Sump plug stripped thread?

[Dry Rot]

I gather this is not an unusual thing to happen with an aluminium oil pan, even with careful use. The steel plug just welds itself to the aluminium and the weakest part breaks when it's time for an oil change.

But what do TFFers recommend as a fix? My Landrover has been in the garage for three days now and I'm frightened to ask them!

There will be an answer on a Landy forum.

Get another sump . plenty around

Cocoon it with thread tape and stick it back in, that’s what I did with my Astravan 80000 miles ago !.

Well, that's an interesting bodge! One suggestion was to get a bolt the same size and thread as the drain plug and cut it a bit longer than the plug. The theory being that there should be some thread remaining which was not in contact with the steel plug.

But I'm too much of a wimp to try either!

BODGE !!!!

I prefer the term permanent fix

I am sure there are thread replacements you can drill out, tap oversize and put the replacement thread in , helicoil I think they used to be called.

Common thing for garages to deal with - local guy fitted helicoil and new sump plug for not a lot of money - he had a kit similar to the previous post

Would there be enough meat left round it to drill out and tap a size or two bigger. Not necessarily, but maybe then fibre washer under shoulder.

Don't worry about it, there's oil under EVERY Landrover.

You know what they say.. "if there's no oil UNDER it then there's no oil IN it"

Andy at Precision Engineering Services in Inverness will stick a helicoil in for you. If not, give Hamish a shout at Inv 4x4 and see if he has a spare sump.

Yes, I know there are several solutions, just curious about which is the best one. The garage phoned this evening to say they'd done the job, so the question is academic now.

I think it's a 2.5 engine, done 100,000 miles and no drips. It hardly uses any oil and I'd like to keep it that way. Bought it off some non-mechanical bureaucrat with a horrendous vibration. Finally tracked that down to castellated tyres caused by worn shocks. Other silly things were easily sorted and it's a damned good vehicle now.

Used to do this with Mini sumps when the same thing happened, even had a source for oversize plugs.
