Samvada Posted February 12, 2021 Share Posted February 12, 2021 (edited) Hi, I have a 2001 CL 713 with a EM7–300. The engine runs good however, it has a terrible intermittent squeak that resonates throughout the engine. The noise goes away sometimes for weeks Until recently it’s gotten a lot worse. Sound like it’s coming from the cam area #1 cylinder. Pulled the pan expecting to find metal but was clean. Pulled the EUPs and rollers all looked fine including guid pins and cam lobes. HRings all check ok. From underneath a couple intake and exhaust cam lobes Show some spalling and minor scratches but nothing chewed up. Anybody have an idea what might be causing the noise? Ive got my work cut out here, also noticed when I dropped the pan that there’s a drip of coolant coming from number five cylinder sleeve. I’m already in this deep should I pull the cam too? attached a video of what I’m hearing Thanks for the help!!
