Jacking Up a 993 - fell off jackstand!
#16
Burning Brakes
You guys know a lot more about this car than I do, but everybody that I have been talking to about 'where to jack the car up' has mentioned NOT to use the engine. (Two techs in particular that work on Porsches, one that worked on racecars, both say not to do it)
Seems that most are pretty quick to throw a jack under the car and lift it right at the engine, and I can tell by looking under the car on the lift that the previous owner(s) were lifting it from the engine, because a bracket has been bent completely flat. Still, makes me nervous....

I wouldn't recommend lifting via the floor pans. My old SC was treated this way before I got and saw the damage caused once I'd changed the old carpet. It was an easy car to lift at the jack points and the jack stands fit nicely on the rear suspension '****'.
I too have jacked my 993 via the engine following the p-car site. no issues, but it is a little worrisome at first. I use a small block of wood against the engine just as a precaution.

With this amount of sag, you'll notice the exhaust tips will rise up into the bumper cover once you start jacking from the bottom of engine. Excessive sag is grounds for an RS engine mount upgrade Seriously, this is indicative of leaking engine mounts. Have a close look around where the engine mount bolts to the body, looking for any type of 'goo' that has leaked out.
With the car on the ground, do you have a lot of clearance between your exhaust tips and your bumper cover?

A lot of threads on this "annual" subject. A sampling of the 173 threads I found.

Based on my engine moving up and down a little, the concensus is I need new mounts?
Thanks,

You can remove the mounts rather easily once the bottom of the engine is supported. At that point you'll be able to see the gap between the mount stud assy. and the body of the mount.
In your case, an inch is all the engine assy can be raise while jacking from under the engine. May be worth a look.

Can't you just use front jacking point, raise it up and slide the jackstand underneath the rear jacking point? I've done the front that way and it's a piece of cake, seems like the rear shouldn't be any different?!

I'm with jimq. When you jack the front the rear doesn't come off the ground. When you jack the rear the front does come off the ground. I know it seems weird but I just went through this procedure this past weekend.

I use two jacks. I lift at the jack point, remove the wheel. Then put other jack under suspension arm and lift to put a jackstand where first jack was used.

I measured 2x12 (or 14) to be as long as possible and usually have as little fuel as possible when i know I need to hack my whole car up.
Floorpan is thin but there really isn't that much weight (especially when tank almost empty) and that big 2x12 spreads the load well.

I have H&R springs with Bilsteins HD's, don't know if that helps.
