I'm in a little bit of a pickle right now. Four hours from home and my car decided it doesn't wanna run. Tried pulling out of a parking lot to head home and car just stopped dead without a cough or a sputter and white clouds were billowing out my exhaust. Got it started again and pulled into another parking lot and my first thought was head gasket but the oil and coolant are fine, however my option b tank is empty and there is no leaks. This leads me to believe that my intake manifold is cracked and letting water from the laminova cores into the engine. Somehow the motor idles fine but will not run well past 2500 rpms. Anyone have any idea what could've happened? PS I drove about 300 miles today and never had a problem til this happened. Any help would be appreciated.

 

Bump any ideas?

 

why dont u change the oil and find out..... lol

 

Oil looks fine and so does the coolant and neither of them are lower than they should be but my option b tank is empty and if it's not on the ground it's gotta go somewhere. I gotta get it loaded on a trailer and get it home so I can dig in and find out what happened

 

is your CEL light on? if so get it checked at a nearby autozone for free

 

The only code it threw was p0300 (multiple cylinder misfire)

 

Diagnostic Trouble Code (DTC) P0300 Multiple Cylinder Misfire (Catalyst Damage) hope this helps.... it may be your catalyc converter

 

If hes smoking white and his option B tank is empty then i would say its in your engine. (Your lucky it didnt hydrolock)

Pull the S/C off and the intake manifold. Maybe a core broke or some other problem.

 

My thoughts exactly about not hydro locking because that tank holds a good bit of fluid. I've got the car on a trailer and on the way home now so I can check it out. I'm guessing I'm just gonna have to buy another intake mani. Also forgot to mention in the first post that I'm getting a tapping noise coming from near on of the pulleys. Doesn't happen at idle but after about 2000 rpms you can hear it. It was doing this before the white smoke problem so I'm thinking it might just be the belt tensioner maybe but does anyone know?

 

probably belt tensioner

 

That's what I was guessing because the one I've got looks well used but I paid almost nothing for it

 

I replaced my tensioner because of the same sound. It fixed it, and good luck fixing the coolant problem

 

Ok thanks. Drumrush did you get your iat2 wiring done?

 

Since option b is for the supercharger then yes, something broke there, allowing coolant to enter your engine ...

 

Took the intake manifold off and found this wonderful site.



Turns out there's a hole in my dual pass endplate in the seat for the laminova o-ring seal and it let all the liquid pass around the end and up through the fins on the cores and into the manifold.

 

That sucks. See if you can get the vendor to replace it

 

i just now ordered my harness for the sensor. then i gotta remember to have vince send me a retune for the 2.5 bar map
