'17 Grand Sport parts issue - help
I'll try and make this short for everyone
I broke a clip on the Y pvc hose that going into the valve cover cause i was redoing the plastics
No big deal right - just order a new one or throw a piece of electric tape around cause it will hold with suction.
Since she's brand new - I ordered a new one - here is the issue
My Vin(which matches my reg, window sticker etc) was used to pull up the part from the Chevy dealer. 2 times the wrong part came even when bringing the part to the counter.
During the 3rd visit to Chevy I was told that I either mod the hose or engine because the part on the screen is the part i need and it's about 5" too short.
So i made them pop the hood on a Grand Sport on the lot - low and behold it had the same hose is mine- not the shorted one.
Long story short. Using the Vin from the GS on the lot we found the right part.
The dealer checked both Vin# to pull the build info, sticker, invoices etc.
It seems that on BOTH vin as far as service is concerned the GS is a reg Z51 2LT (which has the dry sump but in a slightly different spot. On the sales slide both Vin show them as a GS.
I have no idea how to handle this cause I did get the correct part ordered finally - but what if the car needs to be fixed - service will order the wrong stuff---- Any thoughts please ? Call GM ?
And as a side note - the hose for the Z51 can be ordered by itself, where as the hose for the GS - you have to order 4 parts to get it.

Is it possible your vin was pulling up the 2016 hose?

These are the dealer sheets
Mine is pulling part 24 on the right sheet
Which is saying its a 2017 dry sump z52 - that's the smaller hose in the original pic
The correct part is in the left pic in yellow - but you need to buy parts 2,3,4,5 to get part 2
I don't really understand how or why the car is coming up wrong on the service computers and correct on the sales computers

That is easy to figure out. Somebody in the bowels of GM or one of its subcontractors finger fumbled the data for your car. Hopefully, whoever designed the database designed it so there is only one master record that needs to be changed. If it is an old design there may be more than one master which can be a problem when chasing down the incorrect entries.

The 2017 Grand Sport PCV hoses are different than previous C7's (Non LT4)
The drivers side valve cover no longer is plumbed into the air intake. GM typically sells tubes like this with all the clips and other attachment pieces.

Is the 2017 Z51 the same?

Can you take some close ups of the intake valves? Even if only a hundred miles so we can see how early the coking starts.

Having owned both a 2015 Z51, and a 2017 Grand Sport I can tell you that the upper hose in your picture is from a 2017 LT1 dry sump engine. (Grand Sport, or Z51 makes no difference)
The lower hose in the picture is from a pre 2017 LT1 dry sump engine. The only difference is the location of the quick disconnects near the firewall, and a slight difference in the angle where it comes off of the valve cover. The oil tank is in the very same position for Z51, GS and Z06.
There may have been a carry over of the earlier design for early production models.

I wouldn't be too concerned, since you were able to get the correct piece. What happens in the future is out of everyone's control.
