Ralph, Thanks for the advice on keeping it stock on the oil flow. I'll probably keep it just the way it is. I don't have a road tube to worry about, since it has the PCV system.
Do the older PCV valves need changing like the new ones? Are they even available anymore? This one is metal and looks like its been on there a long time.
I still need a fan blade. Can the 235 fan blade be used without disastrous consequences?
Kimo, keep your name as is. But depending on how you drive your truck, you could change it to "Kimo-Kazi"
