lifting the car

1987 carrera,
I am going to perform a full tune up including valve adjustment. After removing the oil and filter the night before, The rear of the car will be lifted and jack stands placed under the torsion bars on both sides. my question is: What is the best way to secure the car from rolling off the stands? (wheels were taken off).
Also...I saw some pictures of people placing the wheels underneath the car...just in case...where should the wheels be placed if this is advisable?

If the front of the car isn't up in the air, simply chock both front wheels fore and aft.

If the worst should happen, and the car’s jack stands fail, the wheels under the car will prevent the floor of the car hitting you if you are under the car at the time. Or at least, only squish you a little, not flat.

It is just a belts and suspenders approach.

If the car is not level (or close to it) will you still be able to drain the max amount of oil out?

lifting the car

I was going to drain the oil prior to lifting it...flat surface. then lift the car from the back with my hydrolic jack and post the 2 stand jacks, liftimg the car approx 6 inches. this will provide me additional height to more comfortably do a valve adjustment. (front wheels are on the ground)

my question is: what is the best way to secure the car from rolling off its stands?

Chock the front wheels and place the rear tires under the car just in case. Drain the oil with the car on the ground first.

I do not believe that lifting the front makes it safer and secure from rolling over...

With for wheels off the ground, it will not roll.
You can push it off the stands, but it will not roll off.

I'm not much of a safety nanny, so that might be to blame...you aren't going to easily get the car to roll off the jack stands if you are using the torsion bar caps and jack stands that have a \__/ shape pad.

. . . Picture worth a 1000 words . . . and, "What, me worry . . ."

Engine drop with jack stands on rear torsion bar caps and front tires on 4" wood blocks .
My son and I have done this several times before buying the Quick Jack . . .
Wish you the best on your projects,
Regards,

Working in the Chemical field for over 25 years, safety is our priority above anything. Fortunately I have used some of the safety methods I have become accustomed to and have applied those to working on my car and home. So become a “safety nanny” my friend and save yourself a boatload of medical bills..lol
