Filling up oil catch tank on track.


I ment remove the core plug and fit a drain back there. Im running removed pcv with vented rocker cover, but im na. Murrays suggestion might work, less likely to push oil oit the baffled rocker cover
 
Go-autoworks do a port the replaces the bung so you can drain back...

So essentially with this D on your diagram is also and AN fitting for draining

This also provides a 3rd point for extra breathing

It does work, i have a boosted crx and it never pushes oil into the can:nice:
 
I'll give this a go, cheers!
 
Also your breather pipe diameter out the top of your can looks very small. If your having an an fitting welded on the bottom you might as well have a bigger neck welded on the top - mine is 38mm.

Else it will act as a restriction to your breathing system.
 
I'll probably get a new can with more ports anyway. So I can attach all the breathers to one can.
 
Nice sizeable filter on it!
Will see if I can get that tank. Seen as I have all the ports and clips etc already.
 
So here's what I'm looking to do.
Two extra ports from valve cover going to two extra ports I'm having welded on my can.
I'm then going to use port B as a drain back from the bottom of the can.
Then having a 44mm pit bike airfilter put on top of the can to help clear the pressure.
Anyone know any reason why this isn't the right way to go?
Can I use port b for drain back or is this not a good idea?
 
Sounds better, but i would just block of B all together. No need to have a drain back.
 
I can do that first and see what happens. Can't see it filling the can up with the extra ports in there.
 
If not already noted, "B" and "C" should be the return ports.
Install or buy a rocker cover with one that has 2 ports to vent over to the catch can. Rocker cover ports should be on the front of B series, gated is possible to prevent oil from splashing into the port.

On the K series I only ran 2 ports from the rear of the valve cover with no return lines, filled up 1/2 QT with dark oil for a full track day. Its not really oil, its sludge. The vapor inside the valve cover condensing into this sludge.

On both B and K series, lower revs keep this from happening as much...

Use "B" for drain back. :) or "C" they both go to the oil pan directly.
 
This is quite interesting:

The breather helps ventilate the crankcase. It surprises me how many people mistakenly think the air blows out into the intake so they think removing it will give them more power. Talk about misinformed. Mike D posted a good write up on this before:


Here's the stock PCV diagram from the Helms manual. on the left is a cutaway view of the engine. on the right is a cutaway view of the stock intake. In the middle are the separate breather circuit and the PCV valve circuit:

all you have to learn is how the fresh air cicuit flows (follow the open white arrow) and how the crankcase vapor (with oil vapors in it ) circuit flows (follow the black arrows). Notice which circuit flows to the valve cover (on top of the engine on the left)....it's NOT the crankcase vapors. When you add a breather, you remove the line from the intake to the valve cover.


The honda crankcase breather is a POSITIVE pressure ventilation system.The air from the intake blows into the valve cover. It is NOT a negative pressure ventilation system...it does NOT suck air from the valvecover to the intake.

Breathers remove the source of positive ventilation that repressurizes the POSTIVE CRANKCASE VENTILATIoN (PCV) valve.

There is less pressure in the crank when you add a breather at the valve cover. The consequence of this is you get more positive blow-by from the combustion chamber past the piston rings and into the crankcase. More blow-by means less cylinder pressure...less cylinder pressure means the burn is slower and less complete...the result is more emissions and less power.

If you want to do this right and remove oil vapor from the circulating crankcase before it goes into the intake valve then, get an oilcatch can and put a breather on the catch can. Then place the catch can in between the valve cover breather and the PCV valve.

Disconnecting the breather tube, which blows fresh intake air into the valve cover, and placing a breather on the valve cover just creates more blow-by and emissions. Eventually you have so much blow-by, you lose power.
