Just installed the Stud Kit from Northstar Performance in my '99 Deville. I looked at all of the different options and just figured that since the pricing wasn't all that different between the various kits when you add in the cost of a new set of head bolts I'd go with the studs. Racing engines all get studded and I figured those guys must know what they're doing. When I had questions I was able to call and speak to Jake who didn't seem to be in a hurry and took plenty of time with me. I have driven a thousand miles since the repair with some WOT and long distances on the freeway and my temps have been rock steady. The motor purrs now. I'm very satisfied and confident that I won't have to revisit this issue again with this car. Now that I've done one I wont be afraid to do it again. If anyone has any questions about the process feel free to ask.
Nice posts. I can appreciate all the effort you put into the detail descriptions. I haven't gone through this section yet, but I will. You left some very good information.
Here are Jake's studs that I received for my eldo.
I took pictures of two studs, the plate and it's mounting hardware.
If you notice the mounting hardware has two sets of different size bolts. It's obvious the smaller of the two are the original size bolts.
Look at the larger bolts and the thread pitch. Look at the studs. The larger end of the stud is what is getting bolted into the block, now compare that to the fine thread on the mounting bolt(smaller threaded mounting bolt).
It's night and day.
The stud concept seems to make more sense than using bolts.
Far greater strength, plus the torqueing action of clamping down force takes place without twisting on aluminum threads.
Why take the chance of ruining the threads when you can tighten down the nut/washer combination?
In the end I guess it boils down to your preference. In my case, it's studs.
I'm now deciding whether to use that cometic multi layered steel gasket after reading AJxtcnman's post.
I was comtemplating it already but now he's almost shoved me in the corner with his pictures of the factory headgasket "crunching up" in certain spots.
I plan to keep this car a while and I'm NOT going back in to do this repair again anytime soon.
I like to fix it and forget it.
So my 01DTS has blown its gaskets, 99K never over heated, I want to do the studs and the composite gasket but because of my work and where i live theres no way id be able to do it on my own..Can ANYONE reccomend a shop between Austin or San Antoino that can do this work??? I LOVE MY DTS and makes me ill at the thought of getting rid of it
I'm not the best with Texas geography but there's a shop in Dallas who will do the work for you. North Texas Performance. Also Crest Cadillac in Plano, TX.
Yeah I found a listing for the shop in Dallas. I appericate all the help guys! I really do!Quote:
Jake, he posted this somewhere else, too. I think there were a couple of replies concerning Texas shops
I have a 95 sts, timeserts where done about 90,000 mile ago and it’s now leaking again, with your history in this problem would it be possible to do additional repairs at this point? I used to be a machinist so do as much as possible myself if possible and if having the specialty tools
did you pull your engine out the top or bottom?
