997 C4S Future Proofing

We usually talk about future proofing a 997's engine. Over and above getting a low temp thermostat (check), having an 06 MY IMS (check), frequently changing oil and using the right thickness (check) and being gentle with a cold engine (check), there isn't much more I can do (apart from a rebuild). Mine was 'scoped at purchase and had the all clear – so I'm happy.

Let's talk about structural bodywork then.

Given how many rusted and corroded 911s I saw before I bought mine, I thought it prudent to have a look underneath to see how things looked.

Off to Classic Heroes it went for an inspection on the ramp.

I'm happy to say that things looked very good indeed, but that didn't mean it was perfect. Small areas of surface corrosion were starting to form in places such as the front and rear chassis legs, in between the wheel arches and wheel housings and at some of the spot welds, etc.

I was advised that this was nothing to worry about, but that if left untreated could become a problem in just a few years time.

Thus, the plan was to remove the plastic, clean everything up underneath and address the rusty bits with chemical rust neutraliser, bring the parts that needed to back to bare metal and treat accordingly, apply anti stone chip product, treat with clear cavity wax and treat all alloy suspension components, nuts and bold with Tectyl ML.

Below are some pictures.

There's also a video walkthrough right here: https://vimeo.com/385281858

All in all I'm glad I had it done. It's what DeMort calls the 'waxoil service' ;-)

I'm also really happy with the job Classic Heroes did https://www.classicheroes.co.uk/

Sometimes you have to see your fair share of ***** cars to pledge that your own will never, ever look like that.

Thanks for posting those pics and video Jack. Certainly food for thought on maintaining a great car to a decent level for as long as possible. Interesting to see the relatively small amount of corrosion just starting to manifest itself and nipped in the bud. Costwise it surely must make sense if you can to take these
steps particularly if you plan to keep the car long term. Some nice Beemers too!
 
Good work, well done, do you fancy doing mine ....it looks like lots of work.

I will try to do mine ....
 
That's a great service and looks exactly like what I am looking for.

I've been thinking of doing similar myself to my 50K mile 05 C2S but I think I'd need access to a ramp & steam cleaner.

Maybe I could PM you to enquire about the anticipated costs?
 
Sure thing diceman. Just send me a message.

I'm not sure I'd go about doing it myself as it took very many hours of work to do it properly.

But certainly worth doing as there's no better maintenance than preventive maintenance where it's a known quantity.

My 49,000 C4S was £3k to have done
 
Mine was less than that, but every car is different and will need more or less doing depending on condition and who does it/where you have it done.

Consider how much it would cost to 'restore' if the corrosion really gets hold further down the line and it could be a bargain :D
