Vacuum oil change

[mjb]

Don't bother trying on a HDi90 - you can suck about a pint out and that's it.

Another £50 down the drain, and now I've got to see if I can spend even more money getting someone to change the sump in the next couple of days

Works fine on my 110. So long as you use the long probe type sucker.

odd, i'd have thought it'd be the same. surely being on a very slight upwards incline couldn't have had that much of an effect? I expected to miss a couple hundred ml of oil, but not all of it...

I used one of these on my HDI 110....

It seemed to get most of the oil out. Reason why I got the pump was that first time ever
on a car, getting the sump plug undone had defeated me. Bit of a messy faf cleaning the pump up afterwards.

Oil change due again in a few hundred miles, so this time around I've decided to just do it the traditional way.
To prepare, I borrowed some car ramps, for extra height, elbow room, and leverage. The sump plug loosened.
Have also done something I've never done before ... bought a replacement copper
plug washer, so no need to tighten the plug to infinity to make the seal.

It's probably not completely the same thing but having seen the bottom of a 1.6HDi dipstick tube I'd be amazed that a pump could get all the way through it and into the sump (without a lot of wiggling & farting about) because it has 2 right-angled bends on it. That's probably why their dipsticks break...

Until a few years back I'd never replaced a copper washer either, except when rebuilding engines. Never needed to over-tighten one, never had one leak either

I've been thinking of using a syphon because last oil change the threads stripped out so bought one of these.

Worked a treat but needed a better washer me thinks it does drip now and then... So syphon or risk being in the same boat again and have to order the larger size tap and plug set? Not decided yet but need to soon.

Definatley the best way is the old way of removing the sump plug you have more chance of getting any nasty crappy deposits out the bottom of the sump that way.
I have only had one incident a few years ago on a Renault clio when I overtightened the sump plug after doing a oil change and crack! I had cracked the aluminium sump
lesson learned...............don't overtighten things!!

Last time I dropped a sump after sucking it dry, it was really dry and nothing in it at all. But we do have good commercial stuff at work. And we also come across new stuff with no sump drains at all, so it seems to be the way things are going. And I guess you never get all the oil out what ever way you do it, there will always be some lurking in some bearing or oil way some where.
