Gonna have to do a little research on that.


In a perfect world i'd prefer something inline on the hose that could be quickly removed prior to any inspection.

Just saying...
Its generally bad to introduce oil and moisture into the intake system. However, the EPA and the green people think it's helping the environment. I don't have emissions in my area, so I'm not putting that stuff back into my motor. So far, I've seen no negative effects not having vacuum for ventilation...

Kenny camaro, do you clean the orifice out on the pcv? So you know the system is working properly, and not drawing oil in from the clean side then.

Maybe these Elite Engineering catch cans aren't that good? Maybe it's all just snake oil with these "catch cans" they tell us we need?

With that amount of build up in the short time since you cleaned it, I'd be interested in knowing what the Elite Engineering spokesperson, who likes to post in this forum, has to say about this.

It'll probably be crickets, but I had to ask.

I'm just glad Kenny is willing to share his results with us. The more I read about these catch cans the less I think I need one.

Seems to be a bigger issue on the LLT\LFX than the 8's. But I have seen guys post pics with several ounces of oil between oil changes in those cans!

I'm glad Kenny posted it too. Before this all people want to respond about if a catch can helps, is look at the oil in the can. Like I said before oil in the catch can doesn't prove it keeps the valves clean. It surprised me Kenny got that much oil and carbon buildup . Looks like my valves at 30k now, no catch can or manual cleaning. All I've done is pennzoil ultra platinum oil, kept the pcv valve clean, and everything is stock. I think next spring I'll try crc Gdi cleaner and take pictures again with the borescope.

The catch can is spliced into the line that goes directly into your intake manifold. The oil that ends up in the can was on a direct path into the intake system. No doubt about it. Does the can catch everything? No. But he would have had those 6-8oz's circulating through the manifold if he didn't have the can. When I first saw this thread, I was thinking that it was the Penzoil that was crap. And really, your pics don't do much to change my impression of that.

I’m thinking that the next oil change I do I am going to try Amsoil 5-50. I will be walnut blasting my intake valves in the spring /early summer every year. Even thinking about offering walnut blasting as a service for my local v-6 brethren.

In my opinion, the pics that Kenny posted seem to show excessive build up for only 8k miles. I don't see how an oil could be responsible for that unless it was a cheap non-synthetic. He had them blasted perfectly clean with his walnut shell method just a year ago. I don't know about you, but this has me concerned.

I don't know what the deal is with the Elite guy that posts here, but he doesn't seem to be too interested in responding back to clarify this issue. Heck, he can't even respond to my inquiries if the check valves are needed on a non-boosted application. The Elite engineering website says no, but he seems to recommend them even on a N/A setup with the E2X two suction source catch can. Makes it kind of confusing if you know what I mean.

Since Kenny doesn't have the clean-side separator on his car, is that why he suffered the kind of build up he witnessed in only 8k miles? I have the clean-side separator on mine, but no check valves. Maybe I should rent a borescope and check mine. However, with my super low miles, I don't think I would be a very good test candidate to determine if these catch cans really work as well as we're told they do.

Maybe Kenny needs the PCV drill mod? However, I believe most of the LFX's in '13 already had the larger orfice opening that the earlier models had an issue with. If it is truly the oil that makes all the difference, which I don't really see unless you never changed it or you used some cheap non-synthetic, what kind is the best?

I'm currently using Mobil 1 fully synthetic and changing mine every 3-5k miles or 12 months, which ever comes first. However, since I don't even have 5k miles on mine yet, I'm using the 12 month schedule.

The v-8 ‘s are still port injected, not direct injected. So they have gas washing over the intake valve cleaning them. That’s a different setup and a catch can is not as critical , allegedly.

No, I didn’t need the drill mod ,as I checked for that during my set up of the catch can. I am not running thecleanside separator. I didn’t have any oil in my intake tube and no noticeable oil on my 80 TB. I run wot nearly every day also. Not to 125 mph mind you, but I blast around quite often. In the first thread I did, there was a good posting about the Pennzoil. So I gave it a try. Maybe I’ll try something else.

After some research i've decided against going to the breathers and just keep cleaning my valves at every 5,000 mile oil change.
Since i drive this one like an old man anyhow i don't believe its ingesting a lot of oil and my understanding is it does that after letting off those high rpm romps.

Maybe Kenny just needs a lighter foot.
