Am on the boat for a couple of weeks, so decided to change oil and filter.

Stuck the Pela tube down the dipstick hole, but wouldnt go further than an inch or so. Stuck it down the oil filler hole, but wouldnt go far enough. Stuck it down the special draining tube,, but it wouldnt go far enough.

I know I used the Pela last time I changed the oil, which was around December 2006, and I seem to recall it went down the dipstick hole fine.... it certainly went to the bottom of the sump, whichever way it went, because I got 6 litres out.

The dipstick itself will only go down if aligned correctly.

Any suggestions... has something changed in my engine? has the Pela tube expanded.

In the end I undid the bolt at the bottom of the sump, drained it into the bay, then mopped it up with cloths and Pampers, but I know it can be done with a Pela as I did it last year!!

Many thanks

Richard
 
just done a tmd22 with a pela, took all afternoon, turned out that we were sucking bits of carbon into the narrow tube. had this happen to a little suzuki pick up, dont know why but seems as if some engines will do this in the sump.

Hi Stu,

Which hole did you stick the pela down? My oil was quite thick and was very slow to suck up from the bay below the sump - hence the cloths.
 
Richard,

I havent used a Pela but do use the 'spherical' version whose name I cant remember. There is a narrow black tube which takes a bit of jiggling to get it round the first bend in the tube. Another option is to fit a pipe over the top end of the suction tube, clamped with a jubilee clip.

It took about 20 minutes to get all the oil out, but it was only just warm. Next time, I would get it quite hot first.

If I was to drain it out of the bottom of the sump, a tin foil baking tray would be in the well, first.

Best of luck with it
 
On our MD22LA there's a pipe on the stbd side of the engine that has a small rubber cap. There is a bend about half way down it but not usually a problem to get the tube past it. I only use one of the small brass pumps and pump the oil straight into an old oil container. Takes 10 min max but I do run the engine for 15-20 min first to get the oil reasonably hot. Once I've got all I can out with the pump, I remove the drain plug (which is just below the pipe I'm talking about) and drain the last couple of hundred mls into a flattish plastic container that has a sealable lid as I have to turn it sideways a little to get it out (about a pound from Tesco’s!). Never tried the dipstick hole and I'm pretty sure the one I'm talking about is the one to use.

Brilliant. thanks for the tip! Some of the simplest and cheapest ideas are the best.

I couldnt get it past the bend last time, and couldnt this time... maybe I need a different pump??

Anyway - it's done for now and, given the engine will be hardly used between now and next April, I can think about things between now and then /forums/images/graemlins/smile.gif
 
The sort of containers to try are ice cream tubs/boxes,chinese take away boxes,large yoghurt containers,margerine boxes etc.I keep a selection to try in the well underneath the engine when changing filters,impellors etc.You can then snap on the lid if you have to extricate the box at an angle.When servicing time is due we have to have a particular marg spread that month because it fits under my engine perfectly.
 
It is essential to get the oil pretty warm before trying to extract via a small bore tube, whatever pump is used.

Knock off the oil filler cap to ensure equalisation of air pressure as oil is removed.

Tip a quarter litre of fresh oil in when the old oil is pumped out - that way you get the last dregs of the old stuff without having to work in the sump area!

Remove the oil filter - low down in my case - and let whatever's in the feed pipe drain down over 10+ mins to remove all the old stuff.

There is also a pipe on the stbd side of my engine which I suppose is the same as mentioned above. I also had difficulty in getting a flexible suction pipe to get right to the bottom of this pipe and to the bottom of the sump. I did eventually get one fully down but it was taking for ever to suck the old oil out. For some unexplained reason I took this long flexible plastic pipe out and attached a larger bore plastic pipe to the top of the engine's pipe and sucked from there. All the sump oil was taken out quicksticks. I didn't measure the old stuff but it was about 5 to 6 litres. I assume the engine's stbd side pipe travels all the way to the bottom of the sump itself and so doesn't need a plastic pipe inserted. Hope this info helps.

[/ QUOTE ] Your post does not seem to answer my question but I agree with this statement . You can see it in the exploded parts diagram Part #24 going down (almost) to the bottom of the sump.

I beleive a pump was available to attatch to the top of #27 without the need for a small tube to go all the way down. The exact shape of #27 varies with different versions of the MD22 as does the design of the connection between #27 and#24
 
hiya richard
sorry for the delay. i stuck the thin black tube down the dip stick i tried all the other pipes and orifices and could undo them or couldnt get round them, (moody 46) the first attempt sucked up some crud but when i got a clean suck it didnt take long.

Hi Richard, glad to hear you are aboard! Hows my tatty canvas temporary bimini faring out on C'est Formidable?

The boat looks well, but cant see any evidence of a bimini type thing. Perhaps it didnt work as well as it should, and the lads have taken it down?

Hope all is well....
