I have an 03 Ram with the Hemi, and what I believe to be an AEM cold air intake. I'm having an issue with moisture getting into the intake, and PCV system. Anyone else experienced this problem? Truck runs fine otherwise, and no I'm not losing coolant anywhere, this is straight water.

 

How much water? Some condensation is pretty normal......

 

Fairly decent amount, only happens on these really cold winter days we have here sometimes in MN. Freezes up my PCV valve solid, and I've found ice accumulating around the throttle body as well; so much one time, it built up a small ice dam on the intake side of the throttle body so the throttle plate couldn't move!

 

That's kinda bizarre...... Don't think I've heard of that one before...... Is any coolant routed thru the throttle body, to prevent that??

 

Nope, nothing. I took the liberty of insulating the intake tube, AND the 2+ feet of breather hose that goes from the intake tube to the oil filler. Guess we'll see if that helps keep it warmer/drier.

 

2+ feet of breather hose! Doesn't that seem sort of long? Pull your oil cap and look at it and check for moisture in the cap I noticed my 04 Hemi had lots of moisture on top of the cap so I removed the tube from going back into the intake and put a little filter to catch some of the blowby. Did the insolation help any?
