This is done intentionally, and repeats further throughout the installation. The main reason is it prevents long runs of grout lines. The installation will be stronger, and there’s no need for an expansion joint. Additionally, it’s harder to see if the grout joint shifts one direction or the other over a long run.

I don’t think it need to be done every fifth tile though- that’s a design choice by the installer.

Is there any way you can take a picture of the engine from directly above it?

It should be more towards the passenger side, maybe more forward then center. It may not say oil, but rather 5w-30 or something like that.

Hey there. I had the Chevy version of this truck once upon a time. The location depends on what engine you have:

If you have a 4-cylinder, cap should be near the center on top of the engine. If it’s the 4.3L V6 the cap will be off to one side, but still on top. I think we’re looking at the v6 here.

Look for a black or yellow cap, it should say OIL.

Instead of looking for a tv, look for a commercial display. They’re basically a computer monitor the size of a TV. Samsung makes a line that we use at work, and the cost is similar to a mid-range TV. They can function completely without internet.
