![Question](https://rennlist.com/forums/images/icons/icon5.gif)
I'm in the process of replacing my sHARKs oil pan gasket and motor mounts. I read I can replace the mounts by raising the motor by the oil pan but I can't see how to support it from below when replacing the oil pan gasket. Any ideas? I think I need to rent a shop crane to lift up on and support the engine to do this part of the job. Does anyone know exactly where the lifting points are on the motor? If so, is there any special lifting rig needed? It's a 1987 S4 Auto. Thanks. <img src="confused.gif" border="0">

Rich - I just replaced my motor mounts and oil pan gasket this past spring. I used an Sears engine hoist to lift the engine. There are usually 2 lifting points (on the earlier cars anyhow) on the engine (I saw at least one on PET for '87). One is found on front pass. side of the engine and the other at the rear driver side if the engine (you'll neet to remove the airbox to see it). You'll need to drop the power steering rack, lower control arms, and cross brace to drop the oil pan (I did anyhow). Here is a link for motor mount replacement plus a whole lot of other good stuff. <a href="http://members.rennlist.com/v1uhoh/index.htm" target="_blank">'87 928 S4 maintainence</a>. Good Luck!

I just finished the same job (W/rod bearings). I made a stand out of 2x4's to support the engine while I did the pan work, worked like a charm. The car was well supported and if I remember right, the 2x4's were about 19" long and set right on the block after the motor mounts were removed. Once I finished the pan work, I lifted the engine back up by the pan and finished the motor mounts and crossmember.

Rich,
I made a hook to be placed on the three bolts for the ventilator (made out of 6mm (1/4") plate
Then two pieces of wooden blocks (approximately 30 cm (1 ') long) shaped for the bonnets (in the edges over the bolts for the bonnets)I covered this with polyester tissue for protecting the lack
Then a beam across placed on top of the wooden blocks (bolted to the wooden blocks)- this beam is fitted with a lifting bolt/hook in the middle
With this arrangement you can lift and lower the car as you wish, and that's safe!

However you do it, just remember that you are lifing the complete engine, clutch, and half of the torque tube, so you are holding up over 700 pounds!
Be safe!

Thanks everybody. I found the brackets on each side of the motor to lift it by. I'll probably rent a shop crane to do the job. It now looks like I'll have to replace or rebuild the steering rack as well. I took an oil bath when I climbed under it this morning. I noticed one of the boots had oil drops accumulating on the bottom and pulled it away to see if it was the rack. <img src="graemlins/cussing.gif" border="0" alt="[grrrrrrr]" /> It was. I also need to replace the AT coolant line. What is it with this car and leaks? I'm convinced the only way I'll own a Porche is up on blocks in my garage. Here's another good example of why a pre-purchase inspection is a must! <img src="graemlins/soapbox.gif" border="0" alt="[soapbox]" /> Anyway... back to work.
