So having put new flappy valvey things on and new seals and new operating cables and bunged up the newly found holes under the R&R from whence hot air leaketh, I was expecting a veritable inferno of heat to come blasting out of my windscreen vents. Alas this was not the case, further destuction of the heating system revealed this at the front of the Bus. How the bloody hell has it melted like that? I mean, NO T2 has ever created THAT much heat that far away from the engine!
That's not rubber, it's hard plastic just melted into that shape. It fits perfectly so I thought it was original? It looks like hdpe tubing that you use for drains etc, completely inflexible at room temp. Are they metal on std buses?

Aha! Now that makes a lot more sense doesn't it? Further investigation has now revealed that a hairdryer creates sufficient heat to melt this tube. Makes you wonder why anyone would put a plastic tube in there, no wonder it melted.
Even better it's 3.5 inch. I can feel a raid on the engineering stores coming on, FFS don't tell the maintenance engineer!
