Has anyone here ever had their renosance ( SP)flap replaced?

Now before you start saying bless you, its the seal in the EGR valve.

Someone here about 3 years back told me of their turbo going bad, today at the dealership we are looking at this valve first to be the problem for the leaking oil.

haven't heard of that one yet. I've heard of the fog light wiring harnesses to be bad, creaking seats and dashes, injectors, and glowplugs. This is a new one on me!

The whole way the question is asked is a little confusing.
To the first sentence of the question, the resonance flap (spelling IS correct) had been a very big problem on the 606 Diesel engines, haven't seen one act up for awhile now. They get sticky and cause engine surging. There are 2 of them, one is in the cross-over intake tube, the other is in the intake manifold itself. They are vacuum controlled. They typically just need the carbon cleaned off, not replacement.

The rest of your post, I don't understand what you're saying, ie the resonance flaps won't cause an oil leak and isn't related to the operation of the egr.

I also don't understand how someone posting a message here 3 years ago about getting a turbo replaced has anything to do with your problem.

You used to hear some complaints about these flaps in the '96 & '97 non-tubo models. Apparently the flaps would get a little wacky and make the car surge constantly as it cruised down the road. Apparently it was pretty damn annoying. I think Larry Bible had one of these and sold it mostly for that reason.

Can't imagine what these flaps could have to do with an oil leak.

Wow, the tone on this board has changed alot since not being here awhile.

Sorry to have put anyone off in my original posting.

The way it would have been nice to answer is

" What exactly do you mean by this.." ?

So, here is what I meant.

Under the Intake manifold, there is the EGR valve, correct?. I am thinking that this is what it is. Mine has been leaking for some time, yesterday while the dealer was doing an oil change, you could see oil accumulated(sp) on the bottom of the pan and leaking into the body pan underneath.

The factory rep from Toronto I made aware of this, and he indicated that it is the 1st he has heard of this problem.

The mechanic yesterday said it is the flap that needs to be replaced, and I take it that this flap is located inside of the EGR valve itself, is that correct or not?.

In instance to the Turbo, a fellow 606 owner stated quite awhile ago he had his replaced as oil was leaking from his bearing, which I was thinking was possibly through this EGR valve itself. But, I could be wrong on this.

The amount of oil leaking from this has gotten worse, in the 3 oil changes that I have had with the bottom pan off, this is the 1st with time I have had active oil leakage visible on the bottom of the pan.

I have had the oil pump replaced with the 99 unit last year.

Anyone whom has knowledge of this I would appreciate to hear from

Chris,

While these cars more than likely have an EGR valve, it is not a likely source of the oil leakage you described. The EGR valve is used to control the amount of exhaust gas recirculated from the the exhaust manifold to the intake to limit combustion temperatures. This limits oxides of Nitrogen during combustion, which is one of the exhaust gas emissions controlled by the EPA in the US and a similar agency in all likelihood in Canada. Unless there is a lot of wet oil in the exhaust of your car being fed back to the intake through the EGR (exhaust gas recirculation) valve, I am not aware of how this could be the source of your problem.

Oil getting into the intake manifold and leaking out a joint or operator penetration at the flapper valve you are talking about is more likely either coming from engine blow-by, which is also usually fed back to the intake manifold to be burned by the engine, or from the turbo seals that keeps bearing lubrication oil separate from the exhaust and intake manifolds. I do not think there are any other common sources of oil getting into the intake manifold, other than valve seals. Valve seals on a Diesel, especially a turbocharged Diesel, should really only leak when the car is shut off as the intake manifold pressure is going to be at or above ambient air pressure, so there is not the same pressure balance to drive oil past the valve seals with the engine running.

How is your oil consumption, and how many miles on the car?

So, while I am not entirely sure of all the facts I just spouted, I am very interested in the scope of the problem you have described, so please try to get the dealer to be a little more precise in explaining what the issue is. Especially if it is not the turbo seals, blow-by or valve seals.

Good luck, Jim

The EGR valve is over on the other side, near the turbo. The valve on the bottom of the intake is the second resonance flap I so rudely mentioned before, I have never heard of or seen it leak oil, but perhaps if the intake manifold were filled with blow-by oil....????
Hopefully this isn't the case, how many miles on the engine?
I've never heard of a replaceable part in an egr valve. Perhaps he means he wants to replace the resonance flap? Again, I've never heard of "leaking" being used in reference to this flap, just sticking.
Sorry if my writing style turns you off, you're not the first, I do like to help though. What I lack in tact I make up for with, hmmmm, well nothing really, I'm just tactless, see my "location" on the left side of this post.

gbt,

I like your style of writing ... most of us are dealing with technical issues and appreciate technical fact and information more than anything else.

I am always willing to listen to someone who knows what they are talking about ... it's the other ones I have the most trouble with ... y'know, the ones that don't know anything and are spouting facts.

Roll On.

The car has 105k on it, which is about 65K in miles, and uses no appreciatable amount of oil. Probably after 10K it might use a half a litre, so blow by is probably out of the question.

The flap in question is directly under the intake manifold, and if memory serves me correctly, there is a tube that connects to this that is routed behind the engine and then down to the turbo itself.

If this is not the EGR Valve, where exactly is the EGR valve by the turbo?

I will go check again, but as one poster said, it might be the bearings on the turbo, someone else here a few years back had that problem also.

My turbo is the KKK model, but if again my memory serves me, there are 3 different manufacturers of turbo for this engine.
I had a 606 e-mail group going a couple of years back on an old computer, but the stork brought me a gift so I have been very silent on this board for awhile!

This model is probably the shortest model year in Benz history( actually in North America), it has been an interesting last few years in trying to find people that have these models, they are a fantastic car indeed, its just finding others whom have been through what I have!

Anyone else with ideas, or comments to this post please let me know!
