New Sump Plug, Do we really need one.

Hi There,
They do make a Fumoto valve to suit the TDV6 engine, the only issue I had was getting the under engine protection back on. I ended up modifying the undercover plate with a plate / cap. I got a valve with the tube connection on it which is slightly longer than the other model of valve. The valve and under engine plate could then have gone back I suspect un modified. I think it would be good to cut a hole and install a small cover plate over the hole in the under engine plate so you don't have to remove the engine plate every time you want to change the oil.

Hi Grappler,
I've removed the old o-ring and replaced with a standard o-ring, in all honesty I didn't realise they were specially shaped O-rings. I have found a standard o-ring to be fine. Saying that if others decide to do this make sure it is a Viton o-ring not just a standard off the shelf Bunnings o-ring. If it isn't Viton or some other special hydrocarbon resistant ring it will swell, split and possibly dissolve resulting in a leak and possibly a loose sump plug.

Here is pic of the 2.7 TDV6 sump plug (its also he same as 2.2 puma)
Ive removed he o ring/ gasket for clarity

You can see it is a hybrid of an o ring and a dowty washer

The thread on the plug is M14-1.5

So, my take on the replacing of the sump plug is all to do with reuse of the washer than the plug itself.
Probably part of some EU rule to stop any oil drips on engines and stop DIY on engines , as with the banning of spin on oil filters (reduction of land fill) , and "lifetime" fluid in the auto (ditto).
I am sure some enterprising company will come up with a conventional plug and washer. Hey Mario, what about it? What a PITA to have to go to a dealer to just buy a sump plug when you want to change the oil.

So they are truly trying to make obsolescence more certain.

Whilst Viton is a good idea, the "Bunnings" NBR ones will be fine... They arent reactive to diesel...

You may be thinking of EPDM which is used in Brake systems... Its not a fan of Engine oil, hydraulic oil etc...

I have just ordered a Fumoto sump plug replacement F106 for RRS and F106N for Puma. The suffix n is a barbed spout for a tube. The Puma sump drains the oil at a weird angle and is messy so I chose the spout for that reason.

Will follow up when they are installed next oil change

Only issue I have with the Fumoto...

If the seal fails - you can unwittingly drive your engine to destruction...

The Stahlbus and similar have a sealed cap - even if the seal fails the oil can not escape...

Stahlbus looks nicer, thanks Tombie. The question is where to get in Australia?

Digging up an old one here, but what is the reference to an alloy sump? Mine's got a steel one... Why can't they just supply a new o-ring with the oil filter and chuck that one the old drain plug, I wonder if there's anywhere you can buy just the special o-ring?
