Engine Oil Sump Pump

[Seah0rse]

My search for 'Oil Pump' produced 500 results but none of the threads I looked at seemed relevant. So, I would be grateful if anyone would recommend a suitable self priming pump for getting old engine oil out of the sump through the dip stick hole as I am now doing my own engine servicing. I would consider either electric (12v) or manual.

Thank you.

You want a Pela.

Warm the oil ... stick the Pela tube into the dipstick hole ... pump up to 20 times ... sit back.

The vacuum created sucks the oil into a bowl, and keeps it there until disposal.

No mess.

The Pela is the business. Comes in several sizes. Also does a quick oil change on the car.

If you Google "Marine sump pump" you should get a few good links.

Agree a Pela is pretty good, if perhaps overpriced for infrequent use. The small brass pumps are about a quarter of the price and OK for occasional use, with the big advantage that they are easy to stow aboard. Where they fall down is in the suction valve at the inlet end. Some have a flap valve made from some sort of rubber, whereas others have a ball bearing. The flap valve material degrades quite quickly, loses shape and fails to seal. Before buying one, give it a shake and listen for the ball. If it doesn't rattle it is the wrong type.

jabsco do a little drill pump which works, is little effort and useful for lots of things, it's about 30 quid. Of course you also need a drill to make it work but if you use a cordless drill on the boat it might be of interest.

I've used several manual pumps, including the Pela type, and found them all more or less messy. The best system I've ever had, by far, was a plumbed-in 12v electrical pump - the hitherto tedious business of changing oil became quite simple.

Some engines have the provision to connect a pump (permanently maybe) other than by using the dipstick hole. Better, because the dipstick hole is so small, if it can be done. Check the manual!

If you want to keep the pump on board follow Vyv's advice but it can be a slow and messy process if you are not careful.

If you do not need to keep the pump on board then go for one of the Pela vacuum extractors.

You'll need to warm the oil up well to suck it up a tiny pipe, which ever type of pump you go for.

Be careful not to drop bits of plastic tube down the hole into the sump. It can and does happen!

Mine is not a Pela but it is identical. It's a Seago 6-litre.

I think I bought it from Arthur's Chandlery, Gosport.

One of the most useful things I ever bought.

Thanks for all the replies, suggestions and pointers.

My engine is about 45 years old ~ a Ford marinised by Parsons (and still going strong!) so dip stick hole is my only option. The Pela looks great but is possibly a bit big for permanent on board storage (plan to go long term cruising.) I have done the suggested Web search and see Mailspeed Marine do a more compact sump pump and I will ask if it is flap or ball valve.

Betas have them built in !

Force 4 do two types of pump, one has a spherical chamber and the other is cylindrical. The former is the cheaper by £15 - £20. Both operate by creating a vacuum in the chamber which sucks the oil out of the engine sump. I have used both and would stongly suggest your getting the more expensive, cylindrical type. The reason is that in that model the vacuum is created on the downstroke of the pump which makes pumping very much easier than on the spherical version on which you have to pull up whilst holding the device down - quite tiring, I've found. Take it from me, it is well worth the extra expense. The pouring of the oil from the chamber into another container is easier on the more expensive type, I have found. One tip, run the engine first to heat the oil - it then flows very much easier.

ps the cylindrical type comes with two 'dip-stick' hole tubes, each of a different diameter - obviously choose the larger one if possible.

The Pela round one does up to 6 litres.You can get it on the web for circa £30.If you have the engine oil warm enough(I run mine for about 15/20 mins) it works a treat.

 

[boy boater]

The two types I describe above both have 6 litre capacities.

12v one with a replacement sump plug, gets all the settled crud out

They do - but lots of other modern marine diesel engines have this facility as well. Nanni, Vetus, etc etc. Its seems to be all the rage to have a built in sump pump.

In answer to the OP, I have just bought a Pela and am very happy with it. Its better than the old manual vacuum pump that I had. The pipe-work is better quality (which isn't saying much) and its not very messy. Vic is right - you do need to warm the oil up first.
