Re: Synthetic oil vs rotella t4
Dump the CCV
(crankcase vent) to the ground, instead of into the intake, and your CAC
leaks will disappear.
The "original" design of the IH/Navistar T444e was an atmospheric CC
vent. Ford added the crankcase vent to intake to meet light duty/automotive emission standards.
You can reverse the dog-house on the rocker cover (face the outlet to the rear), and hose or pipe it to the ground. This is the way Navistar did it.
My truck's been running this way for years and years...
