I have a skunk2 throttle body on a Skunk2 Inatke manifold and a AEMShort Ram intake on my b18. Whenever I rev the motor, coolent gets suck from the line on top of the throttle body (that runs to the ICV) into the throttle body itself. SO I'm sucking coolent into the engine, which everyone knows can blow the motor. I do run larger hoses for the coolent, I'm wondering if there is a way to stop this from happening or is it suppose to do that?

 

Uhhh...there's no coolant lines on TOP of the throttle body. There are two on the bottom, unless you mean the two coolant lines on your IACV that's mounted on the backside of the intake manifold

 

Take a pic we'll be able to help a lot more.

 

uh-oh. sounds like he may have ran a coolant hose to a vacuum port

 

Yep, that's what I'm thinking. When he looked at it and saw the idle screw next to it, he must have thought it's for the IACV

 

So he connected it to the evap vac plug ? then must have connected the coolant line to the charcoal cannister. that's my guess it's the only vac port on the top of the TB.

 

Well, its the line running from the IACV. I have it connected to the port at the top of the tb. The lines might be messed up, I just recently got the car and the there was a bunch of hoses connected to the wrong place.

 

yup that's wrong. it's supposed to go underneath the throttle body and the line that's supposed to go on top should lead to the charcoal cannister.

 

okay, thanks guys. I think I figured out the line confussion. I'll move them around in the morning and let you know how it goes
