Sounds like you might have turned over the engine with the hill & being in gear.

You do coast in gear on a hill, the engine can turn over on a hill.

Use the e-brake, that's what it's for.

I use 1st of reverse to hold the car with the e-brake.

Maybe this is just a myth, but I've heard that if a car won't stay put on a slope (in the manner you describe), then it likely needs a valve job. I think that Grant's post above alludes to the same issue.

Surely its a myth, how on earth is a valve going to hold a car over a tonne .

I typically use the e-brake on an incline, of course, but not when I'm sitting in the car; I put it on reflexively when I take the keys out.

I doubt it's the valves, the car had the top-end done at 60k miles and doesn't use a drop of oil.

Perhaps a testament to the lack of internal friction of the rotating parts and that it's only the compression of one cylinder at a time trying to push back.

On a related note, 1st vs Reverse on an incline?

I've been told different preferences by different friends and by RL members too.

On an incline, in 1st, wouldn't the force be pushing against the gear direction and be able to hold the car better as opposed to Reverse where the gearing would be going in the same direction and create less resistance or is it not a function of gearing?

I don't know...

I don't think the direction of the gearing is an issue. As others have observed it is the combined friction and compression of the engine that holds the car. I too doubt it's a valve issue but there can ba a variety of variables that come into play here including engine temp, ambient temp, viscosity of engine and/or gerabox oil, etc. Have you had a recent service or made any other seemingly minor changes?

FWIW I've always used reverse as the "parking" gear because on most cars it's the lowest ratio. I also ALWAYS use the parking brake, especially after seeing a college friend total his TR2 when it popped out of gear on a hill and rolled into a tree.

If you are going to leave your car parked for an extended period of time (like for the winter) is it best to keep it in gear, or in neutral?

I would leave it in a forward gear if its rolling would be forward and in reverse if it were to likely to roll backwards. For longer periods of time,like over the winter, I would NOT engage the e brake, I would however chock a wheel....Be well, Jerry
