Hey everyone! New member here! Okay, so my first post is definitely an important one for sure lol. I just finished a huge amount of work on the fuel rail/injectors, upgraded the vacuum lines to the larger Lindsey Racing ones, and re-sealed the oil separator because I had lost a ton of low-end torque over the last few months, and by doing all of this, I think I isolated a VERY large problem in my engine that I didn't know I had.
The engine began to rattle a tad, but nothing too crazy. The next day, I took it out and the oil pressure dropped to 0, and the engine began to rattle and knock like crazy, and I lost almost all power. I immediately pulled the car over and got it towed to my mechanic, who's going to do a diagnostic look tomorrow. Still, I was wondering if you guys had any insight as to what might be causing this? It could be good to give him some 16v-specific points of interest to look at. Here's an attached video with the most intense knocking it's had. Also about a year ago, the car was running a bit soft in the 2 cylinders closest to the firewall. Here's hoping it's not too serious.
