I am getting an occasional and very faint smell of propane from my '90 Westy
(130K miles). The valve is off and if the van weren't parked in the garage,
I probably wouldn't have noticed the smell. I opened the black plastic cover
(first time ever) over the regulator (?) and noticed a little oil dripping
from underneath it. Could this be where the smell is coming from? Is it
repairable?

Thanks for all information,
Jerry
