I use breathers on my street car. I also change the oil & filter at 1k, without pcv ,moisture can build up, so far I have not seen any when I adjust the valves.

I use two breather on my street and strip car too... Pcv reintroduce oil fumes into the engine and I think it's not the best octane booster.. I agree pcv is good for everyday car

You should use a PCV on a street car. I do, always Moisture will condensate in your motor when sitting over night, the heat from the motor oil warming up the oil will help turn that moisture into steam (hot air rises)which the PCV will suck out removing it from the oil helping keep the oil in better, useable condition

Pretty much every engine up to the early 60s emissions era did not use them. Just had a pipe that turned down from a stand pipe on the valve cover, the old push on covers, vented to air. Either way engine must be vented. A good barometer on how the engine is lasting, no blow by, good, a lot, time for overhaul.

Remember back then how at red lights the air would fill with blow by from some of the high mileage (over 50,000) cars waiting for green?

The better PCV do need a minimum, how much I don't, vacuum to keep them open. The cheaper ones will stay open most of the time when the motor is running All of them I've seen and cleaned have a check ball and spring to close the ball when the motor is not running, not all of them will seal up when not held open by vacuum

So a pcv valve on one side and a breather on the other side would be a good set up for the street? Yes. Ron

I run 2 breathers on my 440 The M1 and Dominator have no provisions for vacuum.Been like that for at least 15 years My son also ran 2 breathers on the 62 300 when he had it.Never a problem with it either and it had the OE motor.We just replace the draft tube when he put the cam in and drove thousands of miles.Rocky
