Hey guys, I am about to purchase my third M156 AMG car (07, 139k miles). The seller sent me this video of it idling, does this sound normal? To me it seems a little louder than my old c63 but doesn't really sound like clacking/ticking from the lifters.
Let me know your thoughts, it runs and drives fine and has no errors.
Let me know if you guys have any issues opening the video, I can upload it to youtube or something if any issues.
Hard to tell from these.
Have him send screenshots of any pending OBD codes and the status screen that shows how many start ups since codes were last cleared. If he can't, a local Autozone can.
To my untrained ear, that sounds like more than one noise to me. I hear the higher pitched clicking of lifters, but I also hear a lower pitched clicking noise in there too. Seems like a lot of valve train noise to me. I doubt codes would show anything
Went ahead and purchased the car since the price was so good. I will take off the valve covers and inspect the cams and lifters and replace if needed. Everything else seems good, hopefully just need to do lifters!
Checked the cams and they seem okay for the mileage, I have ordered all the necessary parts to do headbolts/lifters/injectors. Hopefully it all goes well
You should do the cam adjusters while you're in there. Maybe the PCV depending on when it was changed last.
Luckily the PCV was done last year as well as the intake manifold gaskets according to previous service records.
Yeah I was debating doing the adjuster plates but they end up costing a lot since I'm in Canada (our dollar sucks). I'll check to see if they are loose with a wrench, if so I guess I'll have to do them.
Do you know if there are cheaper alternatives to the 63everything plates and titanium screws?
