My Westerly Storm is powered by a Volvo 2002.
The exhaust hose goes from the elbow downwards and does a 180 flat loop under the engine before running back to the water muffler/Trap. This loop lies flat in the bilge under the engine and at times lays in spilt diesel and bilge water.
Today I removed the pipe from the exhaust elbow and pulled it out, and indeed where it had been lying flat the pipe had degraded. As there was plenty of hose my thoughts were cut out the rotten bit, and connect it back, leaving a shorter hose that would not lie in the bilge of the engine bay.
With the elbow removed and greased, and the pipe heated I could not get it to go on all the way. It looked as if the inner lining was concertinering as I tried to pushed it on.
I have now removed the whole piece and decided to replace with new. My questions are;
Did this flat lying loop under the engine serve any purpose?
Once used does the inner lining of exhaust hose distort and become almost impossible to use again?
When pushing on the new hose can I twist the elbow down the pipe using the wire reinforcement as a thread?
Any tips will be gratefully received.
