[B]The car was at a local shop for a tech inspection and while they were loading it onto a nice Rotary lift, I was checking out some of the old P-cars in the shop.
I turn around and guess what I see... the *** of my car is in the air being jacked up by the bottom of the crank case!

I would just document the hell out of it and make sure the shop is aware of the problem they caused just in case the crack propagates and you're out $10k for a new crankcase and bottom-end rebuild.

What crack? New Crankcase & bottom end rebuild ? It's a commonly used jacking point that everybody has used.

RJFabCab called it an indentation but whatever you want to call it, there is a chunk of metal missing.
That is probably the stiffest part of the crankcase? And if it goes you're f*cked.
And its been known to cause hydraulic motor mounts to fail.

It is an indentation. If you don't turn the cup of the jack or place a puck , it happens. It does not lead to a crack.

Thanks to all for your replies... it's been a bad day at work and I haven't had time to catch up on any of this action!
Anyhow, I know people jack the rear from the case. Heck, I'd probably do it in a pinch if I really had to, but I'm not a fan of stressing the case or the motor mounts like that. Like Jason said, if the case fails, you are F*CKED.
Sure as heck, I would have used a piece of wood or a hockey puck to protect the case.![soapbox](https://rennlist.com/forums/graemlins/soapbox.gif)
The indentation is real. The jack clearly dug into the fin of the case. I do think it is cosmetic, but the fact that it even exists just plain p*sses me off.
Everything appears fine, but it's hard to see with all the cosmoline and crap up under there. At first when I reached up under there to feel the indentation, I felt some uneven edges in the case and originally though something might be bent or at risk.
Later, however, I noticed that those ridges I felt were really just edges cast into the case (see the pic 'right side view' in the original link).
Anyhow, thanks for the reassurance and I will surely document this incident.
Cheers

I don't see any cracks, but if repetitive nicks and indentations don't add up to case failure, then they sure get my blood pressure up! LOL

It was hard to get a good look last night at the 'dent'. I felt those case ridges and thought something may have been cracked or bent.

I use a very small and affordable jack that gets underneath exactly to that metal jack point. I bought it at PepBoys: Big Red 1 1/2 Ton Aluminum jack, for $70.
After trying many floor jacks (US General, Craftman, etc), this one is my choice, because it fits in the trunk, it is light and it is low.
