PCV Breathers vs. closed system?

[Tom]

Are there any advantages to going with Breathers vs. using the closed system?

A lot of people seem to be putting catch cans on their s197s, but I don't see the point when you can just block off the intake ports and put breathers on.

The biggest issue with just putting breathers on is the oil vapor in the air traveling through the breathers will eventually saturate the filter and start running down your engine, the catch can catches this oil instead and helps keep your engine bay cleaner. thats about it really imho

I cant stress enough the need for pcv! the PCV valve helps to maintain a good ring seal, keeps gaskets sealed tight, and helps reduce windage in the crankscase.. If you are getting oil in the intake from a pcv valve you will have to get a oil separtor and run it inline and check it periodically.

i want to say those are more like accumulator tanks to catch oil that may enter the intake or run down the side of the motor.

X2.....

Street cars need PCV valves. An oil seperator (or catch can) run INLINE is the best. The oil vapors will drop out of the air stream while the crankcase is still evacuated under vacuum conditions.

You are right, that is pretty much exactly what they are, but many people call them an oil catch can. At least idiots like me who drive these retarded crankcase pressure having, dipstick launching, machines that break down weekly LOL

:tea:. been saying this samething for years

The PCV on the s197 is integrated into the valve cover (it has baffles). Would running remote breathers be ok with it setup like that, or is it still better to run a accumulator?

I read a thread on s197forums and thought it was interesting.

I have an oil separator inline on mine, but the oil just goes right through it.

I had the same experience. It would catch maybe 1/2" or so then never any more. I could dump the 1/2" or so every once in a while and after a while it would fill back to that level but never any more. I plan on putting a bigger reservoir in line.

Is the oil seperator baffled? some people will put some coarse steel wool inside them as well if there is a way to open them. If theres nothing there to actually make the oil condense back into droplets the vapor will still get right through. I learned this the hard way.

Yeah its got a white foam style baffle.

Hmm, that's strange then. Is it a vented can or is it a sealed style?

Its sealed like one from a compressor.
