Review on 🔧 Enhance Diesel Engine Performance with OTC Tools 7223 Glow Plug Bore Reamer by Dang Esq

Worked really great. I couldn't install new glow plugs because of soot. You just wouldn't go deep enough to grab the carvings because of the carbon. I used this reamer tool with some white lithium grease to catch and glue the charcoal. Inserted and turned the hole with the ratchet. He pulled it out and the grease was covered with soot. I did two passes and then my new glow plugs went straight in with no resistance. The only reason I'm giving it four stars instead of five is because of the price. Ridiculously high for how easy it is. I tried renting or renting one from auto parts stores but no one had such a tool.
