you referring to? With the bike info, you may get more specific answers to your question. Most common in modern engines is forced lubrication or, a combination of forced and splash lubrication. I found this video for reference. Hope it answers what you were looking for.
