Maybe the Dorman one fits both tubes. The caps don’t need to screw in BTW. My Clean Side Separator just pushes on, the o-ring seals it up. But if I were you Id just but the OEM tube.

Which means I got to pull the valve cover again to replace it. :thumbsdown:

So after I put in the new battery, obviously the clock reset. Now I can't get the clock to put a time in. Anyone ever have this problem?
I can press any button on there and nothing happens.

Really? The NBS just screw on from the outside, no need to pull the valve cover.
Yeah it’s just a twist lock. Just like the cap. But when that locking tab locks in place in the cover there is no getting it out without breaking it and risking pieces falling into the head. Even with it off I used a pick and a screwdriver to try and unlock the tab and no go. Had to break it apart some to get it out.

This Dorman part is definitely garbage.

Woooow I will have to try that next time I go out into the garage. I was just out there to put the z71 skid plate on, and quickly found out why people on here say you need those GM self tapping screws. Damnit.
the old nbs ones are the same bolt, if you wander around the junkyard you can probably find a few for cheap, Stealer is going to want $7~9 each

Are the ones that got the skid plate from the factory held in place by the GM self tapping screws? Or were the bolt holes threaded? The part number for the fasteners I’ve seen on here were self tappers but I don’t know if that’s for the normal one or what. If the bolts aren’t self tapping, I’ll have to get a tap :/

All I know is that my bolt holes aren’t threaded. Will swing by a parts yard soon though. Do you know what size the heads were? I just wanna have the pates on before snow is on the ground
I believe they are 15mm but I could be wrong, those are tapered though easy to spot, you will probably a see at least a couple under every gm truck/suv in the yard laying on the ground
