Hello,
I have a 1996 gm c1500 5.7 Vortec (miles are unknown as I bought it off Facebook). After installing the motor, I noticed a slight knock in the motor. I'm nervous that it may be a rod knock. The noise doesn't become louder when accelerating. I only hear it at idle. Oil pressure seems to be fine. 70 PSI and cold start-up. 40 PSI warming up and 20 PSI once hot. Going down the road, I have 40PSI. A link to the video is posted below. Any help will be greatly appreciated. Running M1 5W/30 full synthetic.
