actually, all I need to know is how to take the upper half of the intake apart.

Got intake off car and separated and got the 4 screws out- scared to yank on it too much. How does that "inside" come out?

I posted a reply in your other thread. Basically I had to heat it up and then gently pry the pieces apart while tapping the outside of the mani (where the glue bonds would be) with a plastic mallet and you could hear the glue cracking away. After a while you should be able to gently pry it the rest of the way apart. Just take it easy and use your head.

This is the first I’ve seen of someone disassembling a MB manifold, maybe you guys can help me?
I have been chasing this for months, dating back to when I bought a MAF sensor because I got my check engine light with the code P170 (intake fuel trim something). I changed the MAF sensor, no luck!
I kept checking as recommended for a vacuum leak. I found this leak by running the car at idle and spraying MAS spray cleaner around the intake track, near the identified location, the spray effected the idle--bingo! I applied some extra torque to these bolts and the leak went away for about a month---but now it's back!
Needless to say I need to change this gasket, but I contacted my long time MB dealer and they said that the intake manifold is not “serviceable” here—in other words the intake manifold is sold as an assembly, so the gasket and torques specs are not available! They say I have to buy the entire intake manifold---big bucks!
In the photos in this thread it looks like this gasket is really an o-ring type seal right?
Help, has anyone come across this same problem on the 320 motor? How have you guys solved this? I can’t believe anyone that is mechanically inclined would buy an entire manifold to solve this leak.
Thanks for any help

I had my manifold cleaned up by Anthony @ TVT Design.Check this thread - https://mbworld.org/forums/c36-amg-c...oject-c43.html and contact him for the proper sealant.

Is any one still doing this type of work

Is that member even active anymore? I remember that thread suddenly died and no one ever replied to it...

Would be nice to know what kind of sealant he used too since im i the middle of cleaning/polishing my intake mani...

Hi, I'm new on the forum. I took apart my manifold and I'm not sure about applying gasket maker around the ports. Did you get any resolution to your problem? The yellow line indicates the original gasket that I'm reusing, the areas marked in blue is what I'm wondering about.

May be a very outdated question, but how did you go about separating these from the external part? I accidentally broke the fork that moves the butterfly valves and I cant seem to get the internal chambers out of the lower part of the manifold to get to them..

I dont want to buy a new one but im not sure how to fix it at this point if I cant separate them..

Any help would be greatly appreciated!!

Hey,

Ignore the spots you have in blue, but you need to connect the parts in yellow as well. Essentially you should have a thin beat of RTV that runs straight down the manifold as well as on the outsides (which has a larger, thinker bead)

Here goes nothing with a gravedig....original pics aren't showing up anymore...anyone got some pictures of the port work kicking around still? Sounds like I'm missing out on some beautiful intake ****!

The 1998 to 2001 cougars are European designed and have the same intake concept.
The racing folks are gutting the secondary plates.
If you want to seal this intake properly use loctite RTV for Porsche and Mercedes Head gaskets. I have the number somewhere but it is intended for applications like this.

Recently modding my M113 and it was a necessity. Google head gasket sealants for Porsche Alusil engines. It is available on Amazon.

It is not recommended to gut the M113 intake secondaries without preparing for a re tune.
My 2 cents in this 2006 informative thread.
Cheers

Here is a link to the sealant. I would apply to all mating surfaces of intake halves sparingly.
you dont want excess collecting into the butterfly.

Cheers

thanks but I was talking about the glue. Most of it is sealant but there are two pieces that are actually glued on. Most people say use plastic epoxy, I used JB weld
