PCV = Positive Crankcase Ventilation meaning no matter the application, you need a great working PCV system. I notice a lot of turbo builds vent the PCV instead enclosing the system, which has benefits in itself, to promote even wearing of the piston rings which promotes a cleaner burn getting better gas mileage and power delivery. Don’t like oil leaks? Don’t change your PCV and watch how excessive crankcase pressure creates engine oil leaks. #maintenance #carrepair #mechanic #mobilemechanic #au
