Just got a new 2018 Sierra with more bells and whistles than I've ever seen in a truck before. Sure learning a lot on these forums.
The catch can thing has my interest, I never even knew that was a problem, never had a direct injection vehicle before.
I'm looking under the hood on this thing and although it is difficult to see much it looks like there are two PCV valves, assuming that's what I think I'm seeing. They are right up front of the engine, one each side, with short tubes going into the intake air plenum. See attached photo of the front left side of the engine.
So question #1, are two PCVs what I am seeing?
Question #2, if so then I need either two catch cans, or one that does double duty, right?
I'm a little confident that the answers to my questions will be yes (still appreciate confirmation though) and if so this will be a plumbing nightmare. This truck has the eAssist which means the only open space for a can is the front left corner where the battery used to be, on eAssist it's up in the back right corner of the engine bay. And, there is no room at all left in that part of the engine bay, it is packed.
So I guess question #3 is, anyone come up with a creative way of solving this problem, besides hoses all across the top of the engine?
Thanks in advance for responses.
Good morning everyone,
I recently purchased a 2018 GMC Sierra Crew Cab SLT All-Terrain package. I'm personally wanting to install a leveling kit and I believe I've selected one. I've read a lot about leveling kits for 2017-18 trucks and this seems like a great kit. However, there isn't many reviews on this product by ReadyLift. The appeal of this lift is the UCA replacements and the <2" height it allows. I'm wanting to go with 305/55/20 or 285/60/20 tires with my stock AT wheels and I want as much clearance possible. I found maybe 2-3 members on here with this lift and I'll quote them below. My question is, will this work with my All-Terrain package? In the description of the kit it states, "Will not work on Z71 packaged vehicles with factory Rancho® struts." Yet on ReadyLift's website, there is nothing supporting that statement. Does anyone have any information or review for this kit? Thanks!
I’m sure this had been asked 20x but I can’t seem to find it. I’m looking to add some tow mirrors to my 2018 Sierra elevation package. Has power mirrors, non power fold, has defrost, and does not have turn signal. Which are best mirrors for this? Also can I hook into wiring harness and add turn signal as well? Thanks again!
Hey, so I am trying to replace the speaker wire in my rear door speakers and I cannot get the panel off that is on the column between the front door and rear door. This column panel has the speaker wires running up it into my rear door. How do I remove the panel without breaking the little red Clips inside? Thanks, Hunter

I'm trying to figure out what the max tire size is I can put on stock 20s in the 33" range. I'm looking at KO2s right now which I know BFGs run a little small. What is the max I can run if I level with a 2.0" level or if I run stock suspension? I have a 2018 Sierra Crew Cab NHT with stock 20" wheels.
I tried doing some searching and I think I can fit a 33 no problem but then I see other posts that just confuse me on the matter.
