PCV blowby question

[Jurjen]

I'm with txjeeptx.

I added a PCV valve to my flathead's draft tube(cut off tube and inserted a rubber grommet).

I find that a "refreshing" idea! Certainly worth testing it.

AMC put a different vacuum advance on the Eagles sold in high altitude areas. I don't know how it was different though. Maybe you can get one of those?

Update:
Spent $50 for the "new" PCV valve (only available on the famous auction site), problem solved, NO more oil in the air cleaner assembly or dripping out all over the floor or driveway when parked.

All emissions control crap removed, even the computer is on my workbench, everything disconnected, even the wires removed! There is no vent for fresh air to the valve cover (plugged)

Gas mileage now up to 25+ mpg, no leaks anywhere. Just turned 102k miles on the SX/4

Living in God's country where emissions are only found on livestock and my dog (and me)!!!

$50 for an OE PCV Valve???  They range from $1.00 to $2.73 at Rock Auto for the 4.2.  Are we talking about some other valve/device?

I am wondering that too , or else he meant $5 ??I have the same issue with Money Pit II , just as he describes.My PCV works,good vaccumm it seems, maybe a bit much at times ?? Idles around 5- 10 , running gets up around close to 20 I think. ( have to double check on a run tomorrow) So every few days I now open up the air cleaner and wipe it out.It has the PCV to the intake and I took another hose from where the fancy chrome breather was blowing oil all over, abd ran it into the air cleaner.The car doesn't smoke at all, just blows oil,too much pressure under the valve cover.It works like that, so it gets ran as is.I was thinking of a catch can thing,inlet on top, outlet hose connection inch or so off the bottom, stuff it with media to capture the oil out of the vapors and let it settle.

You -without thatelectri check thing correct before you go to manifold vac correct.

My apologies.  I must have missed the first part of this thread.  I will have to read more.

So keep us updated on how well this new PVC valve is working, also can you post some pictures of your engine, I'd like to see how you plugged the air inlet.

What Rita, said.  I am interested in this for the Eagle.

I just read their site. I gotta get one for the AMC and Studebaker. The low and high RPM there's really no where for the pressure to go but out the oil filler cap and the breather tube. This looks like a solution which does what a modern PCV should have been designed to do.
 $47 worth not having to scrub the block and air cleaner all the time.

Rita--and others interested:

This is called a envalve, go to their website on my first post which I did not get much response, usually "rebuild the engine"!!
$50 is much less and worth a try so I did it!
It replaces the oem pcv, made of some type of plastic, hooks up exactly as the oem in the valve cover and hose to carb.
The original "fresh air intake" hose is cut to about 1" and plugged with included tapered plug (be sure to use a hose clamp).
This was the last step in engine/emissions/ignition mods.
There are NO leaks anywhere,valve cover,air cleaner housing,rear main--nowhere!!!
@ 102k miles I am amused by the constant complaints about mileage, poor performance, etc. with the 258, I can break any speed limit in Colorado at high altitude and still get 25+ mpg, city and highway combined
This is with the STOCK BBD carb,all emissions removed @ 6000 to 11,000 ft altitude, I am well pleased with the 83 SX/4!!
This is NOT a Ferrari, just a fun little car, just happens to have 4wd!

Well , that's enough said for me, I am going to try one.I was thinking though,if the original is too small, why not just run a line direct without a PCV ???or "T" the breather into the line between the PCV and manifold?So both lines go into the manifold.

i find it funny how many people tell me i need a new car just because it's an AMC. that's when i tell them that the engine in my car is the same one used in the 90's jeep cherokee that they're driving just that theirs is fuel injected with a different head. oh and i've had eagle eyes up to 120mph.

[IowaEagle]

Make them feel really bad and tell them its the same engine as found in 1964 Ramblers.
