Looks like it! I'm shocked that front valance made it through this adventure, it looks like it was close!

I'll be doing an Edelbrock or Whipple unit at some point this summer. Stock headers most likely. I don't really have any interest in the centrifugal units, just not my cup of tea.

I understand the mechanics behind it all. I'm just saying I've never found a single case of a motor blowing up due to carbon in my years of research. To me that means it doesn't happen. If all this carbon was really causing blown motors they would have revised the design for all of the millions of cars a year sold with this technology. Exactly. The only real fix (at this time) is adding an auxiliary injector. Many manufacturers have started doing this already. I don't think I've ever seen one report of "sticking". They might not have a full ROM but again that's not going to "blow your engine". IMO a catch can is a "half assed", as you say, preventative measure. It's doing something (maybe), but its definitely not a solution to the design flaw and I've spent hours and hours of research on this issue 'my friend'. I'm not trying to start arguments here, I'm simply saying that carbon build up isn't the end of the world and your truck is going to be fine, catch can or not.

Problems such as? Please elaborate. Reduce build up. Reduce being the key word. This isn't a SOLUTION its a band-aid. There are many DI platforms how ever where these catch cans do catch oil but do not affect the amount of build up on the valves at all. Its been proven over and over again for many years. You cant argue the data, lol.

Has it been proven that this is actually happening? People have claimed this for years and I have still never seen any proof. The other one I hear is "a chunk of carbon could fall off the valve and score your cylinder walls". Again... Never ever seen it. The worst I have seen with the euro cars that have been running this tech for years and years is the valves gum up to the point that they don't fully open and close. At that point you obviously get a service engine code usually paired with rough idle. I've seen more then a few cars show these symptoms and then be manually cleaned with great results and zero issues post cleaning.

I'm not denying carbon build up. I'm saying carbon build up isnt that big a deal. It robs power for sure but like I said its part of the package with all these direct injection motors. They have had this issue for 7-8 years. Trust me, I know. Ive had my Audi "carbon cleaned" 3 times in 4 years and it costs about 800$ each time. I consider it cost of ownership. The only way to do it is open the motor up and scrub the valves manually or with a walnut blaster. Catch can does nothing, cleaners do nothing, its been proven over and over and over. Its just now that the domestic companies are starting to use this technology more frequently these debates are starting to come back up again. My Audi at its first carbon cleaning, just for reference:

How did you mount that light bar? That location looks pretty slick.

Lots of interesting info in here. IMO adding a catch can obviously wont hurt anything but long term I really don't think its all that much benefit. If you search around the internet all these new direct injection motors (foreign and domestic) have this carbon build up and oil blow by, its just the nature of the beast. I think the hype is a bit over blown.

Ask and you shall receive. These test results were on a 2008 5.3 but you get the idea. Results should be very similar with the new body 5.3 as well. Air flow is air flow after all. http://www.gmfullsize.com/forum/showthread.php?p=5045477#post5045477

Those look fantastic

This is absolutely awesome. I'd love more details and photos of this in action!

I'm going to quote this and bump it to the later pages as I just spent a good 10 minutes digging back through this to find it, haha. Maybe we can get this put on page one for the time being? While its not a permanent fix IMO it will help owners who are trying to resolve this annoyance.

not all the time but any tight corner situation that was close to full lock or full lock

Stock All-Terrains. It was in the back inside corner of the wheel well liner. It was an easy trim. About 4"x4" did it.
