Air flow sensor boot removal help- CIS

[OldSpool87]

1982 SC: Any tricks to getting the boot on top of the CIS system off? I’ve loosened both clamps and can’t get the little beast to budge. I am trying to smoke test my system for suspected vacuum leaks and want to close of the intake completely to avoid losing smoke out to the air filter housing. I am supplying smoke through brake booster line for what it’s worth.

I’d appreciate any thoughts.

Thanks!!

Yep. Maybe a block of wood positioned smartly with the help of a screwdriver to pry.

So…eat my spinach and grow a pair. Strangely not the first time this advise had been given to me and worked.

Thanks for the feedback. BTW- these little paint can with mineral oil smoker jobbies work pretty well. I hooked it up to a 20oz CO2 tank.

Still a good idea to be sure than break a $$$ NLA part... not the case here.

Use a nylon spudge to get under the lip on each side and get it started. It will come off. You have to loosen the metal bands all the way or remove them. Getting it back on and lined up is a pain too. There's not a lot of room if you have a noise blanket in the engine bay.

yes, loosen the metal rings as much as possible, not just cracked loose.
and then i use a flatblade screwdriver to pop it off,
do not leverage it on your airbox!

I’ll get some pics of the rig in action hopefully this weekend. The whole set up looks rather diabolical and is definitely good for getting the “don’t even want to know look” from the wife.

Thanks fellas for the suggestions on prying up the boot. I have some trim tools that might be up for the job.

Much less force will be needed after a squirt or two of penetrating oil.

So…I never got it off. But, I sealed off the airbox where the filter sits with some plastic wrap and put some smoke through the brake booster line. I checked all injectors, airbox seam, intake boots, and anything else I could get my little inspection light on. The only remarkable smoke flow was seen coming from the space between the fuel distributor and the intake boot covering the air flow plate. There was also a little coming from the lid of the pop off valve (not glued joints). So, it may be time for a new popes hat in which case I need to hit the gym more to get this old one off.

When I did mine, it was "Take it easy" & slow.

After you remove the two clamps, use some type of
rubber or plastic wedge (like a rubber specula) to remove the boot while you
pull up on the boot, while squirting some wd-40 between the boot,
at both ends of the boot.

Let sit for a while, then try to rotate the boot loose.
