How rusty?

[Leeshez]

These was taken out of my 182 with 33858 miles on the clock. The othere two are just as bad.

So much for the massive life they are meant to have - once a year change item for me !

Cheap Nasty reno parts

 

[Fletcher]

bloody hell they are rusty.

 

[DrR]

My 75k 6 year old ones in my 172 looked as good as the new ones!

 

[Guppy]

better change mine soon!

 

[fUbAr]

blimey... worth checking mine!

 

[Martin_172]

mine after 42k and 5yrs looked fine!

Check the HT lead boots are sealing properly. If they let water in then any water splashed about the engine bay will find its way into the plug holes and stay there. If you don't do many long journeys it could take a long time to evaporate off!

I replaced mine at about 70k and looked like new too!

Thats got to have had water down the wells at some point. Bay cleaning?

 

[GarethM]

ill be checking mine after seeing that!

 

[Tigger]

Bloody hell, what year was your car?

1 of mine was exactly like that when I had mine changed (Nov 03 172 + 28k miles) :dead:

 

[mattjk]

You have hosed the engine bay down and filled the wells with water

Quick wire wheel will make short work of that rust

 

[Tigger]

Any other likely causes for this?

 

[Gray]

After covering 65K mine looked brand new...

Looks to me like you have had water down the wells / left the car standing for long periods of time / and / or only used the car for short journeys?!?! (maybeee)

 

[Alastair.]

looks like somebody has jet washed ur engine at somepoint, water would have sat around the plug making it go rusty
