The drain tube screws into a pipe that goes to the top where the cap screw is. The only way that I can see for the oil to get out of the canister is through a little hole near the top of the tube. Is that it or am I missing something? | | | | | Joined: Mar 2007 Posts: 4,215 Moderator | | Moderator Joined: Mar 2007 Posts: 4,215 |
You would be surprised how much oil can go through that little hole.

That hole controls oil flow through the filter so there is not enough flow to drop the oil pressure. With 20-30 PSI of pressure, plenty of oil will flow through the filter, particularly with the engine at normal temperature.
