Sea Foam
Folks, any one has done Sea foam treatment? I have e320 2003, I can not find the break booster . I used to have Lexus and was able to seafoam the engine through break booster ( suction tube) . For E 320 how to seafoam directly to engine. I don't want to use in tank or oil.

The vehicle does not have a vacuum assist brake booster. If you're determined to do this treatment you could look around the intake manifold for a vacuum line and use it. Good luck.

Why not try the product approved by MB for fuel system maintenance. Chevron Techron Concentrate -- it is in the list of approved products. Just put in the tank and fill and drive. Worked great in my 03 C320.

I recommend Lucas fuel treatment. Cleans and lubricates fuel parts and gets water out of the lines. I've never seen seafom benefit anything other than a 30+ year old car that's sat for a while.

If we're able to use a Chevron fuel additive in the tank as another poster noted, and assuming SeaFoam is safe for MB vehicles, why couldn't it just be added in the tank?

Check this link and you will know why I want to seafoam directly to engine. There is a definite proof and cleans engine from inside

I use to perform regular SeaFoam treatments on a 02 Acura TL-S using two cans. One through the intake manifold (using a suction tube) while splitting the other can in the tank and oil. It was smokey, but ran great afterwards.

I did seafoam . As there is no break boaster , so I decided to add directly through air intake . It looks like a waffle shaped ( you need to take the whole air filter case off). While engine running ( ideal) I poured till it started to die then hold the bottle, gave few minutes to recover the engine and again poured I repeated the process till I used half can . I turned of the engine and let it sit for 10 min. Then I started the engine and drove the car on 2nd and 1st gear at 5 - 6 rpm . I drove back home and the engine check light was on. That was expected. I disconnected the terminal and reconnected . And drove again to check if engine check light comes. No engine check light . Now 2 days passed engine running very smooth and sound like a new Lexus engine ( I have to bring my ear close to engine to hear it is running) . Pick of the engine improved and most important gas millage jumped from 24 miles per gallon to 25 miles per gallon. It really makes a big difference. THIS IS REALLY A MAGIC. Do at your own risk.

If you must do this, then remove the MAF 1st....
the "waffle shaped" thing under the air cleaner is the Mass Air Flow sensor assembly. The internal MAF mechanism is a sensitive part. Do not pour chemicals, including seafoam, through it.
Remove it first.
It's easy and here's how: https://mbworld.org/forums/e-class-w...2004-e320.html
I am not encouraging or discouraging the use of SeaFoam. I have no experience of it. I have no idea if the throttlebody likes seafoam or not.
Remove it first.

I did oil change today and also did Flush . Still no check engine light . I also do transmission oil change after 20K . Actually drain and refill with 4 Q. It is pink . At 122K engine is still solid. It is because I have been following my own recommendations. Do engine oil at 3K, My last car crossed 240K and still engine was solid with good compression and no change in oil level. MB dealears recommendations does not make sense. Engine is engine still follow same laws of physics and mechanics only difference is now we have aluminum blocks and ring piston. If you can afford to change oil early then engine life will be more . Same is the case with transmission, I refill it after 25 K ( not flush) .

you guys need to be careful with this stuff.i saw a guy hydrolock an older 420SEL adding it straight into carb.he was poring very slowly also.he had a guy in the car giving it a little gas and then bam,the motor seized.a complete rebuild was needed to fix the engine.
he wasn't pouring it in any faster than a brake booster line would suck it up either.it may work great,but i wouldn't use it,unless the vacuum line was very small,maybe 1/4".
just my $.02

Your second mistake is thinking you need to change THAT MUCH oil in only 3k miles. You're wasting money, period, the end. Don't talk to me about physics and science of engines, there's no good reason to change full synthetic oil at 3k regardless of oil capacity (ours is HUGE) nor driving habits.
Your last and final mistake is automatically equating that changing oil early will improve engine life. Simply not true. You're pulling the lubricant out of the engine before it has a chance to settle into all the grooves and valleys and microabrasions in the engine and do it's job.
But please, by all means keep doing what you're doing. Because not one single Mercedes vehicle has ever made it past 100k miles without following your excessive maintenance recommendations (/sarcasm)
