Engine valve cover replacement/swap

Hello,

The valve cover from a 2009 Denali 6.2L will not fit the 2007 Denali 6.2L.
They are different with different part numbers.
The OEM part numbers for the 2007 Denali 6.2L are 12582224 on the right and 12570427 on the left.

I have attached replacement procedure below for your reference.

Let me know of any questions.
Thank you.

Hi Sean,

Thanks for your prompt reply. Actually, I bought valve cover of 2009 from one of the guys I know from the spare parts shop. He said there is only difference in PCV valve length that can be altered. I have searched each and every shop in my city and they all are selling for 2009 with updated baffle plate.

I will try to install it and let you know.

Sounds good. Let me know.

Hi Sean,

Today I changed the valve cover from Yukon Denali 2009 into my 2007. Car started fine no leakage till now. Before my car was running on an old valve cover with variable orifice PCV and now I changed to 2009 upgraded valve cover with fixed orifice PCV valve. No fault codes till now. Running perfect.

That is great news. Glad it is working.
Appreciate you sharing this information. I am sure it will help the next person.

Thank you.

That is just great!
Thanks for the update.
