Last week my ML's 320 engine broke.. When I started it in the afternoon, it sounded like it was not firing on all cylinders and my engine light was blinking. The engine ran very rough for a minute and then it stopped. Towed it to a mechanic and found out that the exhaust valve broke off on it and it damaged the piston and the cylinder.. Got a used engine and put it in, started it up and took it for a test drive. Drove 1/2 mile and something let go in that engine. It has a big knocking sound in it.. Checked the codes and it showed that it was not firing on cylinder 1 & 4... Does anyone know what could cause both of the engines to have almost the same problem, or could this be just a coincident. I still don't know what exactly happened to the new engine but it sounds like a valve or a connecting rod is loose or broken.. Actually my mechanic started the truck this morning and the knocking sound went away for 30 seconds and it came back on... Any ides? Would a electronic problem in the truck cause some internal damage like this?
