Lol but I did have plenty of customers with messy engines.... they used to look at me like I was crazy when I'd say they need a new PCV... I think they thought I was making it up....
Yes, and over on the Dodge Neon Forum, I have to keep correcting all the kids that put chrome breather filters on in replace of their PCV, because that is so much better than breathing those fumes into the engine.
Hello, if you suck the water vapor and corrosive fumes out of the crankcase intead of letting them linger, your oil will lasts twice as long and stays twice as clean, the PCV easily doubles the life the of your oil and likely your motor.
A bad PCV with conventional oil for a couple of tens of thousands of miles, and you'll likely have deposits and sludge forming all in the motor.
I also have friends look at me crazy when they see me spraying down the motor with Simple Green and hosing it all out. Wire Insulation, Seals, hoses and plastic lasts a whole lot longer when they are NOT soaking in salts, fluids, chemicals and grime. Plus, when you do get a leak, it makes it so much easier to spot the source on a clean motor, viced a massively gunked up motor.
