Crankcase vent

[Boater 64]

Can someone tell me why the 6.5 do not use the crankcase vent baffle .I just removed the front timing cover on this 6.5 to replace the timing chain and noticed that there was no crankcase vent baffle .Are they not used on the 6.5 or was it left out my mistake . All the 6.2 i have worked on have this baffle. thanks for yoyr help .

Earlier years of the 6.2L had CDR draw thru the oil filler tube, requiring a baffle.

Any 6.2\6.5 , with CDR drawing thru the passenger-side valve cover, does not require the baffle - the oil filler tube is just an oil filler tube.
