: Question about stud kit install?

My mechanic has run into a problem with the stud kit installation. My block has been repaired before with inserts that failed. About half of the holes in the block do not present a problem and can be drilled and tapped fine. The other half have larger diameter inserts and the hole drilled for them is already slightly larger than the studs in the kit. My mechanic is looking for a solution that will prevent me from having to buy a new block because the money isn't there. He needs to know if there is enough meat in the block to drill holes big enough to hold an insert with an outside diameter of .656. He can get an insert that will take the stud if he can drill holes this big without damaging the block. His Idea is that the stud held by an insert is less likely to fail than than a bolt screwed into one.

Reach Jake on http://www.northstarperformance.com/ you will usually get a faster answer. You can call him or email him.

yeah reach out to jake im also sure he will chime in here in the next day or 2 probably

i belive jake said ones that his studs can be used in car's that have previously been repaired with big sirts
but you say the holes are slitly larger not sure how that would happen unless someone used a time sirt that was way over sized

My mechanic has been trying to call Jake but hasn't been able to get a hold of him. His answering machine is not even picking up. I posted here in hope that Jake would see my post and have some ideas. The engine has two different sized inserts in it now. Half of them are not a problem but the other half are over sized leaving holes slightly larger than the studs. He thinks the motor may have been done twice.

If Big-serts have been used and failed, I'm not sure there is any alternative left. You might find some info at http://www.timesert.com.

It looks like the "previous guys" put some bandaid on the engine (fixing only the affected bolt holes).

what was the cause of it going bad this time
was it any of the sirts that cracked and failed ?
or was it the gasket failed for some reason
not sure if you posted this heading back up to look now

i would assume if it was the gasket itself that went bad and not the bolts that lifted out
then with the sirts in there i was told ones that you can just put them back in with no worries unless they pulled threads out again
i think the reason they have the big sirts was for if the regular sirts where to fail or crack
but its perfectly understandable if you don't want to trust those and want the studs i know i would
but sounds like and i have been searching the forums and just can't find the thread it was in
if the studs don't work however because they are to small
jake might try and make something for you since he can make his own threads and studs now and does not have to use a machin shop or tool company for his work
maybe he can do something to get you a few studs that will fit if you have to drill bigger but then again going bigger then big sirts may cause more stress on the block and end up cracking

but for the band-aid affect you mentioned up above
if it is true that you can reuse the time sirts if they are not the reason your hg's failed then that may have been the reason they decided to only do the few with the big sirts
yeah they charged who ever wanted the job for all 20 probably but figured ill do a hack job and safe on some time

I really like this car a lot so I have decided to do something a little irrational. I am going to take a little money out of my retirement fund and order one of Jake's remanufactured engines. I just don't want to keep dumping money into an engine that may fail again.

This sounds like the right thing to do.

good idea you already purchased the stud kit right ?
or did your mechanic just know that the studs would be to big from the measurements and specs ? of the threading
if you already have the stud kit
perhaps since your going to spend some big bucks on the engine from jake he will
refund you the money for the stud kit if you send it back in

Yes I already have the stud kit. I am hoping Jake will give me a refund towards the purchase of the engine. I will be trying to get a hold of him Monday to find out.

Emilio, of course I will. I'm here to help people get their Caddys back on the road. I picked up 2 Cadillacs yesterday to use for parts and I'm picking up another one in about an hour or so. I pull core engines from running vehicles so I know I'm starting with something good.

Yesterday: 1997 Deville (base) burgundy in/out, 1997 black on black STS
Today: Silver on black leather 1997 STS.

The good cars I either keep and drive or re-sell, the ones that are no longer fit to drive or need too much work, whatever parts are worth anything come out and can hopefully help someone else out.

One engine is on order for a customer in St. Louis that needs to be completed than I can have my helper prepare the next block for the rebuild.
