I thought the PS was the clean side and no need for a catch can there?

Two reasonons: 1. I read somewhere that you should. 2. When pulling that hose on the passenger side when I was dismantling the old engine and removing the intake manifold - there was a little oil in that tube.

So as a precaution, this is what I'm going to do. I will see if that was a wise decision or not. I can always remove it. We will see after my next oil change.

Finally installed the catch can this afternoon.

That frayed (protective sleeve) coolant line is next.

Hey all. I was going through my paper work, notes and receipts to file away. I came across a note stating that a crankshaft relearn may be required. The operative word being "may". It came directly from my build books. I assumed that since my Tahoe started right up with the new engine that it fell in the negative side of the word "may". In other words not required. Second guessing myself now. Thoughts? Is a crankshaft relearn required?

I didn't have to do a relearn on my LQ4 that I rebuilt last Spring. I also asked my buddy that's pretty savvy with these engines and he also told me he's never have to do it himself. So IDK. Do you have HP Tuners? You can do it with that.

How are going to address that fraying hose protector thingy BTW? I have the same on my trucks and find it unsightly.

It's not necessarily required, but recommended. It may ward off a future P0300, or intermittent long crank times. Quick and easy to do with a good scanner.

The description of the relationship between the crank and cam sensors is explained in the first several minutes of this video:

Thank you for the response. Yes, I have a tuner that can accomplish the relearn. It's running great so not sure if I want to go through the steps - although pretty straight forward based on the video Flees provided. Probably going to replace the hose with some braided hose I have - I'll provide pictures when I get around to changing it.

Thank you for the response. After listening to this video, I found a video on crankshaft relearn very simple to do.

This is the hose (AN-10) I will using to replace the hose with the frayed protective sleeve.
