Drained my RX catch can last night after changing the oil. I don't remember exactly when I drained it last. I'm guessing about 2,000 miles on this interval. A lot of water in this drain (I'm guessing due to cooler outside temps). During the winter I think I'll try to drain it at least once a month.

How many miles does this represent?

Information from Toyo that discusses the replacement of factory P rated tires with LT tires on light trucks: http://toyotires.com/sites/default/files/page-files/TSD-12-011%20Replacing%20Tires%20on%20Light%20Trucks.pdf

Is this an LT tire?

The hose that came with my RX catch can is 3/8"

The connection under the throttle body that goes into the valley of the motor is where the crankcase gases are collected. This connection appears to be in the same location on the 5.3 and 6.2. The factory vent hose is pretty short on the 6.2 and goes from under the TB to just above it to a fitting on the intake manifold. On the 5.3 the factory vent hose starts in the same location but goes back along the valve cover to a fitting on the intake manifold. When installing the RX catch can, a hose goes from this connection under the TB to the center port on the can. The second hose goes from the intake manifold to the catch can (off center connection on the RX catch can with the check valve). This is the suction side of the setup. The intake manifold creates vacuum that pulls off the gases from the crank case and through the catch can. The catch can is basically acting as an inline filter between the crankcase and intake manifold.

The can doesn't go to either one of those hoses. It connects to a fitting that vents the vapors from the valley area of the engine. Stock with no catch can, there is a hose that transfers these vapors directly into the intake manifold to be burned off during combustion. The catch can goes between this fitting and the intake manifold. The PCV rocker covers are vented into the intake tube (before the TB). This is the vent fitting on the 5.3 (located under the TB) and the hose runs along the driver side where it enters the intake manifold about half way back.

Emptied my RX catch can. This represents about 2200 miles.

Here is a product from CRC that I'm thinking about giving a try: http://crcindustries.com/auto/intake-valve-cleaner.php

Installed my RX catch can last week just before a trip. Collected about a tablespoon after 900 miles. Will empty again at next oil change. Installation was pretty easy and looks to be a quality piece.

I know the DOHC 3.4 V6 that was used in some 90's W-body GM cars did. Can't think of any others.

Thanks! I'm gonna be ordering the just the catch can from RX.

Newm: Thanks for the update. From what I saw in your install pics, you didn't buy the clean side separator contraption that goes on the oil fill hole on the valve cover? I'm leaning towards just ordering the catch can.

For those who have installed catch cans or plan to...please keep up posted on how much oil you catch (in x amount of miles too). Thanks!

I have my ScanGauge hooked up monitoring oil temperature. The highest I've seen so far is 230 then it came down to 220. This is while pulling my boat (maybe 2500 pounds) with A/C on, mostly flat terrain and 80 out. No load and its rarely over 208-210 which is what the engine will run at. I have noticed the higher the RPM's...the higher the oil temp. If I'm cruising in 6th and downshift into 5th, oil will go up about 10 degrees. Downshift into 4th and it goes up another 10 degrees.

Thanks for the info. Look forward to your update. If you would be willing to share price for everything you ordered that would be helpful too.

Which RX can did you order? I was on their website and don't see 2014 pickup engines as an application option. Thanks

I would try resetting the computer and see if that helps (disconnect battery for awhile).

This is the best I've seen so far. I had the cruise set at 55mph with a good 20mph tail wind. This is not typical for me. I've been averaging 16-17mpg throughout this cold winter. Now that it has warmed up I've been seeing 20mpg on interstate. Hopefully see 22mpg when we are off winter fuel and back to normal temps.

I'm looking to tune my 14 to primarliy reduce the torque manangment which is driving me nuts. At $307 through Amazon (http://www.amazon.com/DiabloSport-I1000-inTune-Vehicle-Programmer/dp/B0064IU5FW) this might be the most economical method.

What octane fuel are you running? Have you been monitoring KR?

What part of the country do you live in? I've noticed cold temps make a big differance.

I too have noticed a definate pattern between outside temp and V4 mode. When its -20F it won't go into V4 even at 55MPH. The warmer it gets the more V4 mode operation I see (along with better MPG).

I've noticed that temperature plays a big role in MPG's. We went through a -20F spurt and I would be lucky to get 14-15 MPG going 70MPH on flat road with no wind. Same road when 30F and no wind I'll get 18 MPG.

Ive had the Access Lorado on my Sierra for about 3 weeks now. Fit and finish is top notch.
