I have a 2001 Deville and I stopped it from overheating by drilling out only one stripped out bolt hole. I didn't buy the $400 NP kit. I bought a $150 kit off ebay. GM stripped out one head bolt hole when they built the engine. When I installed the heads. I only torque them to 50 lbs-ft. Don't worry about the angle bs. This is the reason the threads were stripped out in the first place.
I bought a Cadillac STS with North Star. Thought it had a blown head gasket, replaced it was putting new one and discovered it was actually stripped head bolts causing the problem. Left everything new in place and drilled the bolt holes out to half inch and tapped them. Vacuumed out the metal bits. Slapped in some new bolts and had one of the fastest cars I ever drove.
Hi there, the bolts included in the NSP SureGrip Kit are different from the original bolts. The NSP bolts are larger - bigger around and have different threads -- which is why the block must be drilled out, like what Jake is doing there. @northstarperfornance
Hi. No you shouldn't have to restud your block. After it's studded you shouldn't have any head gasket problems ever again. I guess if for example, you had a defective gasket that needed replacing you'd just replace it -- removing/replacing the head studs themselves shouldn't be an issue. I'm not a mechanic though just a Northstar owner. I will try to forward your question to NorstarPerformance: th-cam.com/channels/2gRqUAOgVL45SjNzYbZIkg.html and see what they say.
How much did just the head stud kit cost you? I looked at their website and only seen a price for both upper and lower block stud kit and head gasket set combined. When I saw it I went, OH MY! I've tried contacting them for price and availability for just the head stud kit, including drill/tapping jig, but they never got back to me with an answer.
If only ya didn’t charge an arm a leg an eye with a side of Kidneys and a lung just to get this work done or I’d be send myself and family to these guys cause we a really big family and we all love caddy’s
Expertise and skills are not free. Not a small job when the engine is still in the car to start with either. Great tool design. Excellent repair method. Its only 650.00. That's not too bad considering what this tool and kit will accomplish. Its a block save.
@@twiztid6977420 yes I do know how much work it is and as long as I have the time and the tools it wouldn't bother me a single bit ever since I've wrote this comment about a year ago I devoted time an patience so I know how to do the work myself and it's not all that bad as long as you have the tools the time and the parts and the space
@@twiztid6977420 also depending on if you pull the motor yourself and send it into a place a couple people said they'd do it for a 2000 but if I sent the whole car and it'll be 6000
And people wonder why GM lost the faith of its customers. I was sitting at a stoplight today and what looked like a 3 year old Terrain pulled up beside me with paint peeling away from the front and rear wheelwells!!
@@SD-pi9co 🙄Buncha Marys… The 4.0 was even a little better, have an Aurora downstairs with almost 200K in it and no problems other than leaks some oil… as long as you maintain them regularly they’re usually fine.

congratulations, also recently rebuilt the entire engine, new pistons, sure grip from Jake, all new, best regards from Poland
Hey bro where are you located?? I have a 98 STS I'd like you to look at
@@grindhard4312 I’m from New Mexico, however I don’t do for hire mechanic work. You could probably fix it with a little coffee and determination.
@@eprofessio No problemo bro just thought I'd ask ✌🏾✌🏾
So ..did u use NorthStar Performance Bolt jit ??
Also did you still/tap both blocks with motor still in the car ???
Tnx
No courtesy spit before cutting the new threads?
Incredible job
Can you do this with the short block assembled? Pistons, Rod, and Crank in place? All surfaces taped off completely.
Where’s your shop
Hi crickory the you have to use the same bolts or different than the originals please let me know thank you very much

Have you have any head gasket problems after this?
Hi. Sorry for the delay. To answer your question, No, not at all. Temperature and engine running is all good at around 4,500 miles since studding.
Can you do this with the engine still in?
01 October 2019 Update: 15,000 miles since studding and engine and coolant temperature all fine.
@@crickory still driving this car?
@@trentyjones228 Wouldn't recommend it, it can probably be done with enough finesse though
To you have to re stud when u change head gaskets?

Have you added anything else to the car , like there tuned pcm ?
No. Only because the PCM Tune isn't available for my model year (2002) yet. I plan to when it's available.
Are you guys still doing these repairs now? or only selling the kits?
They have certified repair shops on the site I think

OMG PAINT? NO WAY OMG OMG ENGINE FAILURE DUE TO PAINT.
shhh snowflake men are talking
The vehicle may a have been repaired after an accident.
U don't need that stupid ads x
Don't buy this product you will never get it he will take your money
Did you ever get your product, or a solution?
Typical GM crap. Take a a real mechanic to fix problems designed by college graduates. Never buy any GM car.
Calm down, Karen. All manufacturers have issues from time to time and this engine is awesome once this issue is fixed.
