I've been around 911s for a lot of years, and never have I encountered this ...

97 Carrera 2, 78k miles, 6-speed, clutch (RS and LWF) has about 20k on it, shifts fine, no issues.

Pulled the car into my driveway today, which has a bit of a slope to it (going up toward the garage).

Shut the car off, but wanted to hear something on the radio, so I put the car into second, and didn't pull the emergency brake.

Hear a gentle groan from the front of the car, and the car moved backward a few inches, then stopped. Held for a few seconds, groaned again, and moved backward again.

This was repeated in third gear, as well.

Clutch issue? Something else? I don't think this is normal ... right?

When I drove manuals, I would either use first or reverse. Did you try any other gears?

+1 I would try that.

Always park in Reverse.

Why? My driveway has a slope to it too and I use 2nd for both the 993 and the '97 M3 and have never had a problem. I do however use the handbrake too.

+1 its the lowest ratio. 2nd, 3rd etc are higher. in 6th you can practically push the car

Just second and third today.

I've used second for 20 years now, and never had this happen before ... I didn't like the groaning sound either.

I'm not doubting first is stronger, just wondering if something is actually wrong with my car. I would think I would've noticed it before. I'm fairly sure I've washed the car in the same spot on the driveway without the ebrake on in the past and it hasn't wound up out on the street.

Maybe someone removed one of your sparkplugs?

Why don't you use the e-brake?

J.B.H.

Do you still have the sound tray in place?

could this be a clutch issue?

The reason I ask is because my WRX is at 150,000 miles (still on the stock clutch!) and the clutch is getting bad. I noticed once that it didn't want to hold on my driveway without the e-brake.

arent you turning the engine backwards doing this?

I would think a clutch would be slipping badly during normal driving before it would slip at a dead stop on a sloped drive. I seriously doubt it's a clutch problem. The only thing keeping the car from moving is the friction of of all moving engine/drivetrain parts and the compression of the engine. The fact that it's moving, stopping, moving stopping is indicative of the engine hitting the compression stroke of each cylinder and then the compression is dropping until the weight of the car overcomes the resistance of the compression and friction. It's a bit of a leakdown test in a way.

I'm not sure if what you are seeing is anything but the engine getting a little looser as it ages (not neccessarily a bad thing), but I would always use the parking brake on a manual car, period. I also always use reverse. As others have said, the lower the gear, the harder it is to turn the engine.

I use 1st in the garage but reverse on any incline. It's what my Dad always did. ?

Vic,

I parked my 997 on my moderately-inclined driveway in second (or third, I can't remember) without the handbrake and it slowly rolled down the slope. There's a post somewhere on the board about the occurrence and someone chimed in about second being to high a gear to hold the car.
