### ⭐⭐⭐⭐⭐ Review
*by A***O on 24 November 2023*

Haven’t had any leaks. I took an x-ray because i wanted to drill and tap two holes to mount a couple of MOSFETs and I didn’t wanna accidentally drill into one of the coolant channels. It turned out the coolant channels inside the block were too narrow for screw size I wanted to use. I used super sticky thermocouple tape instead. I could probably still drill, and when I hit the cooling channel I could immediately stop drilling, tap the hole, and use a very short screw so that the screw doesn’t block the cooling channel, then add some locktite or rtv to the threads, but I did the lazy thing and used the thermal tape, lol
