Breath, breath in the air.

Probably more like exhale. The hole for the breather vent on the stock rocker cover, is 1 7/16. The tube from this vent goes to the base oft the new Edelbrock carb. The new rocker covers, 495 I think, have a hole that is 1 1/4. None of the Dodge breather units fit. But, Edelbrock has breather units, but with no fitting for the tube. They are also chrome.
Other places make a 1 1/4 breather unit, with the tube attaching fitting.
So, do I use the non tube unit, or the tube to the carb unit. 77 318.
The 540 engine I looked at last weekend, had both rocker cover tubes, going to a box and a small air filter thing. Not to the carb. I suspect the fumes from the engine to the carb, are part of the cleaner air idea.
I may be slow to reply, we are heading the ocean tomorrow, loaded with camping and fishing stuff.

The 540 probably had a oil reclamation device. You need a gromet for a PCV valve to vent to intake system on the engine, especially for a street engine. The opposite valve cover needs a screened breather for intake of air.

Get a reducer fitting for the hose and splice the hose.

One valve cover has the PCV with a hose to the carb base for vacuum, and the other has a breather w/o nipple or with nipple to the air cleaner. The carb via the PCV valve has to draw air from one side, thru the crankcase, and out of the other side. You cannot expect a hose from the carb to the breather to do anything at all.

Thank you all.
The PCV valve is in the left hand rocker cover. The hose from the RH cover is in place to the carb, without the breather fitting. Spliced and made to work. I will get the non Edelbrock breather that fits these rocker covers.
