Okay, this I've always figured, but how do we really take care of it?

Besides running down to the Nissan dealer and paying through the nose for a

nissan filter and putting it on my Cleveland, the article mentioned

blocking the overflow in the block?  What was this?  Is there a way to

defeat the bypass in the filter and still maintain pressure in cold

situations?  They also mentioned doing this "defeat" on high-volume pump

models.  This piques my curiosity.



Anyone have any answers?
