no boost
 

i have about 20 vacuum at idle then when i drive it i put it in 2nd and put my foot on the throttle no boost it stays at 2 vacuum closest it got was 0... then in 3rd the same thing and it is making a knocking noise im not sure wat it is i think it might be my wastegate or something? and after driving for a minute my car smells i think it is my turbo...its like a smell burnt oil smell except really bad and last night my turbo was smoking... my plugs are white at the ends so im guessing im running to lean

Re: no boost
 

Get a wide band and get it tuned,
Check your waste gate if its stuck open
Do a charge pipe leak test

Re: no boost
 

Ya your wastegate isnt closing or u have a boost leak. Check your charge pipes with some soapy water. Knocking is not a sound you want to hear. It would really suck to blow your motor b4 u even hit boost wouldn't it. There is a leak somewere find it and you will be good. Tune it before you hit boost white plugs =no good!

Re: no boost
 

how do i test it with soap what do i do and for my wastegate i took off the vac hose i know its closed shut.... still no boost then i got a cel ..

Re: no boost
 

Put soapy water in a spray bottle, pressurize your charge pipes and spray suspected possible leaks (mostly on couplers). Taking off the vac hose doesn't mean that your wastegate is fully closed.
Are you using an internal w.g? if so, get a "helper" spring to help shut it completely. Is it a new turbo?

Re: no boost
 

it has a internal wastegate off and its a chrysler t3 not rebuilt but it had barely any shaft play the fins on the compressor side werent chipped or anything...so i just start my car and let it idle spray soap on it see if it bubbles?>

Re: no boost
 

NO, you have to have pressure in you pipes for the soap to work. If you just idle it will such the water into to intake system. A better idea is to find someone or take up the habit of smoking, Start the car in an area where there is no wind, and exhall the smoke around the charge pipes and see where is it drawn too.

FYI, You rad fan must be off also.

Re: no boost
 

i idled it and sprayed soapy water all over my charge pipes and in one spot it made bubbles but i dont see how it is leaking..can i also not have boost somehow by using mesh as my pre-intake i read on here that people used cloth and they didnt get any boost
