Engine Serial Number Decode and Crankcase Ventilation

Sweet! That makes the retrofit much easier.

Oh, one other thing: the 170 wants a PCV valve calibrated differently from the larger Chrysler engines, including the bigger Slant-6s. Use a Chrysler part № 4315 405.

Hi Dan. Was reading the Engine Serial Number Decode and Crankcase Ventilation thread....I have my stock 170 and am looking to convert to a PCV from the draft tube...I have changed out the base of the carb so I have a PCV port. Can you tell me what PCV I need...I think the older engines are different. Thanks.
