I recently fully rebuilt my magnum 5.9l engine. Recently when the engine is between 1200-2000 rpms it makes a bit of tick/chatter noise. If I rev it any higher it sounds smooth. If I quick rev it it sounds fine. Only makes nosie when held at below 2000 rpm. The motor has a comp cam, new lifters and new heads installed. New Hughes valve springs. Engine only has 230 miles on it. Oil pressure seems great. Never drops below 35 at a hot idle. Here is a video. Tough to hear. Any help is appreciated. One thing I will say is my dumb self kinda cheaped out and bought cheaper lifters. Only thing I cheaped on like an idiot. I have more videos if yall can't hear it good enough in this one. Engine seems to run great.
