Stainless Exhausts

maybe only a very few short journeys?

I'm told the secret is longer journeys so that the engine/exhaust warms up?

Rob graham ("Rob graham" ) gurgled happily, sounding much like they were saying:

Really? When was that?

Duration of warranty, absolutely - three months was common on new cars in the early '70s, but it was parts and labour.

I always buy new cars. Why should I sudsidise subsequent owners?

Aye well, if you change the car every time the ashtrays are full....

Best wishes all, Dave.

Sensible legislation? Do we still do that sort of thing?

Best wishes all, Dave.

Silk (Silk ) gurgled happily, sounding much like they were saying:

You already do...

Unless, of course, none of your cars survive to be sold used?

Or perhaps when the exhaust starts to get a bit noisy?

I can't remember the dates when these things happened but I know my father's cars, bought in the 50s, only had parts warranties.

I believe that's right. Most of the corrosion takes place on the inside, due to the corrosive nature of the exhaust gases, although this is said to be less prominent in the case of diesel engines due to the more oily nature of their exhaust - but I don't know if this makes much difference. Anybody know the answer?

Best wishes all, Dave.

Well said, Rob.

We already have too much 'wisdom' being dispensed from on high - and most of it turns out to be crap....for which we pay....heavily!

Best wishes all, Dave.

Coo, it must be nice to be a wealthy layabout - or something.

Best wishes all, Dave.

No, I'm sure he's not *such* a bad driver - but I'm sure they are well used - as in flogged to death by a tearsarse. LOL

Best wishes all, Dave.

I only have to worry about the next owner. An exhaust failure will be much further down the line.

Silk (Silk ) gurgled happily, sounding much like they were saying:

My cars usually go at around the 100,000 mile mark. That's mostly motorway miles driven by an Advanced driver, so no worries there. In fact, how does a top of the range Skoda Octavia automatic, 2 years old, non-smoker, excellent condition, 100,000 miles for £8K sound?

Silk (Silk ) gurgled happily, sounding much like they were saying:

Tedious.

About half of the exhaust gas is water (vapour). When the exhaust is nice and hot, the water vapour reaches the end of the pipe and departs as vapour. When the exhaust pipe is still cold the vapour condenses before it reaches the end of the pipe. That is why exhausts rust more towards the outlet than closer to the engine.

My 8 year old Panda had done 60k when I got rid of it and (I think) had the original exhaust. I'd certainly not replaced it in the three years that I'd had it and it didn't look new when I bought the car. My 6 year old AX had done 63k when I got rid of it and had the original exhaust. The Ka was too new to have needed an exhaust and my Mk1 Octavia had done 83k in 3 years on it's original with no sign of problems.

I did have to get a new exhaust for my Grandad's micra before I sold it but that had only done about 30k in 9 years

The gases are there hot or cold. IMO the problem is condensation, which corrodes the system from the inside. The exhaust system never heats up enough to dry out on short journeys.

although this

Maybe, but I still think condensation is the problem rather than oily emissions. I wouldn't have thought a diesel running properly should be any more likely to spew oil out of the exhaust, than a petrol. Mike.
