Engine cool-down time before draining the oil

I have used the cheap oil pump from aldi with the pipe down the dipstick and it compared well with the proper jabsco units
It is light years ahead of the Pela

How so?
Can't fault my Pela TBH, apart from being an old one with only one size of suction tube supplied.
I've sorted some alternative tubes for it, including one with a 1/4 turn valve which makes life easier when cleaning the bottom of diesel tanks.

It's very slow messy and bulky both to use and store apart from that it leaks
 
Re draining hot or cold, I once drained my Kubota 3 cyl l tractor engine oil immediately after the tractor had done a couple of hours of hard work. Yes, the hot oil was VERY hot but it drained very thoroughly. After I'd refilled and test run the engine the new oil was absolutely clean on the dipstick.
 
I have seen a tip for getting the oil out faster. A piece of 12mm plastic tube can be pushed over the dipstick tube and makes a good seal. You need to check if their is a small air bleed hole near the top of the tube and push the plastic past it. Connect the other end to the Pela. The problem with the Pela is that the bit that goes down the dipstick tube is just plastic covered curtain wire and has only about a 3mm bore.

I have not done this yet, but intend to when I go back to the boat.

Dipstick tubes rarely go to the bottom of the sump, they're often a press/hammer fit about 3/4" to 1" into the block.

Plus one, so check first that it goes all the way to the bottom. My VP MD22 has a dedicated pipe at the front that you take a plastic cap off and attach the Pela tube to. I sorted out a bit of cross over tube to suit. The VP 20x0 series has a similar pipe on the side that does the same trick.

D2-40, the 0 fell off!

Ah thats better.

Interesting because on that one the dipstick tube (#21) goes no distance at all inside the crankcase but some versions, if not all, have a pipe (#5) fitted to the oil pan to which an oil extractor pump can be attached.

I'm struggling to see how that would work - I get that the dipstick tube "SHOULD" act as the bottom bit of the pela ( just larger bore) but isn;t the rest of the oil system effectively sealed - so you will end up creating a partial vacumn that you then need to overcome? be brilliant if it worked though

No vacuum at all if you take the filler cap off!
 
Thought I should feedback here. Today I found a bit of pipe which fitted snugly over the dipstick hole and another bit which the pipe from the pela fitted snugly but fitted into the first bit of pipe with a bit too much wiggle room which I resolved with the aid of a jubilee clip. Connected it all and pumped (engine/oil cold). Oh then remembered to remove the other oil filler cap.

Wow! nearly 5 litres out in less than 10 minutes. Not only is that the quickest I've got the oil out that must be about the most I've extracted. *much* more effective than sticking the pipe down the dipstick hole. Many thanks once again.

Can't fault my Pela TBH,

My only criticism of the Pela (mine anyway) is that the pump is only a push fit onto it's spigot and doesn't lock positively into place.
I often want to use it one-handed, kneeling on the base and using my other hand to hold the suction tube somewhere remote, but the pump always pulls free as you try to work it.
 
Remember when refilling that the dip stick can be wrong. I blew up a landrover engine because the tube that holds the dipstick had got a knock and had gone deeper into the engine so that it read high. I changed the oil and was surprised that I had overfilled it so much. I then drained it out the bottom of the sump so that the dip stick read ok and when I was driving too fast up a hill the big end bearing went through the side of the sump! Fun times as I was late for a paediatric night shift on christmas eave but the man from the RAC kindly drove me to the hospital and then took care of the vehicle.
 
Numpty question of the week....

How long should I leave an engine (in this case a yanmar 3jh4e) to cool down before taking out the dipstick to drain the oil with a pela?.

Is this in preparation for the 'big push' or has the shorepower at Brighton failed again???:encouragement:

Big Push to actually move this boat somewhere...*anywhere*...before summer ends, yes. Now if only I could find the answer to my transmission oil question and find a strap wrench to get get the primary fuel filter off I'd be ready to...errr...well get the bottom pressure washed and change some anodes...

I'll look at your gearbox oil thread again but, in the meantime, if you have a screw-on filter which you intend to change and it's too tight and you don't have a strap wrench, you can just drive a sharp object / screwdriver right through the old filter and unscrew it that way. Not very pretty (and a strap wrench is actually a good tool to have on a boat for filters/strainers of all kinds), but I've resorted to brute force with filters once or twice over the years! The truth is that they should never be done up that tight but I've never met an auto or a marine mechanic who understands the concept of "just tight enough to do the job". :rolleyes:
