"Hello, I purchased your kit in 2009 and I have gone 100,000 miles on the repair and it is still going. I was just telling someone about your kit and I am glad to see the business is going well. Thank you for your invention"~Dan N

Hi to all I'm a new member here and would like to tell you all about my over heating problems. As most of you know the 4.6 northstar has it's issues with over heating and there's tons of people who say yeah I can do it. But it's hard to find some one you can trust. Well I did some research and found jake from northstar performance. I must admit I was nervous to let anyone touch my car but jake reassured me he is the man for this job. I was sold when I called the hotel and they new all about jake and told me many people have stayed there and all had good reviews. So I booked my room called jake to ask him to do the job. I took my car to him on Monday afternoon and went to the hotel room. I got a call on Wednesday my cars ready. Jake sr came and picked me up (really nice guy) took me to where jake was working on my car. After a short awhile- my car was purring again. Jake in my eyes is a super nice guy knows his stuff when it comes to caddies. I have only put on around 800 k since the job but I am impressed in the quality of his workmanship. I wouldn't hessitate to send any body to him. Super nice guy and worth every penny. ~Dave of Oshawa, Ontario

If you are like me you cringe anytime you must use an insert to fix damaged threads and especially when the application is a head bolt. I have tried both Time-Sert and Helicoil kits to repair stripped head bolt threads with less than satisfactory results. Northstar Performance's kits are an ingenious alternative to inserts. The Northstar kits are very easy to use. Bolt a jig plate to the engine block, drill the existing holes out, rethread and install the new studs. It's that easy. You must try these kits, you will not be disappointed." ~Dennis @ Scott's Auto, Fort Collins, Colorado

"Jake, You hit nail on the head, I went out started it and it no longer had white smoke coming out. The engine smelled funny at first but I think that was engine cleaner I used, as that is slowly going away. The studs worked great! Warmed the car up and it didn't go past 12 o'clock on temp guage. I'm going to flush radiator again and change the oil again to make sure antifreeze is out of everything and drive the wheels off it. been down for almost a year. Thanks for everything! Very pleased I got my caddy back! Thank Evrett for me as well!" ~Randy in Bennet Nebraska

"Jake, Just wanted to say thanks again...Got the heads on my 94 Eldorado put back on and just could not believe how easy it was with your Sure Grip stud system. Excellent product! I have a ways to go to complete the project, but could not wait to send an email of thanks and endorsement to you" ~Don

"Good day, First off I would like to thank you for an excellent engine for my Cadillac STS. I purchased it during the summer of 2011 and had it installed by Hitfair Auto in Nanaimo BC"....."I hope you can forgive me for my impatience. But I also want to thank you for a quality product."(remanufactured engine for 2001 STS) ~S. Baldwin, Nanaimo, B.C. Canada

Hi Jake, Thanks for the quick shipping of the Stud Kit. The Studs worked excellent and the repair went really well. Engine runs perfectly and we also replaced ALL the gaskets, Heater Core and other little misc items since the engine/tranny was dropped. Thanks again!" ~Tym @ Cordial Auto
