Installing Environvent CCV on QSB 5.9

[David Hays]

This will likely go down as one of my typical stupid questions but…

I am going to replace my existing Walker Air Sep with Seaboard’s Envirovent CCV. I received it but didn’t find any instructions. No problem, I knew there were some great photos on the website so I checked that out.

I still have two questions. The first, is that the kit included one length of hose. I need two lengths of hose, one from the air filter and the other from the top of the engine housing. Am I just to cut the hose that came in the kit into two pieces?

Second question, uninstalling the Walker Air Sep. Pretty straightforward but how to I block off the hose that goes from the bottom of the Airsep filter to the crankcase?

Thanks.

Done

I spent a couple hours installing this today. I am a slow and poor mechanic. Anyone with decent skills would have taken 15 minutes.

I ran into a couple of surprises.

The first was that the threads for the plug needed that Tony pointed out to me were 3/8′ npt. Fortunately, I had one handy.

Secondly, I had some trouble with getting the new piece that connects the upper hose to the engine. The piece that was there from the Walker has an O-ring and a retaining ring held in place with a bolt. This was easy to remove. However, it was impossible to insert the new one in from the CCV. A quick check with my calipers showed that the opening in the engine is 1″ (25.4 mm). The diameter of the piece from the Walker Air Sep with the o-ring was 25.3 mm. The diameter of the new piece from SB was 25.6 mm in diameter. This meant that I couldn’t fit it in place. I finally just spent some quality time with a piece of course Emory paper followed by some 600 grit emery paper and got it to fit. I even remembered to use the Rectorseal,

Tony’s tip above about how to attach the hose first then cut it made the rest easy.

Don’t forget the Rectorseal 5 on that npt plug…

That was my plan Rob. So I just need to find a 1/4″ npt pipe plug and I should be good to go. I’ll see if I can get that done Friday as I’m not working.

Thanks again.

Don’t forget the Rectorseal 5 on that npt plug…

Thanks Tony. That is simple.

Photos

Here is my attempt at the photos. Let me know if they aren’t good enough. The first is the blue oil hose that drains the Walker filter coming out of the bottom.
The second is a shot of the starboard side of the engine where that blue oil line connects to the engine. At the bottom of the photo you can see where the oil pan connects to the engine.
The last one is a close up of where that blue hose connects to the engine.

Thanks Tony,

That sounds like a great way to do the hose.

I’ll see if I can get some good pics of the Walker drain and post them.

Have a great weekend. I know I will!

Upgrading to a QSB Envirorvent System from a Walker Airsep

David,

Nothing stupid…………….Run the hose in ONE piece ( cut only length as needed so it drapes right) to where it looks good , avoids chaffing and has only ONE low spot.. After you like what you see, then cut at the LOW spot and install the drip bottle .. Remember, on size never fits all.

If you cannot figure out how to block of the Walker drain, send me pics….. Not all are the same.

Tony
