PCV Catch Can Install

[northern piper]

typically I can drain about a shotglass of "gunk" out per oil change (~4000km) in the winter. In the summer it'd be more like teaspoonful. While it's not really that much liquid, I think it's better not in the intake or leaking all over the block. My filter, which admittedly is a compressor filter not a true catch can is only about 1 inch in diameter by about 3 inches long. So, not a full coke can by any means.

hey gang. just a follow up since i received the OCC and installed it yesterday. here's some photos.

hope to go for a drive today and check it out.

question again: i noticed the breather line had deposited a mess from it's port [in the hose] right in front of the throttle body. anyone else have this? or did it occur because i've been running the pcv valve disconnected?

*sorry about that, i think i've made the photobucket account changes so you can see them now.*

It is likely that the deposit is from the PCV line being disconnected.
I would advise against disconnecting the PCV line.....it will cause sludge buidlup inside the motor, and also cause the oil to break down much faster.
Better to have a mess in the intake from the PCV than the problems caused by not having it.

Once you install a catch can system, make sure to verify that you still have a good and powerful draw through the PCV valve.
You do not want the installation to reduce the flow in any way.

How can one see these photos. I just registered at the site. But still don't know how to find the photos.

A good premium PCV valve mounted above the valve cover works good, the oil will go back into the valve cover.

The link to the photos, I think that you were logged in when you copied the link.....
You will need to log out......and go into the pictures as a guest.....then copy and past the link.
You will also need to have access to your pictures available for guests.
How do I know this?.......I have made the same mistake with trying to link to my pictures.

As I have mentioned.....beating a dead horse......the oil from the PCV can be a pain.....but it is SUPER important that the PCV flow not be reduced or stopped.......it is super critical to the life of your motor.

If using a Catch can, PCV valve, fuel filters, oil seperators, it's best to go with an external filter, so the PCV emissions don't contaminate you MAF, IACT, and throttle body.

But don't forget to plug the hole where the breather went....or you will get lean codes, etc.

I was hoping to connect a wet injection Nitrous oxide (N20) system to that port for some more horse power.

sorry about that! hopefully i've modified the photobucket settings.

daniel: a good premium pcv valve? are you talking about a air/ oil separator?

wiswind: i've been critical with my amsoil's longevity of lately, however it's probably all due to my "modification." i look forward to further analysis and see how it's doing.
and in checking flow- when i touch the line near the pcv valve i feel a studder-like pulse. that was there before the OCC install, and i felt it again now.

question now on the proper flow of the air with the pcv valve connected. will the breather line only be a inlet, or will it still be used for a outlet?

i finally drove it today. 10 miles. and i swore i started to feel a surging when decelerating. now i'll look at those posts and see if i've got something else to concern myself with.

[wiswind]

The breather should be ONLY a input.......air flowing into the crankcase to replace the air drawn out through the PCV valve.

To check flow, I usually lift the PCV valve out of the valve cover with the motor running and hear it "hiss" maybe put a finger over the end to feel the vaccum.......can check for soft hoses that may collapse that way.

I have been running Redline oil......and keep my oil change interval at 5000 miles.......even a bit shorter in the winter.
So that would indicate that I am not into extended oil change interval.
For some.....extending the OCI works....but I would verify it by having the oil tested......you take a sample and send it in to a lab.
