also gnasher, your point about the weep will ineviably get worse is true, so i will look to permanently stop it up with some bonding agent etc once it gets to the point where it is worse.
your other point about properly draining so that you are removing as much old oil as possible is also a very good point , which is exactly why you need to get as much out as possible, i definitley got 3.5 litres of old oil out, which is what the manual says oil &  filetr 3.5 litres req .


however a dry engine following rebuild takes 4.2 litres.  this must mean then that you can never remove the remaining old  0.7 litres from any style of oil drain so there is always .7l of old oil kicking around in your engine stuck in places that it cannot drain back to the sump . no way to remove 100% of all oil without disembly.
i think 3.5 is the max you can get out and just as long as thats what you can get out , this pump method is equal to a conventional drian. you cant drain anymore out than you can pump out.

What manual are you reading?


It's a 2.5 litre sump, or I use 2.8 litres with a filter change as well.
My window is not see through any more so I have to use measurements.
