On the MAF Harness, is that not an additional single black wire taped to it? Might just be an optical illusion.
dang, good eyes.

Tb hose with the flaps taken off, it keeps sliding out from tb (not leaking anymore).
I was thinking about putting on some hair spray around the inside of the hose?
Thought I'd ask the experts first.

Hello there,
This quick writeup is hopefully going to help those who are unfamiliar with their engine bay help find and fix the more simple vacuum and pressure/boost leaks most common with these cars.
These pictures will be used as a loose reference for those searching to see a physical picture of what is described by most members that could be causes of leaks and struggles.
Intake/Vac leaks are one of the biggest headaches when tuning so the opportunity to go through the engine bay and check things out is always a plus.
The biggest thing to make sure when reading this is it assumes you have checked to make sure all worm gear clamps and such are tightened down at the airbox,turbo inlet, top mounted intercooler coupler to throttle body and to intercooler. These are simple things some people don't check first and causes a bunch of headaches for them.
This is a video showing what kind of leaks are possible and then pictures breaking down specific areas

1. This first picture is showing the turbo's wastegate hose *silver bell*, The turbo inlet *bigger black hose connected to turbo*, The turbo nipple hose and the turbo to intercooler mounting flange. These areas are prone to leak if the intercooler is not mounted properly and flush, The hoses are not seated on the hose barbs and if the turbo inlet has been chewed away by the clamp being tightened too much/not enough or just adjusted too many times because of age. If its oily and looks like rubber is coming through the worm gears section of the clamp its probably leaking.

2. This next picture is part of the next picture as well when it comes to descriptions. These intercoolers can leak from the plastic end tanks once they have aged OR are pushed at higher boost levels. The aluminum "fingers" start to fold up and the black plastic end tank starts to move away from the core which causes leaks. This is pointing at the underside of the core to explain it can leak from the bottom as well as the top.

3.This picture shows what was discussed in the last picture which is leaks at the intercooler to end take mounting area. These "fingers" can start to fold up over time because of age or being ran at higher boost levels and cause the end tank to separate from the core. If you look closely you can see where oil is escaping in the boost vapor and actually causing a spot where the intercooler is leaking. This is a common issue with this models intercooler.

4. This next picture is on the drivers side of the intake manifold between the two intake manifold runners. This is another vac line that can pop off so its good to check and ziptie. This also points at the area you might see an intake manifold gasket or anything leaking related to the tgv assemblies.

5. There is a lot going on in this area so it needs to be checked and ziptied/clamped as best as possible. This is at the turbo inlet area to the left side of the alternator. This is where the Stock electronic boost controller mounts and there are a lot of lines in this area.

6. This next pic can be a little confusing but most of the arrows are pointing toward the lines coming to and from the blow off valve. These need to be free of obstruction and connected tightly. Also make sure the gasket is in place on the bov if equipped. The arrow pointing under the intercooler is actually supposed to be pointed at the throttle body coupler and the fact that sometimes to get to the clamp closest to the throttle body you may have to go from under the cooler. There is a plastic sleeve on the stock throttle body hose that's prone to leak and can cause strange high pitched sounds when pinched open under boost. This has been said to be removed without issue but some say its very hard to get it sealed without it because of the design.

7. This next pic was used from a google search as I couldn't find a good lighting pic to demonstrate its location best. This is conneted right near the center of the rear of the intake manifold right under the top mounted intercooler. Its very hard to get to with the intercooler in place but is well known for popping off and causing people hassles. This can be ziptied or replaced with a barbed T fitting *one is supplied by a forum vendor turkeylord*.

This writeup is designed to help and the more comments and such people can provide will help others in their searches for leaks and hassles. Always keep in mind the age of the vehicles and that vacuum lines can crack or wear through with contact so the leak may not always be at one end of the hose either.
Hope this helps and bump it up to the top for others if you like the info

Proud to say I did all those mentioned... Still leaking somewhere... hahaha -.-
Most recent was that farting tb hose that popped off.

Guys, I had this issue every time the weather got cold. People suggested the peddle sensor, so I sprayed the shit out it with electric contact cleaner.
That was year and a 1/2 ago. Clean that connection behind the peddle, it worked for me.

Just did this while going stage 2... wow the oem gasket inside is about 1/2 as tall...
No more shuttering at stoplight and no shuttering at cold-start (today was cold in NYC).
Can't 100% say it was the gaskets, maybe the ots stage 2 map? but whatever it was, problem solved.
No greater joy than coming to a stop and not getting hiccups!

Got 207,XXX on my 2005 sedan.
All I have had to do so far, knock on wood, is one O2 sensor and both rear wheel bearings. Thats it.
*i have a non-turbo, but figured ya'll would appreciate the mileage and reliability good news*
You had me speechless until the last line. props nonetheless

I have the 5EAT, been changing trans with OEM fluid and diff's on regular basis with Royal Purple. The trans still shifts smoothly.

Damn dude, so much respect for keeping this going!
Man, where are you in Queens? I'd love to get a glimpse of this car one day.
If I ever saw this on the LIE or something, I'd probably fanboy pretty hard.
