I have a glass Shell oil canister on the firewall of my A. It is plumbed into the intake manifold. I can't seem to find any info out there on it. My question is what is it for and do I need it?
I’m thinking someone used it for a vacuum storage tank for a vacuum wipe wipe motor.That would keep the wipers going when under heavy engine loads and the vacuum normally drops off.Dont need it in my opinion. Dennis
Well I didn’t read your post close enough the first time and thought it was a metal canister.Maybe it’s some sort of water injector to help remove carbo from the combustion chambers.Just a guess.
If the pipe connecting it to the manifold has a valve in it, I'm guessing it was for an automatic feed for upper cylinder lubricant direct into the manifold. It was quite a common thing for years.
I would be tempted to put some Marvel Mystery Oil in the jar and see what happens to how the car runs...There were lots of these systems made...this sounds like a home made one...might work nice! Many of us do run Marvel Mystery Oil one way or another. Ernie in Arizona
