Thread: New Sump Plug, Do we really need one.

D3 had a steel bottom sump. D4 went to an alloy bottom sump ( sump it two piece - top and bottom). The D3 metal sumps were known to corrode in the mother country. Not sure about in Aus. Yes common practice to replace the sump plug but I have no idea why. A new copper washer etc seems logical at most. Another way to gouge you at service presumably. I’ve never replaced one and never had one strip or leak 🤷*♂️

If it’s the same as the 2.7D sump plug the Ford dealer sells them.

I replace the oring not the plug which is very expensive for some reason.

Ive reused them a few times on RRS and Puma (plugs are the same) without leaking

I was thinking about machining a substitute plug to take std o rings
Another thought was fumoto sump plug. Good on the RRS with underbody protection plate but is probably too exposed on the puma. You fit the fumoto once and then operate the locked valve

I assume the plug is metric something x 1.5 pitch. You can get new ones for a pittance from places like Tony Powell's or IFS complete wit o-ring. What do LR dealers charge for one?

I have used the same plug 5 times and there have been no issues - no leaks nuffin. I can see that it might be wise to replace it if it has been over torqued but other than that no.

I posted the above in Feb 2014 and am still using the same plug and O ring.

I’ve never undone mine. Always gone the suction route. Saying that, mine leaks oil from so many other places, not sure why I change the oil and don’t simply just top it up to refill it lol

Not sure if they have one to suit you car but probably they do. We don't do too much off-roading so it won't get knocked about but if we were doing serious off-roading then I'd stick with the sump plug.

Replaced my sump plug with a Stalhbus valve. Cut a 40mm hole in the bash plate. Quick and easy now. Well easy if you are old school and like crawling around under the vehicle. No fancy oil extraction pumps for me.

As the indy said to me when I bought ours "It's not leaking, it's just marking its territory".
