Technical What’s this on my spark plug?

[Mefster]

Just finished servicing our 121k 4x4 TwinAir, as no service history ()

Oil, filters and plugs done. Everything pretty clean so hopefully it’s been looked after.

Plugs were a bit of a struggle… finally manage after some penetrating oil applied. One of the plugs had a little rubber collar around the end. Nothing appeared to have detached from the coil packs. Reassembled and running fine.

I’m guessing it’s a rubber insert from a previous plug socket. Thought I’d better check it’s not a critical component unique to the TA engine!

Yes looks like the rubber insert on some plug sockets to hold the plug when fitting.

Eh up,

Yup some idiot left a collar on ,

Just ensure you put a smear of coppervease on the threads and the correct torque settings ( think it’s circa 15nm ) someone will correct me .

Iridium plugs are best in the TA in my opinion

Thanks for that everyone. I’ve just nipped the plugs up to start- my plug wrench was at full extension with a t-handle- I’ve ordered a longer magnetic 3/8” socket so I can properly torque them.
On the subject of antiseaze: I’d read that modern plugs are designed not to have it applied- what is the consensus? (I’m also bearing in mind it was a struggle to remove the old plugs!)

Eh up

In my opinion- Bo88ocks ,

Just get a smear on and ignore the advice on modern plugs, just a sliver on the threads works a treat honest

I’ve done it since I had the TA and torque up to correct Nm

Make’s changing a doddle and no risk of snapped plugs

But everyone has their own opinions
