Well I started the car this morning, and as you know never a dull moment.
The engine, (119 110K on the clock.) is ticking and on high rpm it knocks.
I didn't drive it.
I could not locate the sound with the covers on.
I removed the valve covers those covers were hard to remove,
it was like they had cement them.

I thought that the oil tubes are leaking, but I have the metal ones, so they don't
brake off like the plastic ones.

Was better that I could not go to the meet yesterday hm.
Maybe an angel is watching over me?

I noticed that the cams have little deposits 4" from the chain.
Oil pressure was 1,5 at idle oil is fresh 20W50.
Any ideas before I start digging?

Regards.
aam.

My first thought is plugged 'cam oil feed tube' . Please read Ticking Noise in the Hydraulic Lifters in a M119 Engine - K6JRF Auto Page Maybe they need to be taken apart and cleaned or maybe your M119 needs an Angioplasty like my Right Coronary Artery. OH..... are you ready for that expense! Hope you have a current insurance policy. If so, give Jim 'karas' a call. Har Har

I find it very interesting that you and Tony both had car problems yesterday that held you back from joining us.

Yes, you could say that your Guardian Angel was watching out for the both of you. Tony with leaking front cylinders and you with an engine noise.

Well I got a doctor suggesting an angioplasty.
I will consider that, maybe I should check my self
also while at it, two birds one stone. Haha.

Thanks Lynn, I did see the post that K6JRF it is well documented.
Tomorrow if I have some time I will try to blow the crap out of the tubes and see what,
I have to wait for parts to come in, so it is going to take some time.
But what is wrong, no body has any ideas or jokes?
Come on guys, all virgins? LOl.
Hmmmmm.
Maybe is the month or weather?
Only from Lynn, amazing.

Regards.
aam.

stepping into this deep of water, i doubt there will be many 129'ers who've torn apart their own engines trying to source out and diagnose problems of this magnitude...

all i can say is good luck aam, you've got quite a big job on your hands my friend!


let me know if i can lend a hand. i'll should be able to bring that torque wrench that you need.

Albert, I am very sorry to hear of your M119 engine issues. Under these circumstances, I am actually glad that you were not able to make it out to the meet. It would suck to find out that your engine is ticking or knocking 75 miles away from home. I wish I could pinpoint the problem but it is hard for me to attempt and diagnose online.

Well, I guess blockage somewhere within the lines of the oil tubes 'may' be the culprit and with that said, I would personally try a can of motor flush with a fresh oil & filter change and see if that helps. I am praying that it is something minor that can be easily be resolved. Please keep us posted.

Good luck to you.

Thanks Ken for the kind words.
No progress yet other then that I broke one of the metal tubes trying to pull it out
one piece is stuck in the engine, to hot to work on it.
It is so hot you can fry eggs under the sun.
I am waiting for the parts to arrive from autohausaz.
Who knows how many more will brake off.
You can only buy the plastic ones. :(
Regards.
aam.

Im obviously no expert, But I seem to remember reading in another forum it might be (not sure if this is for our benzys or my roomy's Infiniti I-30) been doing both for last couple weeks. However, I BELIEVE it could be the cam holders or cam spacers something to do with the top of the cams just under the valve cover. They are supposed to be fiberglass and just warp/wearout with time. Sorry can't remember where I came across it. Just do a googlesearch for thunk when start 500sl. I'll check my notes maybe I acn find it

RCyrus,
I didn't know that they sell them made of aluminum.
Aluminum $22
Plastic oem $19.
Not bad, but we have 16 of them. :(
Mercedes wants to have access to us every five years. ;) $$$

Autohausaz plastic oem $15 hard to beat their prices.

Benzmanbandit,
I am loosening the cam holders made of aluminum to get to the oil tubes.

Thanks guys for your help, good finds. :)
No progress yet, waiting for the parts to come.

Regards.
aam.

If I owned an M119 that needed Camshaft Oil Feed Connectors this would be the way to go assuming there are no fitment problems.

Parts.com plastic $256.00 delivered vs. Aluminum $366.00

Thanks 'RCyrus' for the great information!

Here is the scoop I just received the parts.
I noticed that the plastic oil tubes have larger inlet/outlets
almost double then the metal ones.........
Hmmmm.
So there is a reason why Mercedes did change them.

Autohausaz price for them is $198 shipped............... ;)

Regards.
aam.

Well looks that this is a tick with a strong bite.
I removed all the cam tubes blow them out, they were all clean cam caps clean,
I did noticed that the last cams uppers on both sides by the chain had a little oily black grid powder like brake dust on them.
Maybe plastic from the guides brought up by the chain rotation?

So I put everything back, started the engine and, the tick is still there....

Mercedes recommended to idle the car with new oil for a few hours, did that for about 1.5 the noise is not going away.
So that is it.
Back to the board. :(

Regards.
aam.

Aam could it be the timing chain? Please don't laugh too hard but that's what came into my mind.

Sorry if I said a nonsense.

Cheers.

AAM, how many miles on you car? I have also read about timing chain tentioner problems with the M119. If I read this correctly, you have 2 noises, "TICKING" and "KNOCKING" It could be that the oil pump pick-up is plugged or broken!!!! Before you run it to much, you NEED to find out why its KNOCKING!!!!!

Guys,
119, 120K on the clock, the insides cams etc, look good and clean enough to eat.
Chain is tight timing gears etc like new.

Mick,
I have no chain slap when starting, so tension er & chain are tight.

Yes Drags, my thoughts too, I got an oil pan gasket, which is next on the list.

Oil change was two weeks before the noise.
Have to make a pressure gauge tool,
to go from the oil sender to gauge with a tee to the sender, so I can ck psi.
If the pump pressure relief valve spring is bad.
Not easy to connect, threading problems, (Hooking on the filter housing.)
But I don't think that is the problem.

My oil gauge has good pressure idling 2 to 2.2 with clean oil, depending on oil temperature,
(No Viagra is needed.) Haha.
From the past when oil was dirty it would drop to 1.2 to 1.5.
So as I have said in my other posts out goes the old oil.
I think psi is slightly higher then before. (Memory is getting less with time.) ;)


So that tells me that I will open the pan for nothing, other then cleaning it.

Replaced the chain guide plastic rails, for nothing.........

It is like I am running after a ghost. :(


Most likely dirt in left side one tappet .
I have a bad dog tick, not a knock.

My blood pressure is up, but the S#$t didn't hit the fan yet. Lol.
As you guys know I hate not having answers.

Regards.
aam.

Albert, I don't know if this helps but I found this advice on an old MB forum

If it is coming from the engine and you have the old 4 cam 32v
M119 V-8, there is a pretty good possibility one of the valve tappet oil delivery-tubes has lost it's end plug.
The oil to one lifter is lost, oil pressure drops and the lifter starts
"tappin" . removing the valve cover and inspecting all the little
brown plastic tubes between the cams is a good place to start.
if one is missing the little plug at the bottom, that is your culprit.
If one has failed, replace them all. pn# 119 180 03 66.

AGAIN, THIS ONLY APPLIES TO THE OLD M119 32V V-8.
and is a mere suggestion of a known problem.

Thanks James for the find.
I did check.
All the pipes are clear don't have plugs.
Everything is intact, I don't want to throw out good oil and filter, it was replaced
about 100 miles a go.

So I decided to drive the car for a while before I go further.
MB recommended to idle it for two three hours to remove the dirt.

They will not remove the heads for that, under warranty.
As you know you don't need much to partially close the tappet hole.

Today after driving the noise is less and on/off, and with the a/c and closed windows
I don't hear a thing. ;)
So I will try that for now.

But one thing for sure I am not taking the heads out, at list not for that.

As you know I am a type A personality, but I need time to think, have to water
the wine on this one.

Thanks again.
Albert.
