2007 Ram 2500 5.9 Cummins.. I want to do a valve lash adjustment.. Went to a Dodge dealer and had it done but to me it didn't sound right.. I mean it was better sounding at idle but on the road it sounds like the valves are knocking.. Even a couple friends asked me what is wrong with my truck.. Anyway, I want it done again by an expert, not a Dodge dealership.. 92530 zip and weekends a plus but not mandatory.. I'll have to rent a car if weekday
