Review on 💪 Efficiently Remove Studs with Shop Iron 16023 3/8" Drive Stud Extractor by David Butterfield

I have a loosened bolt on my intake manifold. I went from mechanic to mechanic asking them what I need to do to find out. Because of the location, people told me it had to be drilled, I had to weld a nut to it, etc. Everyone pretty much said I was SOL and there wasn't a single tool to get the bolt out. When I asked them what they thought of this instrument, they laughed. I saw some videos online and decided to give it a try. Before that I treated the screw with PB penetrating lubricant mixed with acetone. I assumed the thickness of the oil coupled with the age of the corrosion would not penetrate the finish so I had to mislead him. After mixing 50/50 acetone and penetrating oil I sealed the recess around the screw and let it sit for 2 days to make sure no oil was leaking out of the bushing. I wanted to prepare the screw as best I could while waiting for the tool to fit. When I first tried to use the tool it started spinning, but I soon realized it was spinning on a thread. The second time I tightened the tool enough to allow it to tighten even more. I figured I had nothing to lose at this point, having my car towed would cost me $160 and removing the bolt would cost me another $100 and up. I carefully tried to turn the bolt with the tool, but it wouldn't budge. I applied a little more force to it and felt something move. I couldn't tell if it was a screw or if the tool slipped off again. Frustrated as it is, I slowly turned back. I saw a small gap between the tool and my intake manifold so I assumed the tool worked. I got a little more aggressive with the twist of the bolt and sure enough it came out. I was like a kid in a candy store! Amazing tool, scared me of a small but amazing tool! I have attached some photos of my progress. There was a screw stuck in the intake manifold on my 1978 Corvette that I have owned for 10 years. As far as I know he never had a radiator flush so it was necessary. This should give you an idea of the corrosion I was looking at. Steel, aluminum and water! What a disgusting combination!
