03 5.4. I got a pinhole leak shooting cooling out the back of the metal tube under the intake. Ive had lean codes for awhile as well and trouble keeping her running in the cold, so I am replacing the intake. I got the coolant bypass tube off after fighting those studs on the back for hours. Here's my question. Do I go back OEM metal tube, actually dorman is what available in a timely fashion near me, or rubber hose mod it and run it out front of the intake. I have the heated PCv valve if that makes a difference. The expy is no beauty queen I want reliability and ease of working on. Thanks for your thoughts.
