Vacuum pump -- oil extraction

[Jellybean]

I know some of the modern cars are designed to accommodate using a vacuum oil pump to drain the oil , I presume it is possible to use one on the Supra without damaging anything ?

[pedrosixfour]

Totally safe dude.

Thanks Damien , worth asking than damaging anything

yep ive done it a few times , got mine from lidls, changed the supra and the truck easy , getting the filter is the hard part

Does it do a better job of removing crud in the bottom of the sump than the usual gravity drain method? It must be a small-bore tube it sucks through (if it fits down the dipstick tube).

Depending on sump plug location, I recall that it's pretty low down on the 2JZ sump, you may not get as much of the old oil out with the suction method as you would using the usual method. You can increase the amount of oil you do extract by simply getting the dipstick tube into as low a position as possible by having the car on an incline or something.

 

I'd nearly be as well off just using the suction method on my own Navara, the sump drain is set so high up that, unless I jack the whole left side of the jeep off the ground, there's probably still half a litre of old oil left in the engine when it stops draining. Stoopid design.

 

And you should see where Nissan stuck the oil filter on that engine!

at the end of the day not really going to hurt if a small bit is left , not all of it comes out of the drain hole , saying that youve just warmed it up prior to either draining or extraction so some is still up in the engine.

Ah yeah, I know. I do warm the oil up prior to draining, but I'd also drain the oil first with the jeep jacked up on one side and then leave it draining like that while I carry on with the rest of the service.

 

When I use that method the engine then takes exactly 7.5 litres to refill so I can just put that quantity in with no doubts or measuring and I get away with only buying a single 5 litre can of oil every second service.

I was going to use it to extract the majority of the oil then drain the rest via the Sump plug , not as messy going via the Sump plug especially when she is on axle stands

For a second there I forgot you were mental!

[peter richards]

any tips for getting the filter off from the top ,or is it impossible
