When I first fired up my 390 a couple of months ago, it ran smoothly. But recently it started running rough. There was a load tapping noise under the left valve cover. When I removed the cover I discovered that there were bent push rods in the 3rd, 4th, 5th, and 6th positions. Likewise the right side had bent rods in the 3rd and 4th positions (see photo).
How was this engine even running?
Can anyone offer advice as to what caused this and how to remedy?
Thanks very much.
