I am about 2 months from start up and currently checking the route the vacuum hoses.
The project is a T-Bucket with a 4.6 DOHC from a 1993 Mark VIII. I will be making my own charcoal canister from an extra coolant catch can. This schematic is easy to understand. The one that runs the IMRC however has stumped me because of WHT acronym. Does anyone know what that means? I will be doing an EGR delete anyway so is this a moot point?
Thanks in advance.
