Received mine yesterday and it works great. Fits without any issue and is straight up and down on my truck. Should make the next oil change go a lot smoother.

How difficult was it to get the old one off the valve cover, and did you end up breaking any of the plastic off that you struggled to find among the rockers?

Not sure what you mean, there wasn't any old tube on my 2018. Just the oil cap, which all I did was take that off, install the fill tube, and then put the oil cap on the top of the fill tube. It ended up looking just like the pictures posted earlier in this thread.

Did the cap off your truck fit, or did you need to get the newer cap as well?

Same on my 2018. No fitment issues at all with the 2019+ tube on the rocker cover or the oil cap on the tube.

Ordered one, thanks @LDM

Hi all, first post here but been lurking for a while! Just put on the 19+ fill tube myself and have to say it's a little sloppy fit. It will wiggle around some and I can see the blue o-ring easily and somewhat concerned it is not going to keep trash from entering the valve cover. What's some of yours looking like? Going to try to take a look at a 2020 we have a work to see if it compares.

This was my thoughts as well

I'll post up when I do it... being in the middle of nowhere typically means even my simple projects take some time to get off the ground. I'll shoot for an April update.

Were you able to make the 2019 oil filler tube work for your 2016 5.3? I've searched all over and can't verify it. I just changed oil yesterday and went through 4 different funnels, two flex, two regular, a measuring cup, and tried to hit the hole with a 5qt Mobil 1 bottle. The flex went in the hole but was so slow it took 20 minutes to get 8 quarts in. Ridiculous! A job that used to take 10 minutes now takes 30 minutes by the time you dribble oil in at a snail's pace then clean everything up trying multiple devices, drips, runs, etc. WTF were they thinking? I don't want to have to carve something out with a Dremel, but may have to. Anybody else have any luck with the one mentioned?

Having just posted that, just saw the newest posts about it working. Great news!

Mine does move around a bit in the grommet but I think that is just because the grommet is rubber instead of a harder plastic material. I can't see the o-ring on mine unless I move it around. I don't think any debris is going to be able to enter past the o-ring on mine. But I also haven't been able to try using it at all because I haven't had to add any oil since my last oil change. I'll see how it works out next oil change but just the fact that I'll be able to use a larger funnel makes it well worth it to me.

Mine moves excessively, so much I have a rag wrapped around the joint and will be pulling the valve cover off soon to remove the extended fill tube. I have a feeling that it'll screw directly into the aluminum valve cover tightly, but at this point I'm thinking I will just leave it as it was. I noticed the coil cover was a little tricky to get off now but it does clear the tube. I noticed the coil cover on the 2019+ are a little different to allow easier removal. I actually ordered a used valve cover off ebay from a totaled 2017 just to see how things look. Waiting to pull my valve cover until a few more under hood parts show up so I can do all the work at once. I'll try to get some pictures if anyone's interested, but I'd recommend against this addition, and double check what you have if you already done it. Kinda stinks having to remove the valve cover just to get this tube off, which I admittedly knew before hand!

I thought I'd add to this thread, since I've been following it recently, and decided to purchase the "Newer 2019+" fill tube. I saw where the current cap opening would be an issue for adding oil. I ordered the Fill Tube here . It took about 3-4 weeks to get, so it may have been affected by the covid19 shut downs. Anyway, it came in & I installed it today. As mentioned before, it's not "stiff" tight in the existing opening and can be wiggled around. However, once in (it clicks to a snap lock" you can't get it back off or at least I didn't force it, as I didn't want to break it. The existing Cap fits fine, so I think all is well. Here's my pictures.

Since I wasn't happy with the fitment on mine, I went all the way with things. Pulled the valve cover, removed the short tube from the factory and installed the 2019+ tube and coil cover. All is well again! BBK shorty headers fell on too!

Larry, could you post the P/N's you had to buy?

Chev85 · August 12, 2020

Certainly;

Filler Tube - 12691785

Upper Insulator - 12674122

Valve Cover Gasket - 12619787

I did not need the valve cover gasket. They're reusable but for $4.00 it was good insurance to have it. I cleaned the head surface and gasket, which stayed in the valve cover, with a shop towel and rubbing alcohol. Set it back on carefully and did a two step torque sequence from center bolts out. 44 in lbs first pass, 89 in lbs second pass.

Maybe I don't understand what you did. Why did you pull the valve cover? Did you have to remove or install something in the valve cover to install the new Filler tube? Does this make it sturdier? I just removed the old filler cap & twisted/ screwed the the filler tube in the existing VC. It does wiggle some & I can see the top of the blue O-ring seal. couldn't you just replace the new plastic cover without removing the VC?

Originally, I came across this post about the newer filler tube fitting right on our trucks. I ordered one since it was cheap and liked how it made adding oil easier but also wanted it for later adding a catch can and not fighting the hoses to get to the oil cap. When I put mine on, it was a very loose fit and had me questioning if water and/or dirt could seep past the o-ring entering the engine. I noticed that there is already a short plastic fill tube on our trucks. The oil cap does not screw directly into the aluminum valve cover. You can see the new tube screwed into the short original tube in my one picture above. With the locking tabs on the fill tube(s) you can either twist them off till you break the tab and try to fish out the broken piece that falls into the rocker area, or remove the valve cover and use a small pick to release the tab. After I got mine all apart, it is was a much tighter fit while screwing the long tube directly into the aluminum valve cover. Doesn't move at all and seals nicely. Since I struggled a little getting the original plastic coil cover off over the long tube, I ordered the 2019+ plastic cover as well. Fits like a glove, and with the gusset on the long tube at the elbow, I'm pretty certain the original coil cover would not even fit with the new tube screwed directly into the valve cover.

Does that make any sense? I'm trying to describe it well but feel like I'm rambling! Compare my last picture to the others above. You can see how the fill tube is sitting lower and how it fits with the new plastic cover that is notched out instead of just a hole.
