Hi guys,

This is only my second post here, however I'm monitoring this forum for quiet some years now. Especially for the technical information.

I have a '90 964C2 with 207k km's.
I'm planning a complete revision with off course replacement of the clutch.
Furthermore some little stuff like brakes, new lenses, new alarm etc.

At this moment I'm very much in doubt to remove and refit the engine myself.'
I have some technical experience but I never removed an engine (of a car).
My father is going to help me, he used to be a mechanic (ships).
I have enough space, and also the right tools.

As I look trough the several topics, it seems to be not that hard.
Am I right about that?
Is it 'doable'?

Need some advice here.... Please?

 

You missed a critical factor ... time? How much time do you have?

You can pretty much learn anything on the www .. so if you have time and patience, then I can't see how you could go too wrong.

 

Time:
A week to drop,
two weeks to refit.

 

Can you list what tools and books do you have? That would help us identify if you are missing anything. Adrian's book was very helpful for me.

 

Books:
- Adrian's
- workshop manual

Tools:
Jack (normal)
Motorbike jack: want to make a wooden frame for engine on top of this
Jackstands
Just any handtool you think of.

 

Sounds like you have the right tools, motorcycle stand is incredibly helpful in lowering the engine out of the car.
The engine drop is not that hard, not time consuming - plan for about a day to two days even with little experience.

One note - I left the transmission in the car when I dropped the motor - DO NOT DO THIS - you can, but it complicated maters by about 10 fold when putting the engine back in.

Overall that job is very doable - and you will get to learn more about your car than you could ever imagine!

A lot of guys on here have dropped their motors - ask away, there is a ton of knowledge here.

Good luck

 

Blok,

I did my first engine drop about a year ago and it was a very enjoyable and rewarding undertaking! I went heavy on the pictures to make sure there were no questions upon reassembly. This post has a link to the pics...hopefully they will help you get an idea of what is involved:

Yeah, saw your topic with all this pictures.
I copied them all very helpfull!

 

Yeah, you need more than just a floor jack to get these bigger heavier motors out and back in. Book on an R&I is 10-11 hrs so you will probably need 20 + whatever eles you are doing.

Air would be helpfull taking it out but I usually don't use anything but a low touque air ratchet to put it back together and then doing a final tightening with a proper torque wrench ~ and there is a torque spec for EVERYTHING on a Porsche.

So make sure you have a torque wrench in all three flavors.

Sometimes the trickiest thing is getting the rear high enough to get the motor out especailly with a motorcycle jack. Get as high as you possible can before you have motor on the ground and figure out you need the car a couple more inches higher.

But otherwise it's not terribly hard and a whole lot cleaner and easier of job than a water cooled car.

 

I haven't done an engine drop but most jobs seem to take about 5 times more than the book value that a professional should take.

 

I guess it all depends. I can't imagine it taking even 10 hrs to pull an aircooled 911 motor even on a turbo car. 50-55hrs? Unless maybe you'r drinking lots of beer!

 

Well, as you are all quiet positive.
I decided to give it a shot.
Thanks for the reactions

Busy with preps now, Will start upcoming friday. As reading trough the
different topics I was wondering if you were able to drain all oil when it's cold.

And how to drain the rest after removal of the engine?

 

Please take lots of pictures and inform us other newbies on what goes easy and what goes wrong. :-)

 

yeah.. it was on my list for this winter, but then it makes shooting models and other things quite impossible to do in my garage if the car wont move.
