Why I need to do this, will get to later. For now:

Rigged up a nice little drill-pump evacuation system with semi-rigid 1/4" tubing, just longer than dipstick, a couple of adapters and $8 drill pump. Fed intake into dipstick tube until it stopped (~ same length as dipstick, as I had marked on tube).

Started with the drill and voila nice flow of warm oil within 60-90 seconds. Draining right into a 5 liter container via hose on pump outlet so life was good, until after 2-3 min...

Intake tube begins sucking air and pretty soon my nice initial flow had turned to a dribble. Can't feed tube any further into dipstick receptacle. Total removed was just over a liter, so LOTS more to go.

The pumping aspect of this went about as well as I could hope. Guessing someone here is familiar enough with the engine innards to know why the intake fed through dipstick tube can't get to bottom of sump? (I'm assuming this is what's happening). Or perhaps another reason I'm not able to keep continuous flow to evacuate all the oil?

Thanks all --

 

The end of the dipstick tube ends just a little bit below the normal oil level, which is a few inches above the bottom of the sump. The tube is also crimed at the end so your tubing won't be able to pass that. Don't waste your time. Is your drain plug stripped?

 

Thanks Ahsai for saving me cycles trying to make this work. Sounds like I expected.

Yes drain plug stripped... Long story, not entirely by my hand but it is stripped. Have tried several options to get it off and afraid next will be removing pan.

Ideas or suggestions welcome.

If it's a steel plug, dremel a / into the face and use a large slotted-head screwdriver to unscrew it - or drill it out slightly and use a reverse-threaded screw extractor to back it out.

 

This.

I usually use a larger tight fitting flat head and use a vise-grip around the handle of it for more torque. This has worked for me on quite a few occasions(especially with those pesky rotor screws).
