Hi people,

I drained my oil in my civic, and let drain for 4 hours, only cuz I had to leave for a short trip and figured it can only benefit draining . Then, after the 4 hour drain, I unscrewed the filter expecting the usual drip/slop during the unscrewing, and no drip/slop......upon inspecting the inside of the filter, there was absolutely NO oil left!

It had been unusually long period between change this time, I figured about since March (Bad me), and maybe the silicone anti drain seal/valve in most filters broke down?? Could that be the only explanation?

Thanks!

 

it could of actually drained down slowly.

 

It should not have drained slowly. The anti drain back valve is bad, which is really bad for the engine because the engine will be starved of oil everytime it is started

 

With the filter facing downwards, poke the silicone anti drain back valve to open it. Does more oil come out? If yes, the filter is fine and did it's job

 

Hmmm, good tip, ineffable. I didnt know that. Ill try it. Thanks!! (next time Ill replace sooner).
