VP D2-40- Oil Change

[CJ13]

The D2-40 engine is said to contain 6.5lit engine oil.
Using my Pela Extractor i get about 4.0lit out thro the dedicated 'Oil Suck Out Pipe' and an extra 0.5lit thro the Dip Stick Pipe, leaving around 2.0lit old oil in the sump. Has anyone else had the same problem? & if so have you solved it?
I did wonder if the 'Oil Suck Out Pipe' is designed to have the extraction pump clamped over it rather than sending the fine Pela tube down the pipe. For me this means cutting the Pela pipe which i don't want to do on the offchance.
All advice appreciated.

If the "suck out pipe" is anything like the one on my MD 22, it would probably be quite difficult to pass a tube down it. The suction pipe from my pump just goes over the pipe.
As to missing oil, there will be some in the oil filter.

I would have said from looking at the exploded diagram that provided the Pela suction goes right to the banjo at the bottom of the oil extract pipe it should remove all the oil.

Like wise if it goes down the dipstick tube and reaches the bottom of the sump..

The book figure for the volume of oil is probably the volume required by a dry engine. It ceratinly includes the oil in the filter. Its seldom possible to recover that much, even when taking out the drain plug ( is that an option in your installation?)

I have a similar issue in a D2-55, except oil capacity is 10.5 litres and I never get much more than 8.5 litres out of it. I have an oil extractor pump permaneantly fitted to the 'oil suck out pipe'.

D2-40 oil suckout

I also have a D2-40. I find the Pela sucks the oil out through the suckout pipe quite well. However, I had to take the sump off my engine last season as the engine had been flooded with water. I had sucked all the oil possible out with the Pela, but there was still about an inch of oil left in the sump when I got it off.

The drain plug in the bottom rear of the sump is mounted in an area of the sump which during manufacture has been pressed upwards so that the surface of plug inside the sump is at least an inch above the bottom of the rest of the sump. So removing the sump plug will not drain all the oil. I believe the suchout pipe aims the Pele suckout pipe onto the same raised portion and this is why it doesn't reach to bottom of the oil.

Hope this helps

Lofty

After you've refilled with new oil and run the engine for a short while, does the oil appear 'clean' on the dipstick or does it look slightly grey/dirty?

It should be completely clean. If the oil appears even slightly grey or dirty then too much old oil has been left in the sump (IMHO).

I think you'll be very lucky to end up with anything other than grey or dirty looking oil. ( even oil that looks as black as the old stuff )

You might be lucky but much depends on how much remains trapped in oil ways etc and how long you are prepared to spend allowing it to drain and sucking out the last of it.

Have you changed oil in a modern boat engine lately? I have been doing it for years and the new oil should appear shiny and clean if you have extracted the old oil properly.

This was certainly true on my MD22 that I maintained for 13 years. Hopefully it will also be the case with the D2-40 in my new boat - but this thread has me slightly worried!

No not a modern engine its true. Boat or other wise.

On the old MD11 we used to suck out what we could via the dipstick hole. You could not get it all out that way but it was possible ( just) to get something under the drain plug and get the rest out from there.


What is it about this thread that has you worried?

The fact that you apparently can't get the last 2L of dirty oil out of the D2-40.

I haven't had the first service on the new engine yet (D2-40) but I will not be a happy sailor if this is correct.

I'd be a bit unhappy too if you really could only remove 2/3 of the old oil. I'd think that can't be so. The oil suction pipe is fitted low down on the sump allthough entirely external whereas it's partly internal in the MD22 isn't it?

I'd think the OP's problem might be not getting the Pela suction right to the bottom. Or that there was not a full charge in there in the first place

I guess you will attach your pump to the top of the tube.

Correct and it must reach almost to the bottom of the MD22 sump as it allows (almost) all the oil to be extracted.

I guess you will attach your pump to the top of the tube.

That's how I used to do it on the MD22 and it left the sump almost 'dry'.

I'll try that way first on the D2-40 - when I am finally 'allowed' to touch the engine myself without invalidating the warranty. It won't be for at least 12 months, though, and could be 3 years if I follow the Dealer's interpretation of the warranty conditions.

 

[Lofty]

The oil in my D2-40 always appears clean, but then it only has 200 hours on the clock. I wonder how long it will stay that way.

Thanks for the replies.
I actually removed just over 4 lit oil + the filter capacity, so less than 4.5 lit total.
Measuring the sump below the suck out tube, this seems to hold about 2 lit. Seems a strange design, & i don't understand why it's necessary?
