Should i split it?
 

Ive got a broken head stud with 90000 miles on my 82 sc should i just do the studs and top end or should i just do it all? What to do ?

I am in the same boat. I have the outside exhaust stud pulled on Cylinder 1. Honestly, I have little experience so take my comments lightly...

Try to gatyer data to support a decision, maybe do a leakdown and compression test. Take into account what cylinder has a broken stud.

Ask yourself if you are willing to pay the extra cash of full rebuild. I will assume you will be DIY. If you DIY to learn, why not learn it all. If you are DIY to save cash, why open it?

If you teardown the top half and see troubles, I think you need to redo it all... I hear the "experts" say teh bottom end is anintimidating thought, but isnt really hard to do...

I have done what I think is best, cry like a sissy to the wrenchs in my local PCA region, and coaxed them to my garage (with their tools) with beer, food, and motor work -- this stuff is the hunting equivilent of a salt lick... I figure pay the mechanic a ton of cash to do the rebuild, pay him to redo my rebuild, or buy lots of beer and food and look as pathetic as I can...


I hope this somehow helps you...

Do the full monty.... its really not a big deal

I do however have a friend with a 3.0 going on 200,000 original miles on a track car....we are taking bets when it will finally blow LOL

If I was in your shoes and planned to keep the car for a long time, I'd refresh the whole engine.

I am currently re-building my 1980 911SC.

I have split the case and have just received the last of my parts that have been either reconditioned or machined. It has been a great learning experience I tell ya.

When this project is complete I know this engine will be as refreshed as possible, almost brand new. Of course... I was bitten by the "while I'm in there bug". So beware and good luck!!

That's not a whole lot of miles. If the oil is clean, the engine doesn't leak, etc, I would put it off and drive it this summer. If however you are going to open up the heads, then do it all. I would suggest fixing the head stud, put it back together, and enjoy.

Thanks guys im torn my Buddy whos a porsche mechanic says to fix the studs and do a top end. I want to put some hotter camsin and he thinks im nuts. $ is sorta of an issue and the trans syncros need to be done also along im sure with other tidbits in there. My thought is to drive it this summer and have it as a winter project My focus now is restoring my goat. Thanks again

Sell the goat and do just the stud!! :-))

Sell the goat? not a chance although a pig on gas the torque is incredible. If im in there ill do all the lower studs. Still not sure about opening it up im leaning towards the top end rebuild.

You don't have to seperate the heads and cams to fix broken head studs. You can pull the whole thing as a unit, fix the head studs, and slap them back on. There are things to consider around keeping it TDC and marking the cams but you'll save yourself a lot of hours by not disasembling the heads.

Break the case halves and checkout your bearings! Everything seemed fine on mine, but my #8 bearings were worn at 105K. Several others have posted a similar experience. This will also give you a chance to ensure everything is up to snuff and re-sealing the halves is not that difficult.
