C230 M271 Intake resonator delete and egr Hose PICS
Only got one response on my first thread on egr and hose, tks, you know who you are, and I couldnt find any theads on this site. Its been over 4 years since this car has come out, someone must have done something. Anyways I did it myself
Here is my first step on the new pipes made for ic. My purpose for this was to provide a better flow of pipe, and to delete egr hose of hot gases back to ic. Also to wrap the pipe with heat resistant tape to keep air cooler.
Better response to me, and pretty sure is going to run cooler once I wrap it all up.
If anyone is interested this is what you need.
1. 2.5 od aluminum or pcv pipe, 17 1/2 long
2. 2, 2.5 silicone hose
3. 4 clamps
4. Thermo tec, intake wrap
This weekend I will post new pics of hose and pipe that goes to throttle body which is real restrictive.
Also if you look at the last pic you will notice blow by oil coming from hose leaving top of engine to intake. A oil catch can is defintely in the works!!! Cant believe oil came from top of engine , to intake hose , throught super charger into factory intake resonator..!! I also removed the pipe to throttle body and found more oil. This is definitely a design problem.. Car only has 22k , must be the 0w 40 oil being used. Might be switching to 5w 30 to help the blow by. Any suggestions? or ideas?

I used to have a celica that PVC charge piping for my 'backyard mechanica' turbo kit...
i gave up on these antics a while ago, as things like this, although worked 'great' at first, you always had to tinker with later to keep them in place
i'd recommend www.turbohoses.com to get some silicone couplers i the size you need and www.burnsstainless.com to get some pipe that will hold up to the heat ...
as far as the oil goes... it's called a PCV system (postivie crankcase evacuation system)... it's not blow by because the oil sucks or the pistons are shot, it's a by product of having a supercharged or turbo charged motor.
for emissions BS MB is forced to have this oil re-consumed by the motor) ... if you take off the top plastic engine cover and look in the back behind the MAS there is a rubber hose running from the engine head to the piping after the MAS... purchase an oil catch can and install it in series with this hose and your oil problem will disappear... that is the right way to solve it...
don't change to thicker oil as that will be reducing the lifespan of your motor....

I'm kind of confused. Did you delete the old thread? I went looking for it and couldn't find it. I was the guy who provided input on the catch can.
When you do the catch can you want it to be PRE-INTERCOOLER. When the oil accumulates in the intercooler it coats the inside, and makes the cooling effeciency lower.
Some of the tech stuff can take days to answer, even weeks. If you take down a thread no one can aswer it.

Lowering the intake air temperature will enable the DME to adjust spark timing and air-fuel mixture strength closer to its ideal parameters. That’s always an admirable, and often rewarding, pursuit for those of us seeking to exploit all of the horsepower for which we paid.
Minimizing PCV blow-by reduces the non-combustible ingredients contained in the intake charge. It helps to reduce deposits in the inlet manifolding, and ultimately, carbon buildup in the combustion chamber. Doing so not only reduces the likelihood of pre-ignition, but also maximizes the spark timing for the available octane. EGR introduces a minuscule amount (>2%) of inert exhaust gases to the intake charge to lower peak combustion temperatures, thereby reducing NOx and the proclivity toward detonation that would otherwise be encountered during less than WOT loads.
EGR = Exhaust Gas Recirculation
PCV = Positive Crankcase Ventilation
Where, in your attached images, did you modify the EGR system? Off highway use, of course.

I believe it's air injection rather than EGR (the hose that you pulled).... a dual vvt car doesn't need EGR. it can optimize the valve events and ignition timing to burn almost all the mixture, so it doesn't need to bring it back in to re-burn it...
