Guess if a blingy chrome key fob is your thing, that's $40 more than the dorman to hang out in your pocket
that's why it's called a upgrade, I changed my oem one like that on the 18 to a AJT designs, flat black
I have dropped it, stepped on it, flung it across the room, you name it.

Changed the oil yesterday. Ordered some more KnN filters thinking i was out. Anyone else noticed the change in design? The new filter is a bit shorter and it has more holes near the gasket. New and old filter were bought on amazon

I will let you know shortly, my amazon order was just delivered and when i get home ill look. I was also skeptical when i got some from Amazon last year or 2 yrs ago because they weren’t wrapped in clear plastic like they used to be… apparently k&n is saving the planet by not using plastic anymore…. I liked the wrap because you knew no debris or whatever could be in the filter unless it came from the factory and we all know how easily oil filter boxes open for some reason….

What 2nd battery system did you install? I have the Hellroaring Primary/Backup Battery system. Also, why do some hoods have the hood lift strut and springs and some do not? My suburban does not have the hood lift strut.
No idea on the hood strut. I can't recall what my 2010 D'max had under there. I wonder why some have a grounding wire, and some don't.

Anyway, I used this cheap-o Amazon version for the battery isolator. It looks just like the more popular Keyline one, but costs 1/2 as much. And it had like 12ft of red wire, and only 2ft of black. :shrug: I used the black and maybe 6-7ft of red.

Today I added the RC-knockoff 2" lower strut leveling block. Took most of the day, but that was with teaching my nephew all along the way (frustrating at times, but gotta guide the youngsters).

One the passenger side my CV boot has a small tear, and grease was all over. So now I'm shopping for boots/axles. $25 for a boot kit vs. $70+ for a whole new axle.... I mean, the labor is the real cost, and I'll be doing that myself, and the whole CV is [probably...?] less messy, thus saving my labor/cleanup.... Hm....

Just a quick snap when we stopped to grab a burger after wrapping up. Man, you can barely even tell I had side moldings on there.... :rolleyes: <sigh> Eraser wheel/buffing kit is on the way, and you can actually see the tube with the new slim BSMs in the rear window. That's the coming weekend's project. Tomorrow I need to get the wipers/arms back on, before the storm arrives. Also really need to align my headlamps with the higher nose.

seems to be a pricing glitch what exactly is the make/model/engine size/year you are looking under?
that might be helpful


it's for my 11 hybrid. I went ahead and tossed one in my order of some brakes. we'll see what shows up haha. part number seems correct, just cheaper price under close out for some reason.

Took the tahoe out to my little patch of worthless desert and had a decent time.

Going from the jeep wrangler to the tahoe really shows how much more power and how much more comfortable it is.

On the way up there i noted something that keeps showing its ugly head.

Oil pressure fluctuating after several hours of highway driving.

I always assumed it was my stupid lifters sucking the oil pan dry and me getting some air in there.

Adding a little extra oil seemed to reduce it but then i notice a lower overall oil pressure after hours of driving, and less pressure rise.

Then while hauling the boat home, i discussed the issue with the father in law since it started happening.

Later youtube suddenly suggested a video explaining that over filling the pan in an ls can result in lower oil pressure due to foaming.


So i figured I'll bite, time to change the oil and switch to synthetic anyways.

So changed the oil,
And i didn't hit the top full line on the fill this time around.
Instead i targeted right in the middle of the full area.

Result was much better oil pressure and better oil pressure rise!!

Doing driving around the issue disappeared completely.

Until yesterday.
Right at the end of a two hour drive at anout 2k rpm the oil pressure started fluctuating.

Sitting a little over 40 on the gauge, it would dip down under it a bit, then go back over 40, sit there for a bit and then do it again.

Downshift to get the rpm back up and the pressure rise was good and solid, but back down and it returned?!?

I think its time for me to install a mechanical oil pressure gauge on one of the ports on the side of the block so i can see if it's doing it on both gauges...

I also got the bright idea to stop for a bit, let the oil settle with the engine off, but not long enough to allow the engine to cool off to see if that helped.

The answer was nope.

I also noticed it seems to happen when my voltage is up past the 14v mark...

So I'm not ruling out a possible alternator issue that shows up after several hours of driving...

I love the tahoe, but i also want it to catch fire sometimes... lol

On a happy note, it's fkn quick in those canyons.
I'm still loving the 6.0


I'm super behind but mine started fluctuating only on long hour plus road trips.. it was to fast to actually be a reading. oil is thick, I can't really flicker like a light bulb. it was the new "oem" sensor I had just put in from Amazon few 1000 miles earlier. replaced it with a dealer sensor and all fixed for a good 15k at this point. I'm convinced the Amazon oem is a counterfeit.

Yesterday after I found my hood strut where it is supposed to be I went through the engine bay and cleaned all the battery and engine grounds and reinstalled them. Also the cable from the positive post of the alternator to the positive post of the battery. I did not want to mess with that ground connection on the back of the engine so I cleaned the body post and checked the ohms from the engine to that cable and it was good. Did add a heavier cable from that post to the mount by the alternator, though, just in case. I feel like I should add another ground point to the body for that new cable but that will have to wait for another day. I also removed the bumper and cleaned those front chassis grounds but forgot to take a pic. I had gotten a low battery warning last week but I knew my battery was good, so I hope this fixes it, as well, those other miscellaneous electrical grounds under the hood that should forstall any problems.

Worth a shot.
I also need to get a factory cylinder head temp sensor; I'm suspecting some issues with it when the engine is cold.

Actually paid someone else to do an oil change on the 2012 because we're taking a camping trip starting this weekend and will be driving 1000 miles or so. It's a local quick lube that has competent techs who do good work. $95 out the door for 5w-40 Euro spec oil (engine mods).
