Did you replace any other parts like the master, clutch line, or slave - or are all those components still original?

When I installed my clutch/flywheel, I had to adjust the push rod on the MC and the clevis. I did upgrade the MC. I believe it is recommended to upgrade the MC if you're putting in a stronger clutch, but not always necessary.

Maybe try bleeding it again before throwing more parts at it?

 

All those parts are still original I believe not sure if the previous owner did anything with them. I will try bleeding it asap and let you know

 

Curious to see if you resolved this issue. My clutch pedal started doing exactly the same thing today.
