I just recently had a transmission put in my benz with 207k miles. The battery went down and they jumped the car, knocking out the voltage relay. When I picked the car up,it was idling like a race horse. After several trial and errors, I found out it was probably the relay (ABS light was on) and replaced it. Afterward, I starting hearing a slight "ticking" like a lifter or valve sticking. It has gotten louder but does not sound like it is coming from under either valve cover. What could be the possible issues??

MasterCould it be the transmission flex plate or anything related to the transmission work. I hate to blame people but the first place usually to start in cases like this i the last thing touched. That engine uses hydraulic lifters perhaps a lifter is sticking or dirty, had to speculate without being able to hear the noise first had.

Visitor, May 31, 2011, 08:23Patrick...thanks for your insight. One of my mechanics suggested putting some Vlave Kleen in the oil to see if that would quiet the noise; it didn't. Should i try that a second time or just go ahead and get it over to someone to take a look at it??
