Cutch Tube repairs, See lots of these done, but WHY needed Options

[barefoot]

There's a plethora of repairs done to fix broken away clutch tubes, but there should never be any thrust load on this tube. It's just a conduit to route the cable thru the tunnel area.
Only thing i can think of is if the cable sheath in the engine bay is a little too long, then the fixing at the tranny bracket that also holds the pully to rotate the cable 180 Degrees is not adequately fixing the aft end of the sheath, then the thrust load pushes on the end of the clutch tube where it exits the firewall.
I'm getting the the point of re-installing the engine and then can check if the sheath is loading against the tube and not the aft end fixing.
Anyone been thru this already to help with this mystery ??

You have to clean the tunnel out to check everything. I would as a precaution and weld a D shaped washer around tube on rear firewall if you are seeing flex. Never worry about torn out tube.

D shaped washer is nothing more than a correct hole size washer ground off on one side for the flat side of the floor pan.
