Rusty petrol cap

[Steve Brookes]

Just wondered if anyone else gets corrosion on their petrol cap? It was getting so bad on mine that I was concerned about it flaking off and getting in the tank. So I gave it a good polish up with a dremmel (wire brush and then fine emery disc).

You have obviously lost the protected chemical ( anodised etc ) coating on the inside of the cap so by dremeling the rust off it will come back even more as there is nothing there to stop the bare metal rusting. Painting it will also possibly cause the paint to flack off into the tank due to the close nature of the petrol and the environment the cap would be expect to work in.

Best bet is buy a new one ..if it has no lock its a few pounds from OPC (Coupe's have no locking cap by default), locked caps with stipulated keys (Cabriolets ) cost a little more and have to be special ordered to match the key set.

993.201.271.00 no lock
964.201.906.00 Keyed but no stipulated lock number
964.201.906.01 Keyed but with a stipulated lock number to match doors etc

I clean mine with white spirit,then coat it with Vaseline(the fuel cap,that is) now & again.

You're right Ian, it will definitely come back. I've seen new ones on ebay for £28 but will check out the OPC prices first. I was interested to see how many others have this issue - obviously Vitesse has it too.

Mine does this as well.

Basically cleaned up and bought a new rubber seal for the cap. Seemed to help but it will rust again sometime.

Gentlemen, can you not get the red plastic variety ?

The cap is red plastic but the screw plug side is metal. Is it all plastic on a 993?

Mine was rusting too,bought a shiny new one from an OPC,can't remember how much but wasn't alot or i would remember,nice and shiny,no lock makes it cheaper i think the cover works with the central locking unlike a 944.

Ah! Perhaps I misunderstood. My cap head is plastic but the screw thread is anodised alloy which appears corrosion-proof.

Its red top with a metal thread ..that is anodised etc

I think and anodised cap after 15 years or so will go - I would just buy another one! In fact 2 years ago - I did.

Steve,
Mines exaclty the same. Thought the same as some have suggested and buy a new one, just not got around to it and then there's always something more expensive to spend your hard earned cash on !! []

We'd best get straight down to the OPC because it looks like there's going to be a rush on these

Who can see once it's screwed in?In my opinion,it's a thin steel section with a rolled or pressed thread either made from precoated steel or zinc plated & passivated after manufacture.
Just use vaseline now & again.[]
