The boots to the inter cooler get oil soaked from the PVC system and will slip --check the boots and clamps.

If these trucks have no vacuum then how is it getting to the heaters to blow up or cause damage to the internal parts? Not trying to be smart, but either it will suck it in or it wont.

BTW it will work.
