Did anyone create a proper how-to web page re: valve cover stuffing?

The only illustration I was able to find in a search was Jason's three pictures at pages.sbcglobal.net/jcuadra/cam%20cover/

BTW, I'm curious why not just use multiple layers of the Fram filter material to fill up the cavity rather than primarily the copper scouring pad material. Would that much thickness of the Fram material be too restrictive?

>Why the valve cover stuffing in the first place?

I think the general idea is to create a filter within the baffle in the top of the valve cover leading to the breather hose on the driver's side of the valve cover to prevent any oil mist from leaving the engine.

The stock configuration has a hose returning to the throttle body inlet which can cause gunk to build up inside the throttle body and intake manifold.

Some people mount a little breather filter like:

roadraceengineering.com/instructions/breatherfilter/breatherfilter-parts.jpg

in place of the hose that returns to the throttle body inlet.

Others leave the hose, but route it to a catch can like:

machv.com/groilcacan.html

My understanding was that stuffing the baffle along with the use of a breather filter is the ideal option because it prevents the oil from actually leaving the valve cover, yet still provides a pressure venting effect.

This scheme allows blowby to vent to the atmosphere, defeating the PCV
system partially. Crankcase fumes used to be a major source of pollution
from cars, before PCV systems became common.

Unfortunately the stuffing I did seems not to work; I still get oil coming
out both sides of the valve cover. I will use my old DIY catch can made
from 2" PVC pipe, and add a 2nd one for the hotside of the engine.
It's made of a 2" diameter x 6" long PVC pipe with glued on end caps, a hose
barb on the side near the bottom, one on the top, and a drain (petcock) on
the bottom. The inside is stuffed with a couple of plastic scrubbing pads.

After noticing copious amounts of oil going from my valve cover to my
turbo inlet I fashioned one of those myself over the weekend. I used
1.5" pipe instead though due to space concerns. Hopefully this and the
"turbo" PCV will improve my oil burning situation. Total cost was about
$15 for the catch "can" whereas the greddy sells for like $100.
Amazing..

through (but of course you can replace the baffle material), and when the
baffles are new, VAPOR will still carry oil out. I think the catch can is the
best option, because it's easier to drain the can than it is to remove the cam

How about making a catch can and draining it back to the pan by Y-ing into
the turbo return line? Any problem with this, or are seperate lines
necessary? Don't the OEM turbo cars do this in most instances?

Check it out for us, Larry. I know the hose goes back and forth in the strut
brace, so you're probably right and I'm remembering it wrong.

The line has pressure and would just blow oil right back into it.



Maybe if you ran ut into the oil pan but even then you have oil pressure so
you may still blow oil into it.





Who knows.

The oil is under pressure up to and through the turbo, but then simply drop=

compared to the supply line - don't want any restrictions on that side. Sim=
ilarly, once the oil leaves the galleries and other pressurized parts of th=
e engine, it drops through the engine back to the sump, thus, no pressure i=
n the sump. To maintain pressure in a closed system, the volume the fluid o=

back - there can be no open areas filled with air, like a sump, or the extr=

Since the catch can is basically there to catch blowby when under boost (the
PCV being closed), which exits the cam cover at the exhaust side of the
engine, how about this: take the hose from the exh. side connection and run
it into the bottom of the catch can (where the drain plug is on Matt's
version) then use only one hose barb running from the top of the can down to
the usual intake connection spot. That way, when under boost the oily
blowby will be collected by the scrubbers and collect on the bottom as
usual, except that when the intake is under vacuum, the PCV opens and air
will flow from intake, back thru the can and will suck the oil back into the
engine, obviating the need to drain the can. All the oily stuff normally
exits the crankcase via the PCV into the intake manifold so nothing is
really changed.

When I come up with a solution that is, to me, so obvious, age and
experience tells me that I must be missing some other significant and
equally obvious reason why it wouldn't work. Am I?

Well the PCV is plumbed to the intake just like a stock car so I guess so i=
f the PCV leaks.

I guess they wanted to keep the oil vapors out of the intake tract from the=
cam breather.

So is it possible for oil vapor to get in the intake manifold via the PCV=
valve?

Apparently Mazda thought it was important to keep oil out of the intercoo=
ler.

Okay, finally got the car back and had the time to look under the hood.

The cam cover breather on the exhaust side goes into the strut brace an=
d feeds into the catch can. The output of the catch can feeds back across =
and into the air intake box. The catch can has a drain on the bottom that =
goes down into the oil pan.

Check it out for us, Larry. I know the hose goes back and forth in th=
e strut brace, so you're probably right and I'm remembering it wrong.

Isn't the separator on the hose that comes from the exhaust side =
of the cam cover, which goes through the shock tower brace?

No pressure there, nor should there be in the pan. The Mazdaspe=
ed car has an oil separator on the PCV hose, draining into a fitting on the=
pan on the passenger's side.

The line has pressure and would just blow oil right back into=
it.=20

=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20

Maybe if you ran ut into the oil pan but even then you have o=
il pressure so you may still blow oil into it.=20

How about making a catch can and draining it back to the pan =
by Y-ing into the turbo return line? Any problem with this, or are seperat=
e lines necessary? Don't the OEM turbo cars do this in most instances?
