DIESEL / Re: Draining engine oil with a vacuum pump

« Last post by Dazzler 40 minutes ago »

I recall some time ago that there was a lengthy discussion on this subject which I followed with interest as I was contemplating doing the same thing for intermediate oil changes.  It must be OK at some level as boat owners have no choice really, other than lift the engine out for every oil change.  On balance I would always prefer to run the engine till it is hot then drop the sump plug and leave it draining for a good while.  My two cents.

first person with any common sense  all the bs above explains why we warm the motor to thin the oil and why there is a sump plug with a magnet so all sluge and metal is quickly removed.

ADVICE FOR POTENTIAL BUYERS / Re: Would you upgrade?

« Last post by Dazzler 47 minutes ago »

Hi Vanessa,

If yours is a PD it is the current model. Most of the latest changes are only cosmetic. Nothing wrong with what you have got.

You'll lose heaps unless you can get top dollar selling it privately which is extremely difficult.  They'll only we take fgive safety you what they think they can sell it leow.sor granted ns $3000 or measure and less any allowance for things like new tyres, rego, cleaning etc.. depending on what your car needs to be saleable.

Safety features are nice, but most of us have survived a long time despite being carted to school without seatbelts and other life protection systems.

ADVICE FOR POTENTIAL BUYERS / Would you upgrade?

« Last post by Pikapolonica 2 hours ago »

I bought my i30 in 2017 and not long after I did purchase, the newer model came out with the bells and whistles with the safety pack (at the time I did ask the dealer if a new model was due and they flat out said no).

Anywho, car under finance and still have a considerable amount owing.

Just curious...............would you upgrade to the newer model of i30?

I've done about 55,000km.

... all the bs above

A totally unwarranted remark.

DIESEL / Re: I30 handbrake issue.

« Last post by Fresh_I30CW_Owner 4 hours ago »

I've got the same issue as you describe.
my left rear wheel is still able to be turned by hand (not freely, but not a major resistance) , even when I pull the handbrake lever all the way up.

After diagnosis, it was indeed the lever, to which the handbrake cable attaches to, which kept being stuck.
I tried to free it up, but it didn't do much, so I ordered some new brake shoes (for the parking brake) and I'll put them on next weekend and clean up the lever.

If you need some pictures on how to get it loose, I'll post them here for you

The pipes/hoses on my two vacuum pumps are quite hard plastic. They will bend, but they are not like rubber hoses. They are so stiff that they will go down the dipstick pipe and stop when they hit the oil pan. I usually lift it couple of centimeters up from the bottom as the oil comes up so much faster when the tip is not touching the bottom of the oil pan. After it starts to such air, I pump more vacuum and push it to the bottom to get everything out.

Most important thing is to change the oil with warm engine if pumps/vacuum is used. Hot oil comes out so much better. The pipes are so small that the viscocity of the oil slows it down.

One thing that people often talk is that suction method is not as effective as draining from the pan. Often they say that sludge is being left to the bottom of the pan if you only suck the oil out. I do not know which way is better. Suction is just so much easier and faster that I prefer it. If slugge forms in your oil, shouldn't it be catched by the oil filter? Or if sludge forms excessively, shouldn't you be changing your oil more frequently, or use better quality oil? Previous car I had, I changed the oil with vacuum pump for 100tkm. Never had an oil/lubrication based issue. Now with i30 I've used vacuum pump for 150tkm and never had oil based issues. I must admit that I change oil 2 times a year, every 10tkm. With vacuum I get 5 litres out of the i30 engine. Same amount that many members have reported with regular method oil change.

Doh!!

I just realised what an idiot I am. The dipstick tube has a bend, so obviously I can't push a straight hose around the bend. I can easily push the flexible plastic tube down all the way into the sump, although I cannot tell where the end of the tube is. If it bends back upwards then it will not drain down to the very bottom of the sump.

It's an electric pump. I did once use a friends Sealey extraction pump with a large round tank, but I found it took a long time and the inside of the tank was so dirty with old oil that it was hard to tell if anything was coming out.

The hose on that was like the outer tube of a bicycle brake cable, made from tightly coiled steel wire with a thin layer of plastic. When I tried to pull it out of the engine it became stuck and I had to tug it quite hard to pull it out. There was a tear in the plastic coating and my friend then complained it made it useless because air would leak in through the tear. I repaired it with a sleeve of heatshrink tubing.

I have also bought a 6mm diameter aluminium tube which I was going to attach to the plastic tube and push down the dipstick tube. Then I would know if it is touching the bottom of the sump pan. When I tried it today I realised that it is too large to fit down the tube.

It would be interesting to know if you can get the hose right down into the sump on your GD
