How to pull the engine?
Ladies...Gentlemen.
My -79 928 has been sitting idle for x amount of years. I am in the process of rebuilding/restoring.
The interior is "new", 19" carrera S all black is ready, Eibach/Bilstein, S4 brakes are all in the garage. Auto is rebuilt.
Torque tube to be rebuilt...soon.
I am changing the color of the car and therefore am looking to pull the engine to get it right the first time.
My question.....How easy is it to pull the engine? Anything else I should do while I am there?

Engine easy, disconnecting everything else... time consuming!
Pulling the engine itself is easy!! Four bolts and two motor mounts, and the torque tube clamp...
It's getting vacuum hoses disconected, fuel lines disconected, pulling radiator/coolant hoses, a/c lines disconected, powersteering, and wiring disconected that's time consuming!!
Draining the antifreeze out of the engine block is much easier when you know about the threaded plugs near the back of the block between cylinders 7/8 and 3/4... Makes for less mess in the garage!
Make sure you photograph and label things! Makes life much easier, and bag/label all your parts.

I think you need to pull the clutch, too and if the manifolds are stock , they stay in place right?
can you pull the motor with the clutch? Ive asked this before and most come back with a resounding "no". of not, thats not that hard, but putting it back in is.

You can pull the motor with the clutch still on.....and leave the exhaust manifolds too.....just disconnect the down pipes.....
If all goes well you can get the engine out in around 4 hours.....its a tad longer going back in....
As for things to "do" while the engine is out....the quick answer is EVERYTHING..since it is SO much easier to work on with the engine on a stand....here is my quick list:
1: Oil pan gasket and inspect rod bearings (replace if needed)
2: Both main seals
3: Full TB-waterpump job
4: replace seals on oil pump & inspect for damage
5: I would pull the intake and replace all the seals-hoses (they are 30 years old!!)
6: replace fuel lines
7: Take a serious look at AC-Power steering lines...since they are EASY to replace with the engine out
Plus a bunch of other stuff I can't remember right now...but thats a good start

Excellent.
Just what I need. This is an automatic so i assume issue with the clutch is nonexistent. I will also put headers on it when it goes back in. Great advise on the gaskets and seals, fuel lines water pump,ac, oil pump, coolant and the photographing and labeling.
I will follow up on all of it.
I look forward to that writeup also.
I guess the decision is made.

Here is a link to the removal:

and a link to the installation:

If the links don't work, let me know and I'll email them to you. If you have any questions, let me know. It's been a few years since I removed the engine, but I'll try to remember.

I just pulled a 16v engine the other day. The one bit of advise that I think is missing above is this:
There is a clamp that holds the wiring harness to the chassis found under the left side of the engine. It is nearly impossible to get to with the engine in place. I reccomend saving it until you are ready to pull the engine. Once you jack the engine up a few inches you will gain alot of access to this wireing clamp. It is held on by a small bolt and the nut on the bottome will need to be counter held as well. I believe a 10mm wrench and a small ratchet w/ a 10mm socket will be the tools you'll need. Once this clamp is removed you can then feed the harness up through the back of the cam belt cover and pull the engine.
Good luck
