quick questions:
on hondas, specifically the b series engines, where is the oil filtered as oil travels through the engine. as in: what is the order? does it go pan>pickup>pump>filter>oiling surface>back to pan
im not sure how to word this question properly, thanks in advance for any assistance.
also, is this where the filtering takes place in other engines also? such as other brands (nissan, toyota, mazda, chevy ect. ect.

As the motor is turning. the pump pulls oil from the pan through the oil pickup. from there it goes straight to the oil filter and out the filter back into the engine to lubricate all the needed parts.

 

ok, thank you. this brings up one more question.
on the filter, there is the main hole in the middle, and the smaller holes around the circumference. which is the inlet and which is the outlet?
thank you

In from the pump along the outer ring of smaller holes and into the block's main oil passage through the center of the filter.

 

There is also an anti-drainback valve in the filter that is supposed prevent gravity from pulling the oil from the top of the engine back into the pan. I say "supposed to" because some filters use very crappy materials for this part and it ends up failing before it is time to change again.

While that scenario is not the end of the world, it can cause premature valvetrain wear, especially if the car does lots of on/off cycles.

OR if you get cheap *** filters (specially with oil change shops) they don't have the drain back valve....

I didn't realize they made filters without the drainback valve, but it does not surprise me. I always thought Fram's cardboard assembly was as cheap as it could get...
