Getting gased

[zwhitea]

As its getting a little colder again, I have started to use the heater.. however this year I have started to get gased by exhaust fumes..? I assume this is a sure fire way of telling my the heat exchangers are knackered....

Am I right or do I have a different problem..?

Thanks for any suggestions in advance....

Adam.

If it really is exhaust you are smelling and not oil, then until you get the HEs welded or preferably replaced drive with the window open a little and the dash flaps open to, you don't want to nod off at the wheel!

Yes, its definitely exhaust gases and not oil.. Had the oil smell years ago, before getting the drain tubes which were leaking replaced...
Currently if I have the system on full and the window shut, you actually feel sick after just a couple of miles..!

Looks like its a H&S system for Xmas then....[8|]

Hi,
I have been following this thread with interest. Last year I removed all the exhaust system from my SC for servicing and looking at the exhaust pipes within the heat exchangers I came to the conclusion that the material used was a non corrodable metal i.e. non ferrous. The pipe work within the heat exchangers was as new and the date was inprinted into the heat exchanger casing my exchangers are original 1983. So I would take the exchangers off and test the condition of the pipe work within the heat exchangers for leaks. A test you could do is to blank off the exhaust outlet and fill the pipes with water and see what happens?, if the level falls then you have found the leak, if not then the exchangers are OK. Dont spend until you are sure where the leak is coming from.

Thanks for the advice... Will give it a go, providing I find the time.. Problem being I use the car regularly, and other than the custom backbox, the rest looks original... so I can see a lot of drilling required to get it all a part..[&:]

Hello,
You probably know all this but some tips for you.
When I removed my exhaust for servicing I dropped the whole system complete, all you need to do is undo the bolts holding the system to the heads i.e. 6 nuts and 6 socket head nuts and the 2 straps holding on the read muffler. I bought a special tool to undo the six socket head nuts from type911 for this job.(this tool was a good buy)
Once the system is on the floor I used a small grinder to gring off the rusted nuts and everything pulled apart. My 1983SC had a stainless steel cross over pipe but the connection pipe which slots into in on the passengers side was not and was difficult to extract. I used heat and a lot of twisting force to remove the old connection pipe. If you intend to reuse the original cross over pipe and need a connection pipe you will need to buy a Porsche pipe to fit which is very expensive( over £200 ), or if the cross over pipe is knackered then type911 will supply a crossover pipe with the correct connection pipe in steel at a competitive price, the connection pipe from type911 however will not fit your original porsche crossover pipe. I hope this all makes sence?
The only pipe I has to replace on my 1983 system was the presilencer I bought a Dansk pipe in mild steel from type911 (which I am happy with) with all the necessary gaskets and fixings to recondition the original pipes work.
Look at the type911 web site for a detailed layout of your system and components breakdown.
