smell

[aniforos]

I have a 77 Westy that I have recently done some work on. I have had the engine and trans out so I could put another trans in it. While the engine was out, I changes a lot of exteriour stuff.....cables, clutch, seals, foam engine seal,etc. I replaced the engine without putting in the accordian heater tubes which connect the heater control box to the body of the vehicle. I plan on buying new ones as my old ones were in pretty bad shape. I have driven the bus some without the old ones in it and I have a gas/exhaust smell inside the bus. Is there a chance that the engine fumes can still be sucked up into the body tubes and into the bus? Thanks for any comments.

YES i believe fumes do enter the cab through the open tubes, last summer i fitted j-pipes instead of heat exchanges and left the tubes open, i had also just completed a lot of work to the engine so it was extra smelly! I blanked the open tubes with gaffa tape till i got my new exchangers and when i fitted them i realy made sure all the seals were good and tight - on a long journey those fumes could be dangerous!

It's what you can't smell that kills you.
Carbon Monoxide is odorless! Thats why it kills people in cases of homes too airtight and with faulty heaters....
Tennis balls and some duct tape will keep it blocked off....
