Default HELP. Smokin turbo/BoV leak

so after 3 weeks of putting on parts and such i start my car today. it is idling like normal before i put on the turbo and its fluctuating. but whats really bothering me is smoke is coming from my turbo. i did spill oil on the turbo but its freakin my out cause it doesnt really smell like oil. also my BoV is leaking air from the VTA port. its a greddy BoV and i teed the nipple thats -- like that to the throttle body and the one that angle down / not quite like that but at a 45* i teed it into the compresser/wastegate. its a stock greddy kit and i removed the AFM and its not reading the air temperature help help help.

I have no wheels

You know the greddy blow off valve has 2 nipples to put line on and 1 port where air vents from it. the part where air comes out of it is leaking air. i dont think that is normal as leaking vaccume will cause uneven running. also i have a oil leak that i am attending to. that will be fixed the only thing that concerns me is the BoV leaking air. i dont think it is suppose to be doing that

bottom smaller nipple should be on a line off the turbo, pre TB.

top larger port hsould be POST TB, so the nipples off the manifold.

it will most likely leak at idle, but it doesnt matter now.

no intake temp? did you install the new intake temp sensor correctly?

smoke is normal on first startup, gotta burn off all that ****.

i hooked up the BoV right. and i i believe i hooked up the IAT relocator right. i lost the things that go into the AFM bracket so i snipped the clip off and just used butt connectors on the 2 end ones. the car starts so i believe its working. just not giving me a reading of what it is

well. what are you using for the intake temps?

a GM sensor?

did you wire that to the MS, or did you hope it had built in bluetooth and picked up the signal automatically?

ok so you wired the GM intake sensor to the AFM harness and then grounded the other correct?

did you built this MS?

i cut off the AFM harness and spliced the 2 wires that the directions told me to connect with via prongs. but i lost the prongs and figured this would work. i ddint wire them wrong because they both have 0 polarity and you can put either or to either wire. no ground cause no third hole for it

so now after a while i got the car started and its leaning out hard. i cant even put it in gear and go up a hill or it will cut out. if the IAT was not hooked up would thecar start?. it seems to run fine while the engine is cool but once it warms up i cant put any gas on the pedal or the car will want to die. i cut my harness to splice in my AEM eugo wideband gauge and its not reading on the megasquirt could this cause my lean problems?

should i start a new post in the megasquirt section?
