Jeg's PCV oil separator

[Cowpie]

That would be about comparable to what I got in the same time frame on my 2013 Silverado.

Ok, how do you tie into the line? What I believe is the PCV has a solid molded plastic (?) line from the valve cover to the intake (about 12 inches long). Have you been just cutting that line and just splicing onto that?

 

I'm going to order the Jegs deal Monday.

Installed mine today. 2014 Silverado 6.2L 4X4 3,200 miles. I had maybe half a tea spoon of oil in the intake.

This was for my 2013 5.3L

 

1) remove engine cover.

 

2) Look to driver's side rear of valve cover. You will see PCV tube leading into an orifice there. There is a lever on the tube lip where it attaches. Slide the lever and remove line from orifice.

 

3) This line is a flexible plastic tube that leads to the top of the intake manifold. I cut the tube approximately 5-6" from where it leads into the intake manifold.

 

4) Attach 3/8" fuel line quality hose to the valve cover orifice and clamp with hose clamp. The hose you connect here will lead to the inlet of the catch can.

 

5) You will need to determine where you want your catch can mounted on the driver's side of the compartment to determine how much hose you need. make sure and use clamps on the hose at the catch can to avoid any possibilities of leakage.

 

6) run hose from the catch can to the tube you cut that is still in the intake manifold. The tubing will fit (very snuggly) inside the 3/8" hose. After you insert the tube into the hose at least a couple of inches, then use clamp to hold securely. Do not over tighten to avoid risk of collapsing the tube inside the hose.

 

That is all there is to it. Clean, simple install. The most difficult part is probably determining where you want the catch can and mounting it to that location. Keep in mind, you have to drain it occasionally, so make sure that you have it mounted where you can service it regularly.

 

I didn't take pics as I did the job, probably because I thought it was a very simple install that didn't require much mechanical aptitude, but I do have a series of pics of the finished job. Send me a PM with a contact email and I will email them to anyone.

Missed this the first time through...

 

But I'm also reading where you can remove the line and simply tie onto the nipple on the manifold and the PCV valve without cutting??

 

I ordered the Jegs Can today, probably be here later this week...probably install it this weekend when I get back into town. While similar installation, finding a mounting location might be fun, the 2500 with its hydroboost eliminates that location, I have a second battery in the driver's tray. I'm going to use the alternator bracket.

As previously noted, I bought a Jegs can. Installed it Saturday afternoon...here are my findings.

 

Boy this thing is small. Easy to find a home, but not a whole lot of capacity.

 

I drilled the stiffening crossmember on the driver's side (near the master cylinder), and mounted the can directly to the underside of that crossmember. Took about six feet of hose to hook up. I ended up breaking the hose fitting that connects to the valve cover...the release pulls out, its not a squeeze to release affair. I also found the other end is a 90* twist lock, so I ended up cutting the line at that end and reusing the twist lock...the other end left me a steel nipple that I simply put the hose on. I will order a replacement line, just to have it on hand. I used some spring-type hose clamps I had on hand to hold it together.

 

I drove less than 50 miles since the install and already have oil visible in the can...it seems to be working well, the line entering is hot, the line leaving is significantly cooler...between that and the loss of air velocity the can provides, the oil vapor has time to condense out and get trapped.

 

What I find interesting is that I use no oil between changes. I did not really expect to catch much...and now...

[sdeeter19555]

Well, here are my results...

 

Drove home 300 miles, and caught nearly an ounce of stuff...its not so much oil, it seems more like gas blowby and moisture? Its thin and watery. Caught nearly the same amount on the return trip.

 

The neat part was watching the catch can work, it swirls the air around the canister sort of like a centrifuge.

 

Now I'm considering a larger can...

I keep hearing people says it is small. Just how small? You took out an ounce in 300 miles. Will this be enough volume for a 3000 mile oil change? If not how often do you think you will need to empty the canister? Once a week, a month?

 

Thanks!

[sdeeter19555]

I would be lucky to get 1000 miles before it needed emptied...probably the trip up and back (600 miles) would have put it close to touching the filter media. Yes, its that small...

 

I was very surprised the amount of fluid captured...considering I didn't expect anything of significance.

As a follow-up, my findings are holding true...maybe 600 to 1000 miles between drainings.

for comparison, the Conceptual Polymer reservoir jar is 2" wide by 4" tall. The standard version uses the same filter at the Jegs unit. The top end version uses a much more refined filter that does a better job, using two different filter medias inside it. I use both, hooked inline. The standard for the first can, and the high efficiency filter for the second. Both with 2" x 4" reservoir jars. No need to pop the hood after a day of driving and dump it.

 

My CP setup....

Hopefully you can make out the pics I installed min Friday night

Got 1/4 cup after 4600 miles on the 4.3 I just traded

Seeing is believing! I wondered when I decided to put a catch can on if it was just a gimmick mod. I now am bumping up against 22,000 miles on my 2013, and the catch can setup has captured an average of 1 oz per 1000 miles. I have long since filled up a 16 oz drinking water bottle and just keep it around for discussion purposes. The winter, the stuff is usually milky looking like you guy's photos. In the summer, it stays primarily looking like oil. It is amazing the amount of condensation that builds up inside the engine and then gets sucked right back into the intake. But not on mine!

So, has anyone added a catch can on older trucks (2000-2006)? This looks like something you could add without any issues but will the older trucks need the extra capacity of the Mike Norris catch can or would the smaller Jegs catch can work just fine? Thinking about putting one on my 2002 Yukon XL 6.0L and I typically run 5000 miles between oil changes, no known issues with the PCV system or using excessive oil on mine. Just wondering about the advantages of adding a catch can to an IDI engine or how much oil one may expect from this vintage engine.
