Just got my first truck, a 2006 Silveado 1500 with the 5.3, and I've got all the issues chased down now except for these last few...
The first is a P0455 error code, which is a leak somewhere in the evap system. My gas cap is new and down tight, so the next part I'm trying to look at is my vent valve/solenoid, which should be right next to the charcoal canister and tank. I think I've found it based on location, but what I'm seeing on my truck isn't matching either the videos or the parts I'm finding on rockauto. The only potentially cannister-like or vent-valve-like parts I've found next to the gas tank are what's in my picture here. These are right next to the front side of the tank, and have the same type of hoses running to them like I've seen in the videos, but aren't shaped nearly the same. Is this my canister and vent valve part I'm looking for?...
Canister and vent valve?
The second issue is the leak I'm seeing coming from my rear differential. It's at the front of the diff where the drive shaft ties in. How hard is it to change this seal? Any general advice here?...
Rear diff
And last is this rubber hose I found that terminates on top of the crank case. I was able to feel above the transmission and trace it as it runs toward the engine. It has some kind of Y branch in it just on top of the transmission, and continues forward further than I could feel. Just making sure this is some kind of vent hose that I don't need to worry about. The truck had some transmission work done just before I bought it, and I've already found some screw-ups when it was being put back together.
Vent hose?
I'm all ears. Thanks
