I was cleaning the Forester engine using the Subaru upper engine cleaner this morning. I was worrying that the tiny hose that comes off the can might disappear or gone inside the engine via the vacuum hose. When I finished spraying the last bit, tool the can out then....
I realised the tiny hose disappeared!
Looked everywhere and still couldn't find it.
So I took the vacuum box our trying to find if ut was at the vacuum hose entry or not but it's not there!
What would happen if that tiny hose gone into the engine via that vacuum cleaner hose entrance???
 
Oh bugger! I'm not sure on this one. Was it the brake booster hose that was removed from the manifold? Or the hose near the throttle body?
 
As a guess only. My musings are I suspect that the offending tube is plastic and would be chomped up by any metallic moving parts. Also being long and thin it may not move too far if inside the induction system despite being in a "windy" area. My guess is that if it didn`t get chomped up it may also melt. Either way not a desirable outcome however being a lot softer than any metallic component it probably would not cause significant damage. If it wound up inside the combustion chamber, most unlikely, it would be burnt up as fuel. May cause a misfire or an ECU fault display.
How to determine where it is would be difficult without induction manifold removal.
As the Subaru engine bay is a wonderful system of hiding places it may well have fallen down and is well hidden still somewhere. Can only hope you find it there without pulling everything apart.

Yes ateday, the engine is still running (apparently ok), hopefully, worst come to worst, got some more "fix" for the old head gasket. :ROFLMAO:
I only hope that it will last till the kids finish learning their driving...
