I’ve read quite a few people mentioning that you can only get between 3.5-6L of oil out of the engine by gravity alone, with the rest needing to be pumped out.

I’ve acquired an oil pump for just this job, however instead of using an educated guess and putting the tube into deep into the sump, (probably not right anyway considering it’s a dry sump) does anyone have definitive experience of where to feed the tube?

I am doing the same on my Tuscan. This lock-down has given opportunity to do all the jobs that were waiting for spring.

I have a Varley Sagaris book and he say's:

Push pump out tube to back of sump (gearbox end) to get what doesn't come out of the sump plug.
Remove oil gallery hose from the cooler and purge with fresh oil.
Remove oil pressure sender hose and purge with fresh oil.

Not done it yet so not sure if it works.

If it works, please do update me. If it works, could you take some pics of what to take off etc.

Hopefully you end up with a right result 👍🏻

Yes - I've just done mine. There is a drain plus at the rear of the sump below the starter motor but it's only accessible if you remove the gearbox, so that's a non-starter. I believe on later cars it might be accessible and I read of one owner who modified the bell housing to gain access.

Back to reality - on the left side of the engine, just below the front of the alternator and behind the oil tank return pipe, there's a second drain plug. I got a suction tube in there and removed at least another 2 litres.

There's also a second oil filter you can clean - it's on the oil tank behind the oil return hose. It's a small gauze brass job that is easy to remove and clean. You might need some RTV silicone to re-seal.

You can get about 9litres out draining methodically.

Release all plugs, the release the unions on the pipes at the oil cooler, the tank etc. All of this lot holds a lot of oil.

Raise the car an just let it drain away.

Good work, I’ll try mine this weekend and see how much I can get out.

Did you use an oil pump to pump any last bits out?

Used one of these. Bought at Machine Mart but available online elsewhere too. Originally got it to top up hydraulic fluid (another p.i.t.a.) but works really well here. I'm sure there are many variations you could source.
