Clever Way to Suck Oil from Dipstick without Turning on Engine?

[Meggy]

 I had a flood on my boat and lots of water got down my oil dipstick. Now I'm keen to get that oil/water out.

Really don't want to start the engine as I've already (unknowingly) run the engine about 5 miles with water in it.  

Today I tried to suck it out cold using a 12v pump and 4m (inner diameter) hose down the dipstick. But I guess the oil was just too viscous.

Anyone have any ideas? Should I heat the oil sump with butane torch or something? Here's the 12V 60W oil pump I bought which has disappointing suction;

Is there something with better suction?

Drain it from the oil drain plug?

There will be a drain plug, and although it may require a certain
degree of contortionism to access, I'd expect it should be accessible
without removing the engine.

There's not enough clearance to get to the drain plug. Its in my boat.

[Toby Catlin]

Any way to heat the oil without turning the engine? A gas burner under the sump or something? Not a car so my ideas are limited.

Is there a oil filter? could this be removed to help drain?

We do have some fairly high suction pumps, though they'd be wrecked if they got water or oil in.

If you pass the tube into a large container,  and then from the container (sealed) into the dipstick, you should be able to keep the oil out of the pump. Make sure the pump tube is right at the top of the container to keep it out of the oil at the bottom.

Is the tube stiff ? If it's not, the pump vacuum will crush it so it closes itself.

[Dan Reid]

If you can't get to the drain plug, one of these is probably the best option

What Vyizis describes is a manual version of what Artag describes and will be the easiest and most portable solution IMHO 

I have used a similar arrangement and it works well (both approaches) with Artags solution you need a solid buffer container (I used to use you guessed it gas containers ) and setting it up can be a "quiet technical" you don't need to use the a high vacuum pump though

You want a catch-pot inline to prevent that happening. Like an aspirator.

yep that's what I mean by buffer container - aspirator or what you see on the suction line in hospitals is perhaps a more "public" friendly description 

because of the viscosity, head and geography or lay out the main point is it needs to be sucked out not pumped however if you let any of the oil you are sucking into the pump its not good for the pump

What about this?

I'm not clear on Adrian Godwin's line;

"If you pass the tube into a large container,  and then from the container (sealed) into the dipstick, you should be able to keep the oil out of the pump. Make sure the pump tube is right at the top of the container to keep it out of the oil at the bottom."

Are you saying I should use one of the stronger Hackspace pumps but with a sealed container between the pump and the dipstick to collect the oil?

I bought one of those Silverline transfer pumps awhile back for water Des Quilty and it was really, really difficult to use (even for water). I guess it wouldn't hurt to try it though...

[deanforbes]

Im not surprised you battled with http://www.ebay.co.uk/itm/Silverline-Oil-Fluid-Suction-Transfer-Hand-Syringe-Gun-Pump-Extractor-/261571602717?hash=item3ce6e1e91d:g:xiYAAOSw3ydVvGo~

I am sure  http://www.amazon.co.uk/Pela-6000-Oil-Pump-Extraction/dp/B002EJ2GUC will do the job 

you need a "reservoir" for the fluid while it is being extracted and to hod the vacuum

I have an even cheaper oil suction syringe type (without the valves the  Silerverline) and use to "pump" the oil into a separate container.

I just suck the oil out of the dipstick hole (500ml per stroke) and then remove the pipe and push the oil into a suitable oil container, repeat until all the oil is out.

On some engines its a bit difficult to get the hose right down into the sump with a 1cm diameter hose, so a little connection to a smaller hose might be worth investigating.

The Pela seems to be a good bit of kit, but obviously, more expensive and a lot more bulky if you want to store on a narrow boat.

I can bring my syringe in if you want to take a look..

I really don't think this is a good idea if this is a petrol engine at all for reasons of explosion risk and possible mutilation/death due to petrol explosion!

Whut? It's oil they're syphoning and boats usually equal diesel in my experience.

[Peter Adams]

Depends what sort of boat, I only got boat from the conversation.

I tend to have a bit of a hair-trigger when it comes to possible accidental self-immolation. I'm not quite sure of the psychology behind it but I think it may have something to do with me almost setting fire to my own testicles.

Tangent.

Great news!

A fellow boater loaned me a Pela 6500 vacuum pump and it works! It's taking AGES (5 liters in 72 hours). However the oil level is halfway down according to my dipstick.

So I'm halfway through and its going to take another 3 days but at least its coming out. Once I get out as  much possible I will fill with oil, run it an hour and dump it again. I think I will do 3 oil  changes.

Still undecided whether I should use a flushing oil though. Opinions are mixed on the internet. I've hear some horror stories but my engine is filthier than most.

Any thoughts on engine flushing oil?    

Here's the magical miracle fabulously great vacuum pump.

Hi Megan,

Are you REALLY sure there is not means of draining out the oil, from the engine. Oil changing is very much a basic maintance procedure. Whilst I am no marine engineer it seems REALLY odd that they would be making life that hard for themselves.
