Technical Sump gasket

[murdo316]

Hi all

I'm about to remove the sump from my 2017 TwinAir Cross as the thread has stripped on the sump plug hole, whoever did it up on the last service horsed the sump plug up and it it took some amount of force to remove..

Is the gasket for the sump liquid gasket does anyone know?

Cheers

I've never done a twin air so can't advise specifically on your question. However I've done many stripped plugs in alloy sumps and my "go to" would be a dedicated repair kit if all that's wrong with it is a damaged thread in the sump. Early on in my career it would have been a helicoil but now there are kits which include everything you might need Here's a general purpose one, but you can also get them for just one size considerably cheaper. https://www.ebay.co.uk/itm/33647355...+irAMDI38kmuy0XtV1CXlR+Q==|tkp:Bk9SR9qc9dXTZw

Check on e par on here.

Glued on steel sumps via sealant can be a real bugger to remove without distorting them. Be aware oil puck up pipe way be plastic....

Alloy or steel sump ?

Fantastic, a potential life saver!

When the hole has been re-tapped, what's the best way to avoid shavings in the sump, a good engine flush or?

Buy a tub of grease and coat the tap threads before you start. Turn the tap in by about just one turn at a time before unscrewing it and cleaning it off. Pretty much all the swarf will be contained by the grease. Recoat with grease and cut another turn's worth. Keep doing this until the new thread is cut. Be generous with the grease. It does use quite a bit of grease buy a tub of grease is pretty cheap in the grand scheme of things.

The earlier VAG ally dumps were common to do. They used quite a short plug. Later they introduced a longer plug which engaged more threads and it was much rarer to have stripped threads.

Edit I used to do an "early" oil change on my own or family and friends vehicles after doing this in the hope any bits I'd missed would be flushed out. Of course that's not practical with a customer vehicle and, as I never saw any problems with one's we'd done, I pretty much just stopped doing it. Never had any problems. Take care to start the tap nice and square on to the hole. If you cut it squint then it won't compress the sealing washer equally all round and you might get oil weeping.

Grand, standby for an update on how it turns out as I shall be in the garage (until late no doubt) one evening this week doing it.

I'll buy you a pint if ever our paths cross in town, I've a second baby due in less than two weeks and your advice has really gotten me out of a potential pinch.

All I need to do now is not balls it up when the kit arrives!

If you can get a suitable nut the correct size, pitch and thread, that may help you starting the tap off square...by that I mean starting the thread operation *in line and not wonky*...

Also treat yourself to a new copper washer and anneal it before use (or at least anneal the old one) this way it will seal without having to welly it up! (I know you didn't do it first time!)

Good advice. The kits I've used all came with new crush washers in the box.

Good luck with it. Just take it nice and slow and I'm sure you'll be just fine.

Many congratulations on the imminent arrival of your second child - Mk2 version you might say? We have three and it's true what they say - which is that once they outnumber you all is lost! .

Unfortunately I'm tee total, have been for years ever since my big tummy op. Made up for it when I was younger though! Who knows, maybe one day we will bump into each other, I'm in the north of the city not too far from the Leith area.
