Guys,
I have 30k miles on my truck, no catch can, no intake cleaning ever done.
I average 15 mpg with mixed driving through the lifetime of the truck (6speed crew cab, 33" MT's, 3.43 gearing, leveled, black widow exhaust, airraid MIT).
The best I've ever seen is 18MPG, MAYBE 20MPG, even new on stock tires and suspension.
my questions are;
1) Is it too late for a catch can, is the damage done?
2) What can I say to the dealer to get them to look at the intake valves for suspected buildup?
3) Is it too late for intake cleaner on my truck? What are the hazards vs rewards?
Any responses are appreciated. I'm scared shitless now after reading the extreme positive and negative stories around the intake buildup.
