#84552, "Exhaust pressure?"


          

Okay here is the deal. Probably a simple answer...
I have a vac leak and thats prolly why I have a shitty idle because the map is telling ecu to dump more gas in the motor, but anyway besides the fact of that, it seems like the pressure or whatever you want to call it coming out the back of exhaust is like real strong. i mean, i put my hand to it and it can actually like sway my hand back a little bit. im puffing a little bit of white smoke, i think its from it being kinda cold which is normal but when it gets to operating temp, it still puffs a little bit. i know its not the HG since its brand new, everything was torqued right and no oil mixed with water. now, i read on an article on the web, that having a vac leak could puff white smoke?? (i will post the article below) and that also build up in oil will puff white smoke too. now, my drainline for the turbo is kinda long and might not be draining right so i need to fix that asap before i start driving her around, but if the drainline is getting clogged a little bit, could cause it to puff? so i guess what im asking is: 1) can the buildup or a vac leak cause white puffing? 2) should the pressure coming out my exhaust be like this? i dont remember if it was like this last year or not. im using the tanabe racing medalion 3" catback with testpipe and 2.5" star d/p. thanks for answers, here is the article i read:

Damn man, there is this thing called a space bar not to mention grammer for easier reading. I'm no English major, and English is not my primary language according to LAUSD... but I cleaned up your question in hopes of someone can comprehend and provide a response.


"Okay here is the deal. Probably a simple answer...
I have a vaccum leak which I think is the cause of my shitty idle. This Vaccum leak is causing the MAP sensor to tell the ECU to dump more fuel into the motor.

I noticed the exhaust gas coming out of my tail pipe is "strong." Meaning when I place my hand in the exhaust stream it is able to push my hand back a little bit.

The car is puffing a little bit of white smoke, which I believe is due to the cold temperature (which is normal), however when it gets to operating temp, it still puffs a bit.

I ruled out the HG since it is brand new, and everything to torqued to spec. There are no evidence of oil mixing with coolant/water.

I recently read an article on the WEB, that described how a vaccum leak can be one of the causes for a car to puff white smoke and that a build up in oil (pressure??? ) will also do the same. I suspect my turbo drain line is too long and might not be draining properly, hence I will need to fix ASAP before I start driving.

My question is if the drain line is clogged a little bit, can this cause my vehicle to puff? If so: 1) can the buildup or a vac leak cause white puffing? 2) should the pressure coming out my exhaust be like this?

I do not recall the vehicle acting like this last year.

Additional information on my current set up is: 2.5" Star DP, test pipe, and 3" Tanabe Racing Medalion catback.

Thanks for answers, here is the article that I read.
