Head stud ?
 

Is this cause for a engine drop or just a excuse for one. What brand of studs would you guy's recommend? Also what else would be relitively cheap to do WYIT,rings?

Thanks
Tim

Sorry to hear about your misfortune Tim. Do a search for user 'Doug E' and headstud, lots of good info.

In short, engine comes out and depending where the stud broke (how much is accessable) the P&C's come off. Porsche steel studs are the most common replacement, unless you want to spend $$$$ for Raceware or ARP.

I think you can do damage overtime running with a broken stud.

If your 82 cylinders are Alusil do some research before thinking about re-ringing.

The cylinders on my motor were alusil and they were bad when it was taken apart so I replaced them with Nikasils.

Tim - sounds similar to my experience in the Summer of '03 except I found 3 broken studs :shock: I have no idea how long they broken and I decided to finish out the DE season and did 4 more track days.

Middle of that November I (with a lot of help from the Dorki crew) dropped the engine and dove in. I replaced all studs with new steel ones (could really have left the top ones alone but I could only find them in a set of 24) and so far no problems. Lots of other things were done while I was in there and on Feb 1 the engine was running again

Like Chris said, do a search under my name here and on the Pelican Engine Rebuild forum and you find the documentation of my project. You can also check the Gallery on this board for pictures ... just look under the Doug E engine drop section.

The most important thing you need to ask yourself is what are your intentions? For me I knew that a track car would be in my future so I decided to keep everything stock and therefore greatly simplified my process. If you are looking for more power then get your wallet ready because the options are endless :wink:

Feel free to PM with any specific questions you might have. The satisfaction I got from doing the job myself was priceless and each time I turn the key I flashback to all those nights in the garage :)

I am in the process of a top end (if I ever get my tush in gear). Everyone I spoke to said the obvios - I'll run but the longer, the more expensive the repair. Also note that when one breaks, the others are sure to follow. There are many here who can lend helpful and sage advice.

Chuck,
How will I know what I have?

Doug,
I thought I had read about that last year. Was there any damage to the cylinders from the studs being broken? I am going stock this time around as I said I had no plans ( funds)for a rebuild this year. ; ( This will be my first attempt at a 911 engine drop so I may need some help tips from you guys.

Stick a magnet to the sides, if it doesn't stick it's alusil. I partly agree with doug on the re-ringing issue but, please note that many have done just fine w/o replacing the cylinders. Also there are companies out there that will coat your cylinders with nickle (ie nicasil). Do the reading! When you have your heads done, they will be able to tell you about the damage that likely occured to the tops of your jugs. Mine has 130k and the cylinders are not out of round.

Tim - no damage that my untrained eye could see.

Mark - what part did you agree with b/c I didn't make any comment about re-ringing ??????

Hmmm, another quote for the arms race thread? :shock:
