ENGINE OIL REPLACEMENT
by vwt4 Tue Jan 08, 2013 2:56 pm
Hi all
I have been thinking about replacing the engine oil on my VW T4 but have heard that the sump plug is difficult to access and if damaged can a pain to replace, has anyone any ideas of how to do this easily I have thought about suction via the dipstick tube, any other ideas would be good
thanks

Hi Mike,
This was the one I bought ....
[You must be registered and logged in to see this link.]
There are cheaper ones on Ebay, but I think this is better quality !!
I have used 12volt versions before, but to be honest, too much faffing about with extra waste-oil containers,
Good luck,
Brian

It might be worth just seeing if you really have a problem or not. You will see from the link posted earlier in this thread my suggestion. Having had a number of T4s not all had this problem. When they did, having fitted a new plug (and made sure everything was clean prior to fitting), the problem went away. IMO it is better to let the oil drain out in the normal way.

Using a suction pump will pull all the bits of swarf back up through the engine.

Surely the suction pump pipe goes into the dipstick tube which goes directly into the sump?
You would just be sucking the oil up the dipstick tube?

Hi All,
Most (if not all) small boats have to use the suction method, so I am very satisfied (and my back is a lot happier
) using this method ....... incidentally, I change 'Clubby's' oil very frequently 
....... as I have said before, "Oil is cheap ..... Engines are expensive"

I've had several VW group cars, 3 Skodas and a VW Passat and I used to use (until he emigrated) a specialist VW mechanic, VW trained at major dealer and he always used the suction method so maybe it's the way VW dealers do it anyway.

Hi there,
The sump plug on the boat was impossible to use without spilling all of the oil into the bilges.
When I bought the boat it had one of these in the Tool-box.
[You must be registered and logged in to see this link.]
I mentioned to my brother that it was a real pain because the access was so tight and I kept scraping my knuckles; so he phoned Santa and this appeared the next Xmas.
[You must be registered and logged in to see this link.]
As a method for changing the oil and whether or not it does a good job all I can say is that the engine was over 30 years old, had over 6,000 running hours on the clock and "through the dipstick hole" was the only way in which it could be drained.
Hope this helps.
Best regards,

Hi
thanks to you all for your replies, having had a look underneath and the clearance and not having ramps or a pit I think the suction method is what I will try mike vw74

I have one of the Mannesmann Scavenge Pumps which I've used twice with very variable results. For a start it seems like the height from the base of the sump to the top of the dipstick tube is on the limit of the vacuum that it can produce and, frankly, getting any oil out has been a long, slow process. Also once air has got into the pipe, it's extremely reluctant to self-prime again and start pumping. The engine oil also, according to the instructions, has to to be warm but not hot for the pump to work. I ended-up taking the cover off the pump: it appears to be a geared rotary vane type, but the vanes are held against the housing by centrifugal force only. Therefore I suspect that the vanes are not making appropriate contact. Despite the low purchase price, I thought being German designed etc it would be good kit. Not so, and I wouldn't recommend it.

Hi there,
I always warmed up the engine first then placed the pump in the bilges so that the syphon effect would help the flow to the pump.
Six years, six oil changes and no problems. I ran clean oil through the pump after I had finished each pump-out and then blocked the suction and discharge with kitchen paper to keep the toolbox clean.
I can only presume that you may have got a "Monday morning" pump.
An alternative reason is if the pump was ever asked to pump cold oil. In this situation it is possible to over-pressure the discharge side of the pump. The neoprene vanes then deform and reduce the pumping capacity.
There are alternative makes available.
Best regards,
Ian
