Engine Serial Number Decode and Crankcase Ventilation

Poor idea to run without PCV, if for no other reason than you'll have to constantly deal with the wretched stink of crankcase fumes wherever and whenever you drive. The firewalls of these cars are full of paths for underhood air (and fumes) to sail into the passenger compartment, and even if the firewall itself were to be magically sealed up, the hood-to-cowl seal isn't anywhere near complete; you'd still have crankcase fumes flying right into the car via the cowl air intake.

Job worth doing = job worth doing right.
