[Erik Adam Rodriguez]

just the hg or the lim too

Those should be the same size as the coolant elbows. We typically recommend replacing the entire elbow, and the manufacturer often gives you new rings.

It came with 2 orange o-rings for the elbow bill, and 2 yellow ones that i put on the LIM. These 2 black ones are about the same size but one is thicker.

PCV Valve?

 

[BillBoost37]

You have two elbows.

PCV should only have one on a charged motor. If this was a fel pro set, read the box. It'll tell you what they are expecting.

I believe one is for the PCV valve, and the other is for the vacuum tree on top of the SC.
