This is a very common problem, especially once the rubber gets an oil
film. The air flow meter has a slight taper there and tightening the
clamp just pulls the boot down. I cost the AFM with  high tack, let it
dry, and then install the boot over it. It will stay in place yet still
be removable when needed.

Subject: Air Intake Boot clamp/seal question

I have a 1984 Vanagon Camper.
My air intake boot keeps slipping off of the connection on the top that
leads to the air filter.
(I know, that's super technical)
I think the rubber has expanded over time due to heat perhaps? The boot
is new as of September and just recently started coming off after a
couple of long trips to the coast. This of course makes the van stall
out and not run, loss of vacuum I believe according to list archives.
It doesn't seem to help to just retighten the clamp.

Is there a way to add something that will create a seal between the
metal and the rubber, create something for the boot to grab onto as I
tighten the clamp?
I guess it wouldn't be a good idea to use an epoxy, as it does need to
come off for various repairs etc.

Being an older van, the engine tends to shake slightly and the boot
just keeps coming off.
Your thoughts are appreciated
