Feeding a pipe through dipstick for an extraction oil change
Discussion
Tried to impress the wife by buying her an oil extraction pump for her Hyundai but just found no matter how I try I cannot get the pipe into the oil at the bottom. Feeds down OK but then it feels like it hits a door and I can see I am indeed about 2 inches short of how deep the dipstick itself goes in.
Am ordering a smaller diameter pipe but wondered if anyone has tried these kits and if I am doing something else wrong? Tried the pump with oil in a can and it drew it out impressively so the pump is fine.
Am presuming the channel starts wider than it ends as it really seems the only section I cannot get to is indeed where the dipstick itself measures the level?

I have literally, in the last 30 mins, done an oil change on my brothers pug 207. Its only a smaller capacity engine and I think I drew just over 2 litres out. But it took a while, and I needed to daisy chain two of the pipes together to get it down the dipstick pipe fully (with the smallest diameter pipe being the one that goes all the way in and then that is connected to a bigger pipe). The poor thing hadn't had an oil change in 6 years and it was like treacle.
Once you've built up a pressurised system I see no reason why you couldn't leave the pipe where it rests and let the syphon action do its thing.
What is the suction equipment you are using ?

2l doesn't sound like much. Once you've built up a pressurised system I see no reason why you couldn't leave the pipe where it rests and let the syphon action do its thing.

Thanks - is a manual pump, draws it off into a 4 litre bottle. A cheap and cheerful ebay effort but it does seem to work well. When I used it on the oil in a container it drew it up surprisingly quickly after just a couple of pumps.Once you've built up a pressurised system I see no reason why you couldn't leave the pipe where it rests and let the syphon action do its thing.

That is what I thought. Either the engine was very low on oil to begin with or there is lot remaining in there.
2.5l capacity to 2.75 Inc the filter It was in a right old state I have to say, like treacle. Amazing it was still working. Although I did notice a fairly long standing oil leak from one side of the head cover.
I'd guess it is just a case of replacing the gasket hopefully but the poor thing hasn't been looked after at all. Even the coolant looked utterly rank and years old.

That is a small oil capacity, sounds like it needs a bit of TLC.It was in a right old state I have to say, like treacle. Amazing it was still working. Although I did notice a fairly long standing oil leak from one side of the head cover.

Twisting as you lower the extraction tube to the depth of the dipstick usually does the trick.
In very rare instances I've had to utilize a smaller dia pipe ..Not a problem, just require a larger mug of coffee whilst I wait.
E.T,A Volkswagen group often use a narrow orange plastic upper section which the larger tube struggles with.

I've done this for years on Volvo V70s and Merc E class.
Sometimes the tube goes straight in, down to the bottom.
Sometimes it takes a bit of prodding.
Sometimes it baulks, takes a bit of effort and time, then seems to pop through what feels like metal mesh (hope not!)
It seems to be more difficult when the tube is cold.

Thanks all - I do think more and more that yes, the tube is a little too wide. It slips into the dipstick tube easily but I can see now while its channel/inner diameter is 5mm, same size as the dipstick itself, the outer plastic runs it to 7-8mm or so - visibly wider than the dipstick.
Have ordered a 3mm tube (so hopefully 5mm in all) and will see if that does it.
Hope it does as these extractors seem good for interim oil changes.

Don't cars come with sump plugs anymore?
(Serious question)
Yes, but why would you scrabble around underneath and get covered in mud, dirt and oil, when you can sit clean and tidy with your cup of tea waiting for it to come out the top? Doubt the sump plug on my 2010 car has ever been out in 11 years. (Serious question)
Just use the wire thing used for hanging net curtains.
It's basically a spring, wrapped with shrinkwrap.
Goes round bends then straightens up at the bottom.
It's all most Vacuum kits are supplied with, only white and a 10th of the price.
Just make sure you seal it well onto the thicker tube, to prevent drawing air, Duck Tape works well !

Don't understand these kits at all!
Car needs oil changing.. oil is most contaminated at the bottom bowel of the sump. This is why they fit magnetic crap catchers to the drain plug.
Whoever thought that sucking some of it up through the dipstick pipe is deranged! You want ALL the oil out not some of it.
Do it properly or don't bother at all.

Do you really believe modern cars spit bits of metal out into the sump nowadays?Car needs oil changing.. oil is most contaminated at the bottom bowel of the sump. This is why they fit magnetic crap catchers to the drain plug.

It's a myth.
Some cars don't even have Sump Plugs!
Sorry, I'm old skool, always used to change (and flush) the oil on my cars, Spitfires, Capri's, Seirras, Granadas....never a problem running it up some small ramps, and if you take it to a stealer they used to put it up on a ramp.
I appreciate it's a lot easier sucking it out, but you can't tell me all the bits of swarf at the bottom of the sump are completely removed.

What swarf?I appreciate it's a lot easier sucking it out, but you can't tell me all the bits of swarf at the bottom of the sump are completely removed.
There may be a little sand leftover from the casting process. But that comes out with the first oil change.
Machining these days is an incredibly good, clean and tight process.
Nothing like the 1970's cars you are talking about.
Most machining work being done on the Alloy Head, not the Cast Iron block! So magnets wouldn't work anyway.
You don't even have to 'Run a Car in' these days, so good is the whole process.
