Would anyone know the diameter of the 300tdi's sump plug? I ran out of my stock of sump plug washers and stupidly forgot the diameter.
 
Next time get a dowty washer will last the lifetime of the car and never leak.

Dogs danglies is the correct answer!
Plus they dont leak, quick check at oil change time, is the rubber bit still proud of the metal bit? if so good to go again, Ive been using them for years.
 
As I'm getting a bit long in the tooth, and increasingly ****ed off with a sleeve full of hot oil (it's an age thing) I bought the easy drain kit off "Difflock" can't remember what they are actually called. Doddle to fit, next oil change just point the hose end into an old oil can and no mess straight into the can. Great I thought, then knocked the spill tray I'd put under the filter when spinning it off and flooded my hardstanding with dirty oil. :mad:
One day I'll get it all done right, honest.

Mostly I have done oil changes on cars and bikes with drain plugs close to the ground, easy to get a washing up bowl under and in position when the drain plug is on its last thread (sometimes means dropping the plug in the bowl or getting a sleeve full of oil). First time I did an oil change on the landy - plug about 18 inches off the floor and drain hole in a horizontal position at the back of the sump, discovered that 7 litres of oil likes to shoot out horizontally, straight over the bowl and onto the driveway.
 
Just for added mirth, try doing it on a windy day. It's actually possible to get it down your neck as you scrabble about trying to wave the bloody bowl all over the place. Oh how much fun we used to have.
Try putting the bowl on a concrete block or something, that works. then of course it gives you the opportunity of tipping the whole kit and caboodle over when you try to move the full bowl. It's at times like this that I wonder how such a bunch of amaturs (sp) manage to actually get anything done right.
 
Over the years I have managed to master the art of oil changes without making any mess at all........ until last week. I was changing an oil filter on a 300tdi. A long time ago, I had cut and trimmed an old oil can into the perfect shape to fit on top of the front diff, allowing me to drop the filter into it and let it drip while I get other things done. As I was slowly manoevering it out, I felt a sneeze coming. I tried to hold it to no avail so I sneezed.... violently. I dropped the oil can holding the old filter onto my chest and knocked the pan holding 7 litres of oil over with my elbow. The garage floor now needs to be repainted. I am not happy.
 
On my 200tdi engine rebuild (disco into Defender) I welded a bsp nipple into the sump then fitted a tap with a plug (incase the ball valve failed).
I use a hose tail and a short length of hose to drain into a drain pan.
Doing the filter still sucks though:rolleyes:

I did the same donkeys years ago. Makes draining the oil a pleasure. I still smile every time I do it, remembering the bad old days of oil up your arm and everywhere else too.
Filter still a pain though.
 
So what is the best?
The Quick Valve or the Dowty washer. Fight!!
I have just got to the point that after several drip free periods and having to retightening when the two drips (sump plug and blow back on bell housing) appear on the drive, I am afraid to go much tighter on the plug.

My 'Difflock Forum' drain plug never drips, even after 8 or 9 years service. Just looked them up again on there website and they are enormously expensive :eek:
 
Anything that sticks down is going to be the weak spot when off road, only takes one branch to get forced up and you are in real trouble.

We used to have the same drain set up on some donkey engines we looked after, good idea, but very slooooow to drain when oil cold.
 
I have a sump plug that takes a 19mm spanner, can anyone tell me what thread it is? I read there are two different
