Default wastgate leaking fluid?

ive been having a slight problem with not getting over a half bar since the start of the winter... i was told this was due to the colder air... but now its summer...
i was just downstairs, cars been sitting overnight... i start it up.. roll down the windows and pop open the hood because ive been constantly thinking about this.
i set myself over the turbo/downpipe and listened and looked for anything.... nothing i could see was wrong or heard wrong... i gave it a little gas and was staring at the wastegate where it connected to the turbo and noticed it move..
i learned (if at all correctly) that you can have problems with 7psi due to a bad boost solenoid or if there was a hole in one of the vacuum lines.. so i inspected those as well.. they are perfect...
as i gave it some gas a few times, i noticed fresh wetness around the part where the wastegate comes out of the turbo.. then i noticed a little coolant (maybe?) spurt ontop of the connector to the arm.
so uhh... help?
i mean, do i need to tighten down the wastegate some? i noticed wastegate flutter possibly? a very faint tapping when i decelerate.. very rapid as well.. or possibly this is just normal engine noise... i have accute hearing and i know the sounds of my engine from 120 miles til current... and this isnt exactly a normal sound as to what im used to.... anyway.. thanks in advance

also.. i have done an up/down pipe swap (helix) and a typhoon short intake (read that it maintained the same air flow dimentions as the stock air box) i did NOT remove the turbo to do the up or down pipe installs. so i didnt mess with the turbo or tubes connected to it.

wow, where to begin.

1) wastegates have no fluid associated with them, they are a vacuum system, so it's all air, if there is liquid in your wastegate then that is bad news.

2) your wastegate should not move at all when the car is parked, even if you are revving the pi$$ out of it. Boost is not made until the car is "under load" therefore the wastegate should not move when the car is parked

3) if you are seeing fluid spurt up onto where the wastegate arm attaches to the turbine housing that could be a larger problem, like a cracked waterpassage in the turbo.

now for the questions:

1) how many mile son the turbo?
2) are you hard on the car (be honest)
3) are you getting puddles on the floor
a) coolant?
b) oil?
4) are you burning or using any oil and if so how much?

I'll check back then

ahhh lets go with the questions....
1. im the only owner... got it at 120mi now its at 19,000
2. ive never been to a racetrack.. i enjoy a spirited ride and i do enjoy pushing my car occasionally..
3. puddles? none that ive seen...
a. coolant needs to be changed from the winter..
b. oil i change religously every 3-4k mi
4. burning oil? not in the least... i have de-catted up and down, still havin the third cat.

i can take pictures of it tomorow morning or even record a few short videos (which i will host myself)...

to add to this... when its been running (obviously) whatever sort of fluid vaporizes right after the engine warms up... theres ahh.. it looks like salt on the brim of a hat after it dries out... yanno... a hot day... you sweat alot... theres a white residue on the brim the next morning.... i just got a cel a few days ago.. but the engine light comes on and turns off so ahh... its still under warranty (18k mi) so i think its time i took it in for a looksee.....
i know some mods can cause more damage then they are worth so ahh.....
ive never had an atmospheric bov, strictly stock.....
i checked out my cai tonite, and it was a little dirty, id assume due to the oil on the KnN filter
i have a typhoon intake, helix up pipe and down pipe without catalytic converters.....
i have yet to get an ecu for the car unfortunately otherwise i would have more data for everyone. ill have the pictures by noon est tomorow :\ hopefully when i go down there tomorow there wont be any fluid and this post will just vanish......
but as i said... im still only getting half boost (as it reads on the oem boost gauge) i even took the gauge off and checked it out...seemed to be operating fine...
can i take the boost gauge and a section of tubing and hook it up to the turbo almost directly? to see if there is something in the line? (i dont know how or why there would be but the car's sounds havent changed noticibly since ive added the previous mods) also, would waste gate flutter affect a turbo as greatly as to cut its boost pressure in half?
ive also read about bad stock manual boost solinoids... that if they are bad you shouldnt get more than 7psi (.5bar) or if you dont have a vac line hooked up, you wont get boost either....


sorry if that was sort of rambling, but this is various info ive picked up racking my brain about this problem... i think im just gunna bite the bullet and call up a dealership on tuesday. if this is a problem like you stated... then i cant wait any longer, and i have to take it in....

i hope this helps both you and i

I wouldn't be expecting a whole lot of help from the dealer with your turbo unless they are pretty mod-friendly...

well why do you say that? it would be more helpful if you gave some specifics... to the best of my knowlege (hours on this wonderful forum, a wrench and more than half a brain) that none of these mods would cause a problem such as this... i baby my car compared to some of the horror stories ive read around here...
and please do correct me if im wrong.. id like to know what im getting myself into if ive done something wrong..

....and if you take your car to the dealer with those mods, you will likely get grilled and denied any engine warranty work

I thought I did by quoting very specific things that you said...

the up-pipe and downpipe both have a large impact on how the turbo functions - they both also require that you unbolt things from the turbo, potentially damaging oil/coolant lines, etc. - generally speaking, a dealer can only really deny coverage if the mods you made could have caused the problem... you changed pretty much everything (short of the boost control solenoid) which impacts the turbo, plus could have potentially messed things up during the install so them arriving at the conclusion that you caused whatever is wrong really isn't much of a stretch - esp. if the dealership isn't mod-friendly.

By all means, give it a try and see what the dealer says, I just wouldn't be expecting a miracle (esp. if the SOA rep happens to be in town and see it...)

I am unclear, how did you see fluid coming out of your wastegate? around the wastegate actuator arm?

I know I saw liquid leaving my downpipe before I had it re-tigged, and it was just unburnm fuel/vapor... which is pretty damn common for a cold engine to have in its exhaust stream.

The dealer is going to kill you with all those mods. The white stuff on the wastegate sounds like coolant, when coolant dries it leaves a residue similar to what you are talking about. I'm really not sure what to say without looking at it. The CEL is interesting also, perhaps you have an exhaust leak at the downpipe, condensation would shoot out and leave a residue, also the CEL could be attributed to the intake, I've seen cars have an on/off CEL when running an aftermarket intake. Sorry I'm not more help but at this point you need to have someone look at it.....post in your local forum and see if anyone can meet up with you. If your in central PA (longshot) I would be glad to help out....

ahh thanks for the responses.... i checked it out again today and there was nothing... i cleaned off some of the residue and there is none where i cleaned it.. there was no fluid either and no cel... i think it was some random thing that i just happened to catch... ill be keeping an eye on it...
but ahh... im still left with the issue of only getting 7psi of boost... where can i hook the boost gauge in the engine bay?

the OEM location at the BOV is probably the best part. If you are getting only 7PSI there is a chance that the factory boost control had taken a $hit. I think the wastegate is set at 7PSI on the stock turbo. Weird part is that I think you should get a steady CEL if that solenoid failed...

Keep in mind that when the engine is cold (and the turbo) a lot of moisture gets condensed out of the exhaust. If you start a cold car and just idle it for a couple of minutes and then drop the down pipe the outlet of the turbo will be completely wet with condensation. I suspect that is what you were seeing.

you'll only get a cel if it fails electrically.

it can also fail mechanically and pneumatically.
