I haven't had to do this myself but someone posted this recently as a potential solution to your problem.Will using a stainless steel helicoil into the aluminium engine cause galvanic corrosion?
My sump plug threads are stripped and having been held in with locktite for the last year it is slowly leaking oil and time for a service, are heliocoils a recomended solution?
Thanks,

Never used them but don't they mean you have to remove a lot more material to fit them? So long as your square never had a problem with helicoils but I do feel like what I imagine a bomb disposal expert to feels like when I "go for it" lolI hate Helicoils: if you don't get it perfect the coil misses a thread and you end up with an almighty mess.
My preference by far is to go the Timesert route. Easier to use and utterly bombproof once in. Much stronger than the original thread. More money (although you could probably sell the kit on after use as they come with a number of inserts usually) but a very high quality repair.
Hi. In which phase of the work in helicoiling do you se the biggest risk for problem, I didnt follow fully?I hate Helicoils: if you don't get it perfect the coil misses a thread and you end up with an almighty mess.

Why not drill and tap the next size up instead of using a helicoil?Will using a stainless steel helicoil into the aluminium engine cause galvanic corrosion?

I done this repair 3 weeks ago using that set. It worked fine for me.The Thread repair kit shown does that
Interesting. I might look into this. Which extractor do you use?I would also consider using an extractor pump through the dipstick hole for oil changes from now on - I do this and the whole job is done in half an hour of leisurely working without the bother of having to raise the car to remove the undertray and wait for the sump to drain etc.
I have experimented and only a small dribble of oil is left in the sump if you do then remove the plug - the additional advantage is you can use the hose end to suck all the oil from the filter housing too so it’s an excellent all-round option - I change it every 7500 miles.
No, my 30 odd year old Golf had them fitted at the factory.Will using a stainless steel helicoil into the aluminium engine cause galvanic corrosion?
