Those Felpro gaskets look bad to only be one year old. Ouch.

Default felpro

Used felpro on mine as the metal GM was not available at the time and my original gm'* looked worse than that. So far so good. She never uses coolant.
Corvettcrazy, did you use felpro'*? Didn't pick that up in your post.

On the coolant elbow, you're using the RTV as an assembly lube. You can't let it skin over. It needs to stay soft so you can assemble everything. That coolant elbow has to slide into the LIM and accessory bracket at the same time, and they are positioned perpendicular to each other.
I was refering to the LIM corners, but that'* alright.

Why not use silicone grease to lube the elbow o-rings instead?

I've used it, and it works fine for getting the parts in. Of course, it does next to nothing for sealing.

Why don't the o-rings seal by themselves then? Isn't that what they're for?

Yep, they're supposed to, and many time do just that. If you're one of the people who have a leak develop at the O-ring, you're likely going to want to give it a little "help" the next time you do one.

If you use RTV, it will add life to the o-rings on the elbow. Many coolant leaks develop here. RTV will lube the install, and seal against possible leaks. This is a 'best practice' developed here on this Forum for good reason.

Alright, how much do you put on? Do you back it up all the way to the flange?

A 1/8" bead all the way around the o-ring, on the side that will enter the LIM or bracket FIRST. So the insertion forces it into the O-ring grooves of the elbow.
