No did not make it. Got back later than I thought from KY. I just got back from meeting the MTFR group down at Casey Jones Village. Had a good turnout. Hope your day ghoes successfully with all of this. I am off to change the radiator in my Suburban. Probably not as much fun as you are having...

finally got all 12 lower studs in, ive fixed a lot of broken bolts and studs before, but nothing like this. Strange how all came out so easy but 2. Anyone thinking about replacing those 12 lower studs be prepared, this was no amature job.http://forums.pelicanparts.com/uploa...1250726193.jpg

Hey Don... gonna have it all back together for the last PCA Sonic Drive in this Thursday?!?!

You should come out anyway. I should finally be able to get out. Maybe Scott can drive?

wont be going anywhere in the pcar soon, mach. shop has had my heads for almost 2 months now, but will stop by the sonic, got some things that belong to you.

Look forward to cathing up. Been awhile.

Snap-On stud remover plus impact wrench........
 

Don,

I don't know how I missed this thread. I could have saved you from lots of aggravation. The first time I replaced the Dilavar head studs of my SC's engine in 1999, it took me a good day (8 hours). Intense and nerve wrecking experience.

However, I did an engine teardown 2 months ago and have to remove 2 broken head studs plus 10 good ones. Since I was doing a process (new to me) for removing these stubborn studs, I was skeptical about it. To my surprise, it took me just over half hour to completely remove all 12 studs without heat!!!! Actually it was about 35 minutes from first stud to the 12th lower stud. It was unbelievable!!!!! As long as there is enough stud left for the collet to grab, this is the way to go!!!!!!

Our good friend Tom Butler has shown me how it was done. So I would like to share this experience with other members who would do similar task in the future. HTH.

Tony

I used a lot of heat on the case at the base of the case. MAPP gas, let it burn for about 5 minutes, used a Snap On collet tool, and a big long bar. None snapped.

Good luck to you.

snapped extractor
 

I had the same problem.... To compound the situation the bolt extractor also snapped in the hole as well.

I sent it to an engineer - he used an electrode extract. Costs peanuts and gives you piece of mind. Also, not a bad idea to get the engineer to tap all the holes just to tidy them up!

I consulted with John Walker before I did mine, and I had no trouble. I put oxy/acetylene heat on the cylinder spigot surface adjacent to the stud I was working on. I let it get pretty darned hot. They all unscrewed smoothly. I kept the heat on the spigot until the stud was entirely out.

Tony I guess im not familier with that tool. Live and learn. It was character building anyway. Ended up using a time cert on one, it was just a little to wobbly Now if only the mach. shop will hurry up.

Missed you last night Don. Not much of a showing really, mostly Boxsters. But we did have mine, another SC with 24,xxx miles (Jay), Dave's (Blue Sky) beauty of an RS interpretation, and Chuck's 993. You and Scott up for a quick trip for breakfast in Counce tomorrow. Trying to get a group to meet up with David Bailey.

sorry i wasn't there Shane, Thur. is golf day and im usually done by 5, but because of the nice weather the course was packed and did finish till 7:30. Next time you are in town, give me a call and come on by.
