Clutch cable won't hold adjustment Options

[KELTY360]

I've had the car 7 years and usually have to adjust the cable about every 6 months to restore complete engagement and smooth shifting, most notably in first or reverse. Now, I can adjust as usual and it works fine, but only for a few miles when it won't fully disengage and becomes very difficult to get into first or reverse without grinding.

A new cable was installed 3 years ago and has worked fine til now. Is it just stretching out and needs replacement or could there be something more sinister going on?

I had the same problem on both of my 914s.

The first one kept needing adjustment until I noticed the clutch tube moving toward the interior of the car. The tube attachment at the firewall had rusted.

On the other 914, a few adjustments days apart preceded a big BANG when the clutch pedal when to the floor as the cable broke.

If the clutch tube is not rusted at the firewall, replace the cable before you drive it further.
