I recently did the dual pass with option b and had the car running the other day to find the supercharger pulley was grinding on the snout. I took the snout to be machined down and spun freely. Well after putting the car back together i let it run today and let it heat up and realized the cars idle was all over and then thick white smoke was coming from the exhaust. I shut it off instantly, i said maybe its just some oil or somethig inside the exhaust when i took it off to change the gaskets. And car trys to start but wont fully turn over now. The starter just keeps turning it and someimes the car gets the point where its just about to turn over but doesnt.

Is coolant getting into my motor? I think from when i did the dual pass maybe a gaske in there wasnt put in good

 

I Think your right. Something in the Intake manifold from when you did the Dual pass is probably leaking into your intake.

 

white smoke means coolant. you got a intercooling leak somewhere just replace any and every gasket and seal. when i did mine i had a hard time reusing the dual pass map gasket.

 

Fixed the problem today. One of the gaskets and the little rings werent siting right on one of the cores. The intake manifold was half full of coolant!!! I flushed it all out cleaned it up and re installed all the cores and had the car run for a while to burn off the rest of the coolant inside the motor and what not. But my cars idling funny. It always had idled funny and i did alot to try and fix it, no codes are being thrown, i have new gaskets for everything intake mani, supercharger, TB and i also put new vacuum hoses. I changed both O2 sensors. My afrs r jumpig between 14 and 16. And my idle is all over and sometimes stalls on its own. The boost gauge will go up and down as well depending on how the idle goes. I also have no spark plugs. And my throttle body is clean. What else is there?

 

I think this could be your problem!

But then, how is your engine running at all?

Or did you mean "NEW" spark plugs?

Becareful though, Coolant doesn't compress like air does. So the engine may be damaged if it sucks up too much coolant.

 

I have new sprak plugs. The idle problem was going on even before the coolant issue.

I didnt mean to put "no" i meant new.

 

Ive been seein more and more Idle problems lately..and noone has given a answer..Im in for a answer as my car does the same..

 

My jdle is really horrible!! Like it wont even run without idling all over the place. If your lucky maybe itll idle normal but thats very rare
