That is true, but the chances of them rusting is also less, you could use hamerite or similar on them, it's just easier to apply a coat of grease or waxoyl, no real prep required.
OK, planning on getting to this tomorrow as a Father’s Day activity :D. Really hope I don’t find any signs of leaks to stall my visit to Brands on Tuesday [-o<. But, better the devil you know.

Sorry to hear you have had a problem Rod, Mazda obviously never learnt from the S1 when even the free recall pipes went just as rotten, just as fast as the ones they replaced. This is the third R3 failure I have heard of in as many weeks. Wow our roads must be soooo bad as Racing Beat recon we are the only people who by the R3 version!!

One of the reasons that Japanese cars suffer so much from corrosion (remember Datsun?) is that in Japan they don't put salt on the roads.

I was in a meeting in Germany between Mazda, Ford, Volvo and JLR engineers, focused on corrosion protection.

The Japanese still didn't really believe how corrosive road salt is compared to just being near the sea - which is their "equivalent".
They have artificially accelerated test facilities but still didn't understand that the real world can be nearly as bad.

The arguments were going in circles with the Mazda guys arguing that the European manufacturers should be putting their efforts into lobbying governments to ban salt on the road, fixing the issue at source.

They were taken outside and shown a Fiesta and Mazda 121, both built side-by-side in Dagenham, with hardly any rust after 3 years, and a Mazda 2(?), built in Japan that was only 18 months old and already suffering.

Modern road salts even include additives to help it cling to surfaces, so it doesn't get blown or washed away, which also makes it stick under the cars.

Some conspiracy theorists believe that this is part of a plan to keep turnover within the auto industry, not just to make profits for the manufacturers but because most western economies rely on it...

Mine failed on the drivers side connector on the line that connects the two radiators together.
Good to know, thanks :thumleft:. Out of interest, what (if anything) needs to be removed to get a clear view of this failure point?
I didn’t do it, Aston did. I would expect the undertray would be the easiest way to check them all. Otherwise possibly the wheel arch access panel

I‘ve heard that airport runway salt/de-icer is incredibly corrosive. It would appear that the better the de-icer is at melting ice, the worse it is for non-galvanised machinery :?.

Very interesting to hear the Japanese POV on this. I understand that mainland Japan use a combination of heated roads and chemicals rather than salt, and ice/snow isn’t cleared from roads across a lot of the country - drivers either buy winter tyres/studs/chains, or don’t go out.

I was contemplating an imported NA MX-5/Eunos before settling on the RX-8 and read on the UK owner’s forum that salt is actually used on the Japanese island of Hokkaido. As such, no imports (should) come from there. If that is true, it’s strange that Mazda still bury their head in the sand on the corrosion matter.

Personally I think the biggest issue is the way the plastic surounds the pipes, meaning the pipes cant dry out as there's no air flow around them plus the moisture stays around, killing the pipes.

I got a good look at the easily accessible points on my oil cooler lines today. Some corrosion, but fortunately no signs of any leaks to date or drips when running. Good news for what’s looking like it’ll be a 30 degree track day this week!

30EA7503-2C01-4EC0-8908-B4C44B9DA505.jpeg
Interestingly, the lower driver’s side line under the wheel arch was most corroded. I would have thought that the passenger side would have had a rougher time, due to getting sprayed in more puddles and crap at the side of the road.

I did, however, pull out about half a flower pot’s worth of soil from behind the driver’s side side skirt and in the holes behind the back of the front wing, so perhaps that had something to do with it :shock:.

As suggested, I caked the problem areas in some Castrol automotive grease, gentling rubbing off the surface rust flakes from the most corroded line in the process.

Based on these pictures, does anyone care to take an informed guess as to how long I’ve got until I really need to be replacing my lines? Further corrosion should be kept at bay. My RX-8 is parked in a garage and will rarely see another wet road in my ownership, doing perhaps 5k miles a year.

You should be good for a few years at least, it's interesting to see that the ferrules at the end of the hoses seem worse than the metal sections of pipe, on mine it was the metal section of pipe that was failing

This is good news indeed, thanks for the the steer and comparison pic Paul :thumright:.

Very strange to see the differing points of corrosion. It’s almost like every third component is a duff one. Either that, or there’s a differing level and point of exposure to the elements due to piping and arch liner fitment variations :-k.

I found that the pipe itself was where the corrosion proved terminal. Seems to often be worst under the protective rubber sleeve, under the bracket.
The connector seemed to be ok..

Don't lose those little circlip type clips, Mazda don't sell them separately! I'm sure it could hardly be described as impossible to make something up if needs be, but they are kinda important.. :D

I’m reading this and Clive’s post and wondering whether I should have tried to peel back the plastic/rubber sleeves to see the metal pipes beneath them :-k. These didn’t seem to be removable when I looked, at least not without dismantling the lines.

It was relatively easy to remove the little bracket, and once that's off you can move the sleeves easily enough. Thinking about it again, it wasn't under the sleeve that was the worst part, but still worth checking I guess.

Got it, thanks for the clarification John :thumleft:. I won't worry about it too much then, but will have a look next time I have the wheel arch liner off.

I've got a Racing Beat kit waiting to go on mine, £600 for the R3 version. Although its looking like there no use to me with my new engine set up. Don't know if that's a good thing or bad thing, lol.
