Updated valve cover (for PCV) details

[iamdub]

I reckon it would be fine to get the one made for yours and leave it plug and play; no messing with changing hose sizes. Or modify your original since that's an easy task for you!



PN# 12571609 is the one that was installed by GM on my truck in December 2016.

Thanks for that number, James. I'll see if I can find a part number on my VLOM when I make it back out to the shop. I hope it's the new design cuz that's an expensive part!


I'm gonna see if the dealer has the updated valve covers for both engines so I can compare them in person.

I'm all for keeping it simple but was just trying to take TWO updated oil control measures in one shot if they were possible and at half the cost. As I often do, I'm probably just overthinking this. Mine doesn't really burn all that much oil, anyway. Maybe half a quart at 5,000 miles.

I did not get the new OEM part I purchased the dorman brand version of the new part through Rockauto...
I bought the Dorman 264-969 for around $45... it has a lifetime warranty vs 12 months for the 12642655 oem...
I replaced the PCV and its hose as part of the rebuild since the original hose was oil soaked.

the VLOM
I got the Dorman product, Dorman 917-162 also from Rockauto. I paid about $131 for it. again lifetime warranty vs OE@ 12 months.

Here are some current photos of my stock valve covers.

For some reason the passenger side is really clean looking but not so much on the driver side.

Consider this, for such a critical component, the warranty matters little if it is not known for being reliable as it affects so much else in this case. Not saying the part is inferior, I have no idea unlike the Dorman TECM for the transmission.

Soon I'm going to install GM# 12570427 valve cover, $115 from Amazon, because my catch can is catching 1 oz per 100 miles, NOT Good! Hopefully this updated VC will decrease oil consumption/accumulation dramatically.
