I got the same car and have the same engine sounds like the guy in the video (about in the middle).
Someone already commented "your hydraulic lifters ticking"


Now is this 100% the hydraulic lifters?
If so: How much does it approx. cost to replace all the lifters at the local mercedes benz dealership? :D

I guess this is not an easy do it yourself job?
But i live in germany and im driving this thing at 140mph quite often. (Autobahn)

What can happen if i ignore that ticking sound?

I couldn't hear in the video. But the problem with lifters is getting good ones. INA seem to have flooded the market and in my research it seems you can get lucky, or not. MB are the good ones, really good. But expensive.
Changing them is not so bad.

Give us a video of your ticking noise if you like so we can listen.

I had a horrible ticking start once on a journey. It was the rocker surface having worn through. That was very cheap to fix, with low mileage used rockers.
Worn cams can tick too.

Show us a picture of a cam lobe, either by removing the valve cover on one side or just through the oil cap hole.

I worried about lifter quality when my M104 head gasket was replaced. I went for MB at £35 each. And there are 24. That hurt but all is well 30 K Kms later.

Easy to replace may be do them all in 1 + hour . Purchase new gasket for valve cover .See video on youtube . And INA is the type that i purchased from Mercedes for my M103 engine.

My 84 500 SEL is making this ticking sound too. I was going to start a new thread, but since this was already here and recent, I figured I'd post here. It started suddenly on a hot day while driving home. My mechanic neighbor said it sounds like a lifter tick, but as I understand those should go away when oil pressure rises? Mine doesn't, in fact seems worse when the engine is hot. I am avoiding driving it too much until I can get into this and figure out what is going on. I drove about 50 miles today trying to work out a different issue, but other than that I try to keep it less than 10 or 15 miles per trip every week or two. How easy is it to replace lifters, rockers and possibly the cams? I am really nervous about taking anything out because I can imagine bad things happen when valves aren't opening and closing when they're supposed to. Any suggestions? I hate to bother ianrandom again, but I noticed he replied above, so I'm sure he's gonna say " Dang! THIS guy again??"

Thanks everyone!

Jason

This weekend i have to drive 300 miles.
What would be the worst thing that can happen? Its already ticking for a while...
Can this total the engine? Would have to rent a car then.

I think i will take it to the mercedes dealership next week as the AC is also leaking and not working anymore.
Already refilled it multiple times but does not hold the refrigerant very long.

Hey Michael,

Ticking in the valve gear can be a true problem/annoyance depending on what is found.

Your video posted here appears to be more about exhaust sound exuberance than actually documenting the condition you have a concern over.

Maybe tomorrow, take a view with the hood open & at idle, idle plus?

It would be easier for experienced ears to tell what you are getting at.

Ignored could be a financial embarasement long term.

Good luck man.

If you ignore the ticking it will get worse. If it's due to cam problems instead of lifters, it will get more expensive. Eventually, the tip of the valve stem will mushroom from the pounding. It the short term, probably nothing to worry about. A couple of hundred miles probably won't matter.

You video is an exhaust video. Come on now

Yes ticking is lifter's. Knocking is camshaft

If your lucky like me you'll find the broken time guides now rather then when your doing 140 mph

I took the trip on the weekend anyway.
Nothing happened.

But i noticed the "ticking" is not always there.
When starting the car cold, it does not tick.
When the engine was hot after about 60 miles autobahn, it ticked.

The ticking was very noticable in the drive in (directly after leaving the autobahn) with only the driver side window rolled down.

After 10 more minutes city driving i arrived at home.
At this point the ticking was way less loud/noticable for what ever reason.

At home i made a video anyway.
You can still hear the ticking but not as loud as it was in the drive thru.

VIDEO: IMG_0306 (Sorry im not on youtube)

So it does not always tick,
and not always in the same intensity.

Im not sure what i should do now.

I'm having the same problem. Was planning on just replacing the lifters and rockers, possibly the cam depending on what I find when I get into it. When you say guides, are you talking about the valve guides?

Thanks!

Jason

cams and timing chain guides. I bet this would be going to be very expensive.
Hopefully its just the lifters.
Well i will take it to the mercedes dealership and see what they will say.

Is it even useful to repair the engine if it needs new cams and timing chain guides?
I imagine this will get very expensive when done by mercedes benz.
Might better of driving it until it breaks and then swap a low mileage junkyard engine in it?
Or i am expecting this to be more expensive as it really is?
