Draining oil

[flybobbie]

When you remove oil filter there is a small o ring on plastic shaft.
Apparently this blocks a drain hole to sump.
Can a oil pump be used through this hole to drain engine oil, or is it not direct to sump.

Why would you want to do that?
Draining the oil when warm via the drain plug gives you the best 'drain' volume.
If you try to pump it out you will get oil left in the bottom of the sump that you cannot remove.

Also a good idea to flush the engine prior to draining, I use the FORTE engine flush..

True, but as i get older just a pain crawling under car, looking for a easier life.
Also warm engine probably melt the plastic pump out pipe.

I was told by an AA man "Dealers don't use the drain plug - they suck it out". Accessed from where, I don't know.

Dipstick pipe mainly.

I believe the complete lack of a dipstick is what generated the OPs question though.

I suppose we could simply ask a dealer how they do it?

 

[Nash3vans]

Oh ok

 

[bob4333]

Yes, dipsticks. Remember those?

What sort of an idiot thought it a good idea to delete them and replace them with electronics?

I spent 5 years in the industry in my early years and I have several good friends who are garage owners - engineers etc. Pumps are used to drain some items, differentials/gearboxes that dont have drain plugs. But I have never seen a 'run of the mill' wet sump car engine being pumped dry!
If anyone knows or has experienced differently I would be interested to know..

I don't think modern oils and engines get a lot of sediment like old oils used to but i did notice when i poured the old oil into a container the last cup full seemed like treackle. Mobil 1 oil.
I used the pump on my Berlingo diesel and made mistake of putting in The Range turbo diesel oil......don't.
It was way too heavy a oil and dragged the turbo, felt like the handbrake was on. I replaced with Mobil 1 i had to hand. Performance back to normal.

This was relating to a 9 month old Jaguar 3.0L XF estate in 2014. Just had it's 1st service and I was 180 miles from home when an "oil loss" message came up accompanied by the unmistakable smell of smoky oil. Pulled into a pub car park and summoned Jaguar Assistance.

Gave him my homespun theory that some fool hadn't tightened the drain plug correctly on the recent oil change. He listened politely then chipped in with most dealers suck the oil out and don't disturb the drain plug.

After a flatbed recovery, investigation showed there had been a batch of oil filters with a faulty "O" ring and the thing had split allowing oil to be pumped out under pressure. Fortunately I'd stopped quickly and the engine was OK.

There is an oil reservoir on the driver side at the front of the engine.

If you remove the cap whilst engine is cold,
(Don’t do it after a drive!)


There is a float, which acts similar to a dipstick.

The instructions are moulded into the plastic.

Is this an April Fool?
I was so taken aback I had to go and look at mine.
That is the cooling system expansion tank surely?
Don't go topping up your oil in there!

No, not oil in, but does that not show the level of the whole system?

You're a few months early with that one

If you do have any oil in there you might want to check the head gasket

What is in it then, coolant?

Ah, sorry it’s coolant!

I thought it was part of the oil system.

If you thought that was for the oil, where have you been checking the coolant? :?

Hope you're not putting the diesel in the wrong place. oke:

Still no worse than topping the water off by the black cap on top of the engine.
