RE: [Chrysler300] PCV Valve on G

[John <spiers@xxxxxxxxxxxxxx>]

Hi Rich & all - 
 
I have a 1958 Chrysler Windsor parts car with a 354 poly-head V-8 with a two barrel caburetor - and there is a hose from the oil filler cap to the air filter, and metal fittings on both the oil cap & air filter housing to accomodate the hose.  It all looks factory.   Are there and 300 installations of this setup?  On this Windsor, by the way, there is no PCV valve.
 
About your conversation with a future mechanical engineer - I started out being a car buff as a young kid.  I had never known anything specific about 300 Letter Cars unitl I saw a 70s Road & Track "Salon" feature on Richard Carpenter's 300-D convertible.  I read up about 300s and discovered information about Bob Rodger, who got his mechanical engineering degree at Clarkson University (it was Clarkson College of Technology when he was there) in 1939.  A few years later, I applied to Clarkson, the only college I applied to, and was accepted there - that's where I got my mechanical engineering degree.   Though I lived on campus, I took many 100MPH+ trips on the 150 mile trip through the Adirondacks back 'n' forth from Potsdam to home in my 300-K coupe - I used every one of those 360 horses.  i wish that car had a 150MPH speedometer - several occasions, I had the needle a few clicks past 120MPH - I'm guessing 128-130MPH was close to the top end for
 that car - on Goodyear Custom Power Cushion bias ply tires yet.
 
Also, a mechanical engineering buddy of mine who I turned on to 1957-1959 Mopars (he bought a 1958 DeSoto Firesweep Sportsman two-door hardtop recently) was fascinated by the coaxial power steering design in his car - he was used to F#rd products, where there was a remote slave cylinder doing the hydraulic assist - he thought the all-in-one Mopar unit was advanced thinking, from the viewpoint of the 1950s.
 
Now I work for a firm that sells sewage pumping stations.  Our business is doing very well [insert toilet humor here].

Doesn't the PCV connect to the air cleaner on top of the carburetor? If so,
there would be no effect other than to put the nasty, oily fumes into the
little shredded wheat filter on the side of the air cleaner. I understand
the PCV could be connected to the intake manifold to see higher vacuum and
pull more fumes--I'm just not that familiar with the connection points on
all cars. My '99 Jeep PCV is connected to a header between the air cleaner
and the inlet manifold (injected engine). As I recall, PCV's act as check
valves to prevent backflow/backfire into the crankcase.

Anyone ever install a PCV on an old hemi? Would our judges deduct points
for this minor modification that would be good for the environment?

I had a long visit with a lifeguard at a car show at a swimming pool today.
He wants to be an M.E. and was really impressed with the styling and
innovative design of our 1955 C-300. He had good questions and claimed to
be an A student. He was genuinely surprised that Chrysler 300's had been
made for so many years and thought the door handles, shifter in the dash,
power seats, power steering drive, hemispherical combustion chamber design
and racing prowess to be really "cool". He even loved the rough idle. His
dad has a '65 442 needing restoration. Really made my day.

C-300'ly,

Since we are discussing stalling at low idle, I'd like to hear input from
those "in the know" about PCV (Positive Crankcase Ventilation) valves. I
recently installed one on my G, which had the road draft tube previously.
Since the device allows vacuum to pull vapors from the crankcase into the
intake manifold, doesn't that act like a vacuum leak? I must say, my car
has been more prone to stalling than it was before I installed the PCV
valve. Any thoughts on this? I don't recall seeing any different procedure
in the service manual for adjusting the carbs per se.

Bob,

I installed one on my 383 wedge last year. All I did was readjust the idle

settings at the time, and I've noticed no difference. When I chose a
valve, 
I got one from a similarly sized production engine.

The valves are designed to flow different amounts at different manifold 
vacuums, so I doubt you're having trouble that way. I'd recheck your idle 
settings.
