Lifting the 911, dumb question.
 

Is there any harm on lifting my 911 using the sump with wood or something protecting it? I read a post earlier that it made the body crack. Anyway I forgot to buy the jack pad while ordering parts for PP so lifting it from the sump wont be a regular thing because I am ordering it but I just wanted to know if it was hard on the car.

not if you are careful - lots of posts on the forum regarding this subject

Nope, you'll be fine. When I did mine I took a 2 X 6 and drilled a pocked for the drain plug to "locate" after that it was very solid , resting on a large section of the case.

Thanks

I use a pad of about 10 layers of cardboard, it's works awesome. And I use a 6" by 6" by 2" board below that, which rests on the jack, works perfectly.

I use a carefully routed block of soft poplar... ok a bit of a joke.

There is a thread on this from not more than 2 weeks ago. The gist is that many say to use the seam at the back of the engine (rear of the car). Others say too risky. I can say that many thousands of 911s have been lifted repeatedly in this manner and seem no worse for it.

And this is not a dumb question. This is the type of question that belongs in tech forums. Asking why old Recaro seats are suddenly worth 5 grand is a dumb question.

I know many folks who jack on the engine, though I am not expert enough to say whether this is a good idea or not. But I can say if I were you, I'd use the factory jack or a piece of square iron bar to fit in the jackhole until you can get the Pelican jackpad, then jackstands once up.

I use an old phone book between the jack and the sump.

What's a phone book? I kid, I kid...

I never knew Recaros were five grand? Why did that happen?

your iphone :D

This, used by thousand of Porsche owners the world over....

Great use of a phone book finally vs recycle.

Well you guys that have this piece of equipment need to save them. They are becoming as scarce as hen’s teeth.

On a side note, I’ve spent my entire working career in telecom. I distinctly remember when we sold off the Yellow Pages. My how times have changed.

Back to technical content... I know it’s probably safe to jack this way. I have never been able to bring myself to do it. If something could go wrong, it would happen to me. So I’ve just carried on with the old approach.

I have been using my QuickJack for about a year now. Best investment I have ever made. It’s faster and safer and I can use it with all the cars. It is so handy.

I passed on an '87 911 once as it had a chunk missing from the bottom of the engine case. I don't know how that chunk happened to go missing, but I'm not a lift by the engine case guy.

If you jack a 911 by its engine, I'd think most of the weight lifted would be about 2000 lbs/1 ton.

Each bolt at the bottom of the case exerts about 5000 lbs of clamping force on a super thick flanged area X's 2. It's probably ok.

John Walker once mentioned jacking the rear of a 911 by the flange on the exhaust crossover pipe at the transmission end of the engine. I have used this method many times on my 3.2. Its a heavy steel or cast iron union and it makes a very nice place to put a floor jack saddle. No worries about damaging the bottom of the engine case.

Here's MHO, confirmed by a tech at Porsche Motor Sports at the most recent Rennsport:

That link does not work

to be really safe, I use two jackpads and two floor jacks. Raises the whole car up for placement of jack stands. Those points are the balancing point of the car. When raised on the pads, the car is like a teeter totter & placement of the jack stands is easy.
