I recently noticed that when I park on an incline, the car slowly creeps down the incline when the motor is off and in gear, in either 1st. or reverse. Even if it's only a few degrees of incline, I have to engage the emergency brake to stop the creep.

I don't notice clutch slippage while driving - even when in 6th gear, throttling up.

Not sure what's causing the creep ... any ideas?

You should always use your parking brake every time you park the car.. period... the motor/tranny is not a parking brake... use both and if the e brake is functional it shouldn’t move if your in 1 or R... think of it this way, you can bump start a manual car, so yes it will roll or could... if you have a bad clutch you’ll know it....

What he said. You should NEVER park a manual transmission car without engaging the parking brake. Without the brake, you're relying solely on engine compression and rotation/accessory drag to hold the car in place. Bad idea.

It's also no way to test for a slipping clutch.

low compression won’t attribute to a car rolling easier...
Yes it could... I have experienced it but not in my Porsche and the incline was decent, but it can happen.
