911 SC 3.0 with 3 head studs broken

[Mawa]

Hi guys I need some help.
The other day I was changing the low valve cover gaskets and I saw 3 head studs broken it has a little damage in the crankcase.
Everybody told me to repair it. I am scared because the "I am in there... syndrome".

I am not an expert repairing the Porsche. I am thinking about do it my self, but my girlfriend wants the rebuild time for here
I am not sure when I open it, if I will see all the issues of the 911.

I just bought the car, and I have not a lot money so... to do it in the mechanic garage it will cost a lot money.

I have two questions, how much time will I waist rebuilding?
Is it worthy if I do a rebuild if the crankcase is damage? I mean, to buy a new crankcase or a second hand engine?

I didn't "waste" any time and it was about a 6 month process to drop the engine, cleanup, remove and replace all the lower studs, assemble and install. It seemed like all my available free time was spent on the project but there must have been some wife time in there! Although I had never worked on a Porsche flat 6 before I found it to be straight forward with all the books and available help from this forum. I did have previous auto/aircraft mechanical experience and most of the needed tools. You could spend a lot of money purchasing tools, specialized tools, jacks, engine stand, hoist, etc.

Case issues? I think it would be hard to evaluate until you have it apart. I was lucky in that my broken stud had enough remaining outside the case that I was able to get the piece out without much trouble. If any of your studs are broken off at the case it will mean taking to a machine shop for repair.

Good luck with your repairs.

Want to do it the cheapest way possible? Buy a working replacement engine.

Yeah, it's 30 years old and yes it's not going to be as reliable as a freshly rebuilt engine, but it's going to be a fraction of the cost of rebuilding it yourself. Figure $10k for a rebuild.

Thanks guys,
I am trying to find a rebuilt engine in Europe, exchange it. this process I see it more expensive but faster.
Cheers
